Definitions
- This invention relates to the field of endoprostheses for the treatment of blood-vessel bifurcation stenosis.
- This invention also relates to a purpose-built installation device.
- endoprostheses of this type may be said to have already given good service.
- a primary goal of this invention is to develop existing endoprostheses in order to facilitate and improve treatment of blood-vessel bifurcation stenosis.
- a first distal section aligned at least approximately with the proximal section and intended for insertion into one of the vessels branching off from the bifurcation, this distal section being attached to the proximal section by means of a laterally positioned connector;
- a second distal section placed at the side of the first distal section and intended for insertion into the second vessel branching off from the bifurcation, the two distal sections having their proximal ends joined by the second connector.
- the distal end of the proximal section is chamfered and the proximal end of the second distal section is tapered at the other side of the second connector and fits into the chamfer in the proximal section.
- chamfered shapes and tapered ends may have a variety of embodiments. They may, in particular, be delimited by flat or curved surfaces.
- Another important goal of this invention is to perfect the method of installing the above-mentioned endoprostheses.
- a second balloon of suitable nature for insertion into the second blood vessel branching off from the bifurcation.
- the first balloon incorporates a lateral recess to be positioned facing the bifurcation area with a view to housing the proximal end of the second balloon.
- the distal portion of the first balloon located downstream of the recess is of smaller diameter than the proximal portion of the balloon located upstream of the recess.

- FIG. 13 is a schematic cross-sectional view of a feeder tube for the double-balloon system.
- endoprosthesis 100 comprises three tubular sections ( 110 , 120 and 140 ) and two connectors ( 130 and 150 ).
- the first section ( 110 ) is a proximal section having as its centre axis 111 . It is intended for insertion into main stem T 1 of blood vessel V for treatment, upstream of the bifurcation.
- the first distal section ( 120 ) having as its section axis 121 is at least approximately aligned with proximal section 110 prior to use.
- This first distal section 120 is intended for insertion into blood vessel T 2 branching off from the bifurcation as is seen in particular in FIGS. 6 and 7.
- the first distal section ( 120 ) is attached to proximal section 10 by the first lateral connector ( 130 ).
- the second distal section ( 140 ), having as its axis 141 , is positioned at the side of the first distal section ( 120 ), and has the advantage of being parallel to the latter, prior to use.
- the second distal section ( 140 ) is intended to be inserted into blood vessel T 3 branching off from the bifurcation, as is seen in particular in FIGS. 6 and 7.
- the two distal sections 120 and 140 have their proximal ends ( 122 and 142 ) linked by the second connector ( 150 ).
- Each of section 110 , 120 and 140 is preferably formed from a tubular component perforated with a grid pattern of slits such that the structure of sections 110 , 120 and 140 allows them to expand along their circumferences.
- section 110 , 120 and 140 of endoprosthesis 100 can be manufactured from extruded cylindrical parts made of a bendable metal alloy such as 316L stainless steel.
- the external diameter of section of 110 , 120 and 140 typically ranges from 1 to 1.2 mm prior to use.
- the opening may take the form of a hexagon or diamond, as shown in the accompanying figures, taking on the appearance of grating following expansion against the inner surface of the coronary artery by means of a cylindrical balloon placed inside.
- the three sections 110 , 120 and 140 are preferably of equal diameter prior to expansion, i.e. prior to use.
- the respective axes ( 111 , 121 and 141 ) of sections 110 , 120 and 140 are coplanar and determine a plane of symmetry for the endoprosthesis. This plane of symmetry is parallel to the plane of FIG. 1.
- the first connector ( 130 ) has as its centre the above-mentioned plane of symmetry determined by axes 111 , 121 and 141 .
- Connector 130 links an area of distal end 113 of proximal section 110 with an area of proximal end 122 of the first distal section ( 120 ). Yet more specifically, articulation 130 preferably consists of a strip of constant width parallel to axes 111 and 121 . Articulation 130 is diametrically opposite the second distal section ( 140 ) with respect to axes 111 and 121 .
- Distal end 113 of proximal section 110 is provided with chamfer 115 in its peripheral area situated opposite connector 130 .
- Chamfer 115 can be determined by a plane that is inclined with respect to axis 111 , perpendicular to the above-mentioned plane of symmetry or, again, be curved, for instance, concave with respect to distal section 120 .
- Angular opening of the wall of proximal section 110 thus increases starting from connector 130 and turns through 360°, i.e. a complete tubular form around axis 111 .
- This cant ( 115 ) forms a type of arch located on the side opposite connector 130 embodying in the cylindrical structure forming proximal section 110 the shape of the ostium of the blood vessel branching off from the coronary bifurcation onto which it will be applied.
- proximal end 142 of the second distal section ( 140 ) is tapered at the other side of the second connector ( 150 ). It stretches forwards in its peripheral area opposite the second connector ( 150 ).
- This tapered portion ( 144 ) may also be determined by a plane that is inclined with reference to axis 121 , perpendicular to the plane of symmetry or, again, by a curved surface.
- distal portion 113 with the corner cut off ( 115 ) of proximal section 110 is fixed together harmoniously with the proximal ( 144 ) of section 140 of the endoprosthesis and ensures maximum coverage of the dilated coronary bifurcation area.
- the whole of the grid of the bifurcated endoprosthesis ( 100 ) covers the proximal and distal portions of the two coronary branching arteries and the whole of the dilated bifurcation area.
- the first connector ( 130 ) preferably forms an integral part i.e. it is not joined onto sections 110 and 120 .
- first connector ( 130 ) and sections 110 and 120 are preferably manufactured from a single part in which connector 130 is formed via machining.
- the second connector ( 150 ) is also centred with reference to the plane of symmetry determined by axes 111 , 121 and 141 .
- the second connector ( 150 ) extends in a direction that is transversal to the above-mentioned axes 111 , 121 and 141 and links adjacent areas of proximal ends 122 and 142 of distal sections 120 and 140 .
- the second connector ( 150 ) is preferably joined to proximal ends 122 and 142 of sections 120 and 140 by means of, for example, laser welding.
- This aspect of the invention can, naturally, be embodied by a range of variants in that the second connector ( 150 ) could form an integral part with distal sections 120 and 140 formed from a single part, while connector 130 would be joined by means of, for example, laser welding to the distal end of proximal section 110 and the proximal end of distal section 120 .
- bifurcated endoprosthesis 100 for the coronary artery conforming with this invention has the following dimensions:
- the total length of endoprosthesis 100 measured from proximal end 112 of proxinmal section 110 to distal end 123 of distal section 120 is of the order of 15 mm;
- the diameter of sections 110 , 120 and 140 is of the order of 1 mm prior to expansion
- proximal section 110 is of the order of 7.5 mm prior to expansion
- the length of distal section 120 is of the order of 7 mm prior to expansion
- the length of distal section 140 is of the order of 9 mm prior to expansion
- the length of connector 130 is of the order of 0.5 to 1 mm.
- the diameter of distal sections 120 and 140 in their expanded state is of the order of 3 mm while the diameter of proximal section 110 is of the order of 3.5 mm.
- this instrument ( 200 ) comprises two balloons ( 210 and 230 ).
- the first balloon ( 210 ) is of a length consonant with its purpose of being positioned inside two approximately aligned sections (T 1 and T 2 ) of vessel V for treatment: main stem T 1 and a branching vessel T 2 , situated one on either side of the bifurcation area respectively, or, again, of being positioned inside proximal section 110 and distal section 120 of endoprosthesis 100 .
- the second balloon ( 230 ) is consonant with its purpose of being positioned in the second blood vessel (T 3 ) branching off from the bifurcation.
- Balloon 230 is preferably shorter than balloon 210 .
- the two balloons 210 and 230 are preferably formed from generally cylindrical elongated tubular items centred upon axes 212 and 232 and having their ends ( 214 and 216 ; 234 and 236 ) more or less rounded.
- the main balloon ( 210 ) preferably incorporates a recess in its side ( 218 ) suitable for housing proximal end 236 of the second balloon ( 230 ) as shown in FIG. 10.
- proximal portion 219 of balloon 210 located upstream of recess 218 is preferably of greater diameter than distal portion 217 of the same balloon located downstream of recess 218 .
- Each of the balloons 210 and 230 is preferably fitted with a radio-opaque tracer ( 220 and 240 ).
- Tracers 220 and 240 are preferably located at the centres of their respective balloons 210 and 230 .
- Tracers 220 and 240 may, for example, be carried by hollow internal tubes 221 and 241 housing metallic guides 222 and 242 having as their centres axes 212 and 232 and passing axially through balloons 210 and 230 respectively.
- Tracers 220 and 240 are preferably located halfway along balloons 210 and 230 .
- Balloons 210 and 230 are prolonged a; their proximal ends 216 and 236 by, respectively, tubes 224 and 244 , of narrow cross-section, designed to feed and, consequently, dilate balloons 210 and 230 .
- Tubes 224 and 244 preferably house guides 222 and 242 . More specifically, each of the two tubes 224 and 244 preferably has two lumina: the first lumen houses a guide ( 222 and 242 ) and opens into the associated internal tube ( 221 and 241 ) and the second lumen, used for inflating the balloons, opens into the inside surface of the balloons ( 210 and 230 ).
- internal tube 221 inside the first balloon ( 210 ) is preferably off-centre with respect to axis 212 in order to allow for the presence of recess 218 as is seen in FIG. 8.
- Inflation tubes 224 and 244 are joined at a certain distance from balloons 210 and 230 and are preferably attached by their proximal ends to a stiffer but both flexible and hollow common component 250 with two internal lumina ( 253 and 254 ) linked with inflation tubes 224 and 244 respectively or, more specifically, the said above-mentioned second inflation lumina of these tubes.
- Component 250 is, moreover, itself fitted at its proximal end ( 252 ) with two connection systems with fluid sources linked with lumina 253 and 254 respectively, allowing balloons 210 and 230 to be expanded.
- These connection systems may, for example, be of the type known as “Luer-Lock”.
- a variant on this is that the above-mentioned connection systems may be adapted to take a standard inflation syringe tip.
- connection systems communicating with, respectively, lumina 253 and 254 formed inside component 250 should allow the two balloons ( 210 and 230 ) to be expanded separately.
- Balloons 210 and 230 are preferably covered prior to use with a removable sheath ( 260 ).
- Sheath 260 covers the fill length of endoprosthesis 100 , i.e. preferably a minimum of 15 to 20 mm.
- Sheath 260 is preferably linked at its proximal end to a wire ( 262 ) facilitating removal of sheath 260 by pulling the said wire 262 .
- Wire 262 preferably passes through common tube 250 .
- Sheath 260 can, however, be omitted when the balloon system alone is used, i.e. without endoprosthesis 100 .
- connection systems shown in FIG. 12 are referred to as 252 .
- reference n° 270 in FIG. 12 labels a schematic inflation system comprising a pressure gauge ( 272 ) adapted for linkage to one of the connection system ( 252 ) with a view to dilating one of balloons 210 and 230 .
- Reference n° 253 and n° 254 in FIG. 13 label the two feeder lumina linking connection systems 252 with tubes 224 and 244 respectively.
- reference n° 255 in FIG. 13 labels the lumen housing the wire ( 262 ) facilitating the removal of sheath 260 .
- asymmetric double balloon 200 for coronary angioplasty conforming with this invention has the following dimensions:
- guide-wires 222 and 242 are 0.036 cm (0.014 inch) guide-wires
- the longer balloon ( 210 ) is 20 to 25 mm in length, depending on the model;
- its proximal portion ( 219 ) is approximately 3.5 mm in diameter and approximately 6.5 mm in length after inflation;
- recess 218 is approximately 3.5 mm in length
- distal portion 217 is approximately 10 mm in length and approximately 3 mm in diameter after inflation;
- the second balloon ( 230 ) is approximately 13 mm in length and approximately 3 mm in diameter after inflation;
- tubes 224 and 244 are joined approximately 10 mm from the proximal end ( 216 ) of balloon 210 ;
- the lengths of the two tubes 224 and 244 between the point at which they join and common component 250 may range from approximately 20 to 30 cm;

Abstract
An endoprosthesis for the treatment of blood-vessel bifurcation stenosis. The endoprosthesis comprises three tubular sections and two connectors. A first distal section is aligned at least approximately with a proximal section. The first distal section is intended for insertion into a first blood vessel branching off on the bifurcation. The first distal section is linked to the proximal section by a first lateral connector. A second distal section, located at the side of the first distal section is intended for insertion into a second vessel branching off from the bifurcation. The two distal sections have their proximal ends linked by a second connector.
Description
- This invention relates to the field of endoprostheses for the treatment of blood-vessel bifurcation stenosis.
- This invention also relates to a purpose-built installation device.
- It has already been suggested that stenosis found in coronary arteries be treated using endoprostheses formed from tubular structures perforated with a grid pattern of slits and consequently expandable following placement at the site of stenosis. In most cases these endoprostheses are expanded by inflating a balloon which is placed inside them and subsequently withdrawn.
- Generally speaking, endoprostheses of this type may be said to have already given good service.
- They are not, however, fully satisfactory.
- The applicant has, in particular, observed that standard endoprostheses are not fully satisfactory when, as is frequently the case, there is stenosis at a blood-vessel bifurcation. In such cases, treatment using standard endoprostheses requires two separate endoprostheses. One of these is placed in each of the two vessels branching off from the bifurcation and their positioning in relation to each other is adjusted as finely as possible to ensure optimal cover of the bifurcation area.
- A primary goal of this invention is to develop existing endoprostheses in order to facilitate and improve treatment of blood-vessel bifurcation stenosis.
- This goal is attained by this invention through the use of an endoprosthesis comprising three tubular sections and two connectors, namely:
- a proximal section;
- a first distal section aligned at least approximately with the proximal section and intended for insertion into one of the vessels branching off from the bifurcation, this distal section being attached to the proximal section by means of a laterally positioned connector; and
- a second distal section placed at the side of the first distal section and intended for insertion into the second vessel branching off from the bifurcation, the two distal sections having their proximal ends joined by the second connector.
- In accordance with another advantageous feature of this invention, the distal end of the proximal section is chamfered and the proximal end of the second distal section is tapered at the other side of the second connector and fits into the chamfer in the proximal section.
- The above-mentioned chamfered shapes and tapered ends may have a variety of embodiments. They may, in particular, be delimited by flat or curved surfaces.
- Another important goal of this invention is to perfect the method of installing the above-mentioned endoprostheses.
- According to this invention this goal is attained by using a double-balloon system, as follows:
- a first balloon of suitable length for insertion into two approximately aligned sections of the blood vessel to be treated: the main stem and the first branching blood vessel, on either side of the bifurcation area respectively; and
- a second balloon of suitable nature for insertion into the second blood vessel branching off from the bifurcation.
- In accordance with another advantageous feature of the invention, the first balloon incorporates a lateral recess to be positioned facing the bifurcation area with a view to housing the proximal end of the second balloon.
- In accordance with another advantageous feature of this invention, the distal portion of the first balloon located downstream of the recess is of smaller diameter than the proximal portion of the balloon located upstream of the recess.
- Further features, goals and advantages of the invention will be apparent on reading the following detailed description as illustrated in the corresponding accompanying drawings, which are given as non-exhaustive examples and in which:

- The first item described will be the structure of
endoprosthesis 100 in accordance with the invention and illustrated in FIGS. 1 to 7. As was mentioned earlier,endoprosthesis 100 comprises three tubular sections (110, 120 and 140) and two connectors (130 and 150). - The first section (110) is a proximal section having as its
centre axis 111. It is intended for insertion into main stem T1 of blood vessel V for treatment, upstream of the bifurcation. - The first distal section (120) having as its
section axis 121 is at least approximately aligned withproximal section 110 prior to use. This firstdistal section 120 is intended for insertion into blood vessel T2 branching off from the bifurcation as is seen in particular in FIGS. 6 and 7. - The first distal section (120) is attached to proximal section 10 by the first lateral connector (130).
- The second distal section (140), having as its
axis 141, is positioned at the side of the first distal section (120), and has the advantage of being parallel to the latter, prior to use. The second distal section (140) is intended to be inserted into blood vessel T3 branching off from the bifurcation, as is seen in particular in FIGS. 6 and 7. - The two
distal sections - Each of
section sections - In practice,
section endoprosthesis 100 can be manufactured from extruded cylindrical parts made of a bendable metal alloy such as 316L stainless steel. The external diameter of section of 110, 120 and 140 typically ranges from 1 to 1.2 mm prior to use. - There can be a range of variants of the grid pattern cut into
sections - As the basic structure of expandable
tubular components - The three
sections - The respective axes (111, 121 and 141) of
sections - The first connector (130) has as its centre the above-mentioned plane of symmetry determined by
axes -
Connector 130 links an area ofdistal end 113 ofproximal section 110 with an area ofproximal end 122 of the first distal section (120). Yet more specifically,articulation 130 preferably consists of a strip of constant width parallel toaxes Articulation 130 is diametrically opposite the second distal section (140) with respect toaxes -
Distal end 113 ofproximal section 110 is provided withchamfer 115 in its peripheral area situated oppositeconnector 130.Chamfer 115 can be determined by a plane that is inclined with respect toaxis 111, perpendicular to the above-mentioned plane of symmetry or, again, be curved, for instance, concave with respect todistal section 120. Angular opening of the wall ofproximal section 110 thus increases starting fromconnector 130 and turns through 360°, i.e. a complete tubular form aroundaxis 111. - This cant (115) forms a type of arch located on the side opposite
connector 130 embodying in the cylindrical structure formingproximal section 110 the shape of the ostium of the blood vessel branching off from the coronary bifurcation onto which it will be applied. - Furthermore,
proximal end 142 of the second distal section (140) is tapered at the other side of the second connector (150). It stretches forwards in its peripheral area opposite the second connector (150). This tapered portion (144) may also be determined by a plane that is inclined with reference toaxis 121, perpendicular to the plane of symmetry or, again, by a curved surface. - After expansion, as is illustrated in FIG. 4 for example, when the endoprosthesis is installed at the bifurcation of the two coronary arteries,
distal portion 113 with the corner cut off (115) ofproximal section 110 is fixed together harmoniously with the proximal (144) ofsection 140 of the endoprosthesis and ensures maximum coverage of the dilated coronary bifurcation area. - In this way, once in place, the whole of the grid of the bifurcated endoprosthesis (100) covers the proximal and distal portions of the two coronary branching arteries and the whole of the dilated bifurcation area.
- The first connector (130) preferably forms an integral part i.e. it is not joined onto
sections - In other words, the first connector (130) and
sections connector 130 is formed via machining. - The second connector (150) is also centred with reference to the plane of symmetry determined by
axes - However, whereas the first connector (130) extends in a direction that is parallel to
axes axes distal sections - The second connector (150) is preferably joined to
proximal ends sections - This aspect of the invention can, naturally, be embodied by a range of variants in that the second connector (150) could form an integral part with
distal sections connector 130 would be joined by means of, for example, laser welding to the distal end ofproximal section 110 and the proximal end ofdistal section 120. - In accordance with a particular embodiment, given as a non-exhaustive example,
bifurcated endoprosthesis 100 for the coronary artery conforming with this invention has the following dimensions: - the total length of
endoprosthesis 100 measured fromproximal end 112 ofproxinmal section 110 todistal end 123 ofdistal section 120 is of the order of 15 mm; - the diameter of
sections - the length of
proximal section 110 is of the order of 7.5 mm prior to expansion; - the length of
distal section 120 is of the order of 7 mm prior to expansion; - the length of
distal section 140 is of the order of 9 mm prior to expansion; - the length of
connector 130 is of the order of 0.5 to 1 mm; and - the diameter of
distal sections proximal section 110 is of the order of 3.5 mm. - A description now follows of the structure of the instrument fitted with a double asymmetric balloon conforming with this invention which is shown in FIG. 8 et seqq.
- Essentially, this instrument (200) comprises two balloons (210 and 230). The first balloon (210) is of a length consonant with its purpose of being positioned inside two approximately aligned sections (T1 and T2) of vessel V for treatment: main stem T1 and a branching vessel T2, situated one on either side of the bifurcation area respectively, or, again, of being positioned inside
proximal section 110 anddistal section 120 ofendoprosthesis 100. - As regards the second balloon (230), this is consonant with its purpose of being positioned in the second blood vessel (T3) branching off from the bifurcation.
Balloon 230 is preferably shorter thanballoon 210. As shown in the accompanying figures, the twoballoons axes - The main balloon (210) preferably incorporates a recess in its side (218) suitable for housing
proximal end 236 of the second balloon (230) as shown in FIG. 10. - Furthermore,
proximal portion 219 ofballoon 210 located upstream ofrecess 218 is preferably of greater diameter thandistal portion 217 of the same balloon located downstream ofrecess 218. - Each of the
balloons Tracers respective balloons Tracers internal tubes metallic guides centres axes balloons Tracers balloons - Balloons210 and 230 are prolonged a; their proximal ends 216 and 236 by, respectively,

Inflation tubes balloons common component 250 with two internal lumina (253 and 254) linked withinflation tubes Component 250 is, moreover, itself fitted at its proximal end (252) with two connection systems with fluid sources linked withlumina balloons - It is important that the above-mentioned connection systems communicating with, respectively,
lumina component 250 should allow the two balloons (210 and 230) to be expanded separately. - Balloons210 and 230 are preferably covered prior to use with a removable sheath (260).
Sheath 260 covers the fill length ofendoprosthesis 100, i.e. preferably a minimum of 15 to 20 mm.Sheath 260 is preferably linked at its proximal end to a wire (262) facilitating removal ofsheath 260 by pulling the saidwire 262.Wire 262 preferably passes throughcommon tube 250. -
Sheath 260 can, however, be omitted when the balloon system alone is used, i.e. withoutendoprosthesis 100. - The “Luer-Lock” connection systems shown in FIG. 12 are referred to as252. Furthermore, reference n° 270 in FIG. 12 labels a schematic inflation system comprising a pressure gauge (272) adapted for linkage to one of the connection system (252) with a view to dilating one of
balloons - Reference n°253 and n° 254 in FIG. 13 label the two feeder lumina linking
connection systems 252 withtubes sheath 260. - In accordance with a particular embodiment that is, naturally, non-exhaustive, asymmetric

balloons - the length of
common tube 250 ranges from approximately 110 to 115 mm; and - the outer diameter of the device with
balloons balloons feeder tubes endoprosthesis 100 andsheath 260. - The portion of
tubes - The portion of
tubes common portion 250, that is located upstream ofexits - This tube (224, 244 and 250) must be as hydrophilic as possible in order to be able to slide inside its carrier catheter or guiding catheter.
- It should be noted that
balloons common tube 250. - Guide-
wires tubes common section 250, as is seen in FIG. 11. Exit points 223 and 243 of guide-wires - A description now follows of the process for installing
endoprosthesis 100 using asymmetricdouble balloon 200 in accordance with this invention. - Prior to use, the unit combining the two balloons (210 and 230) and
bifurcated endoprosthesis 100 is protected by coveringsheath 260. This unit fitted withsheath 260 is firstly manoeuvred close to the bifurcation stenosis area. Its position is monitored using radio-opaque tracers - Once the balloon (210 and 230)/endoprosthesis (100) unit has arrived at the bifurcation, above-mentioned
sheath 260 can be withdrawn by pullingwire 262. - After
protective sheath 260 has been withdrawn, guide-wires Balloons proximal section 110 anddistal section 120 in the case ofballoon 210 and insidedistal section 140 in the case ofballoon 230, are still in a deflated state at this stage. Once it has been ascertained thatsections opaque tracers - To this end, the first asymmetric balloon (210), i.e. the longer balloon which facilitates expansion of the main structure (110) of the endoprosthesis and of
section 120, aligned with it, is preferably inflated first. Typicallyballoon 210 thus increases proximal portion 10 of the endoprosthesis to 3.5 mm anddistal portion 120 to 3 mm. - This is followed by inflation of the shorter balloon (230), whose
proximal end 236 fillsrecess 218 inballoon 210. Inflatingballoon 230 thus dilatessection 140 of the endoprosthesis. The proximal tapered shape ofsection 140 fits into the truncated form or form with its corner missing (115) of the main or proximal structure (110) of the endoprosthesis opposite and thus completely covers the ostial portion or bifurcation area of the coronary branching artery dilated and stented in the course of this procedure. - Once the bifurcated endoprosthesis has been deployed and installed, as shown in FIG. 7, balloons210 and 230 can be deflated and withdrawn.
- Balloons210 and 230 can be deflated and withdrawn simultaneously or separately, as appropriate, after being detached from the unit.
- It is advantageous for
balloons - This invention is not, of course, restricted to the particular embodiment described above but stems to any and all variants consistent with the idea embodied.
- In particular, the invention is no, limited to dilation of a bifurcation area in a coronary artery showing a lesion at the
bifurcation using endoprosthesis 100 and enmploying dilation ofballoons - A particular variant of the invention is one in which
balloon 210 may incorporate two portions (217 and 219), distal and proximal respectively, located on either side ofrecess 218 and having the same diameter. - During deployment,
balloon 230 may be inflated beforeballoon 210. - Furthermore, installation and dilation of
bifurcated endoprosthesis 100 may be envisaged using systems other than the double balloon structure illustrated in FIGS. 8 et seqq., and, in a corollary manner, the double-balloon system (200) may be used as a double balloon for coronary bifurcation lesion angioplasty not involving use of an endoprosthesis. - According to a variant of the invention, the
first balloon 210 is symetric about itslongitudinal axis 212. In other words therecess 218 is annular and symetric of revolution about thisaxis 212.
