Abstract

METHOD AND APPARATUS FOR REMOVING AND/OR ENLARGING
CONSTRICTED AREAS IN VESSELS CONDUCTING BODY FLUIDS

Abstract:
An apparatus and method for comminuting and/or eliminating constricted areas in vessels of all types whereby fissures and cracks in the vessel walls during the treatment of stenosis in blood vessels and also coronary obstruction are to be avoided. A treatment catheter is used which is equipped with two inflatable balloons which seal off a construction place in a vessel on both sides thereof whereby the degree of expansion of both balloons is externally regulatable. An inlet member for the supply of means dissol-ving the material of the constriction area or comminuting the same into smaller particles and an outlet member for the removal of the dissolved or comminuted material of the constriction place are provided in the walls of the treatment catheter within the area delimited by the two balloons. These inlet and outlet members are in communication with a channel accessible from the outside.

Description

~z~

Technical Fiel The present invention relates to a me-thod and apparatus for removing and/or enlarging constricted areas (stenoses) in vessels conducting body fluids.

Background Art German Auslegeschrift 1,069,g23, discloses an apparatus relating to at least two expandable balloons provided at a distance from ane another at the end on the vessel side of a treatment catheter. Each balloon is connected with a channel or duct accessible from the outside and can be inflated individually by external pressure. AEter the insertion of the treatment catheter into a urethra, the latter can be expanded or stretched by the inflation of the balloon. A stone forming a constricted place respec-tively closlng the urethra, is adapted to be enclosed between the balloons. In the expanded condition of the balloons, the treatment catheter is pulled out of the urethra and the s~one is removed thereby. However, this may lead to complications if the stone gets jammed in between a balloon 20 and the inner wall of the urethra, Eor example, when being pulled out. The stone then has to be seized anew correctly within the area delimited by the balloons by a change of the expansion of the balloons. When pulling out the catheter, the entire urethra is thereby sub~ected to a s-trong stretching, starting from the constricted place and in particular the inner wall is stressed by strong friction pressures. This may lead to cracks or detachments at least of the inner wall of the urethra.

Furthermore, C,erman Offenlegungsschrift 3,02~,089 discloses 30 use of a treatment catheter for the enlargement ofconstricted places in the arterial system at the end of which is attached a balloon adap-ted X

L~

to expand its circumference to a certain dimension. This balloon is placed in the area of the constriction and is fille~ with a liq~lid bv way OI a catheter so that the tissue causing the constriction is pressed into the wall of the blood vessel and remains there. Frequently during the dilatation, cracks in the intima of the innermost wall of the vessel system cannot be avoided. Furthermore, the danger exists that the inner vessel layers become detached in part and obstruct the free interior space of the blood vessel, as a result of ~hich thrombi and ischemia of the organs could result in the vessel system which are supplied by the respective blood vessel. Thus, for example, a coronary obstruction may result at the coronary arteries as a result of inadequate blood supply.

Summarv of the Invention The object underlying the present invention resides in the 1~ creation of an apparatus, simple in construction, economically producible and reliable in operation, with the aid of which the constrictions of any vessels conducting body fluids can be so reduced and eliminated independentl~T of their spacial arrangement or extent in the vessel system that it will not lead to fissures or "O cracks in the vessel wall. With the application of the apparatus according to the present invention in blood vessels, the supply of the organ or organs located downstream of the constricted area is also to be assured during a treatment of the constricted area which lasts for longer periods of time and therewith the danger of a coronary "~ obstruction can also be excluded in those cases.

The underlying problems are solved according to the present invention in that within the area delimited by the two balloons at least one opening is provided in the wall of the treatment catheter ~2~

which Eorms respectively from the orifice of at least one inflow or discharye channel accessible from the outside in such a manner -that means can be supplied from the outside through this or -these inflow or discharge channels into the limited area, especially a material dissolving the constric-tion material, comminuting the same into small particles or softening the same, or a substance, especially dissolved or comminuted constricted area material, can be conducted toward the outside of the limited area through respec-tively these supply or discharge channels.
By the arrangement of an opening between the two balloons and the connection thereof to a channel accessible from the outside, each constricted location can be eliminated in a protected manner within a relatively short period of time by an intentional dissolution or comminution of material of the constricted areas and by one or several subsequen-t flushing operations of the constricted location. Substantially no disadvantageous side effect occurs thereby as a result of vessel stretching or expansion because the same is undertaken 20 only within the healthy area of the vessel and more particularly only at two narrow locations thereof. The apparatus according to the present invention can therefore be applied in all those cases in which the constricted location is formed by substances which are adapted to be dissolved or comminuted.
By softening the material at the constricted location, its removal from the constricted location becomes particularly nonproblematical because the danger of damaging the vessel walls are completely eliminated in this case by reason of the consistency of the material of the constricted location.
According to an advantageous construction of the presen-t invention, a supply channel may additionally be provided. At the same time, a sufficient supply of fluid throuyh the supply channel to ~Q~

the organ located downstream thereof is assured during the treatment oE the constricted area. It is particularly advantageous that treatmellt liquids, possib:Ly also in stronger concentrated Eorm, can be made effective over periods of time adapted to be selected at will on the material of the constricted area by means of the invention within predetermined areas oE vessels conducting body fluids within an area that can be delimited.
These and other objects, features and advantages of the present invention will become more apparent from the follow-ing description when taken in connection with the accompany-ing drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.

Detailed Description of the Invention -Referring now to the drawings wherein like reference numerals are used throughout the various views to designate like parts, the treatment catheter 1 is inserted into a blood vessel 3 by a guide catheter 2. The treatment catheter 1 projects beyond the guide catheter 2 to the extent that the balloons 4 and 5 arranged on the treatment catheter 1 such that the constricted area 6 or stenosis is enclosed there-between ahead of the end of the guide catheter 2. The stenosis 6 is customarily formed of a sponge-like calcified and fatty tissue which is indicated in the drawing by a cross~section marked with crisscrossing. In case the tissue " r ~2~6'~'~

7 closes off the passage of the blood vessel 3 completely or nearly completely, the treatment catheter 1 or initially another instrument is forced through the same. Otherwise, the treatment catheter 1 is guided through the existing opening of the constriction 6 so that the balloon 4 in the inflated condition 4' seals off the constriction 6 on the backside thereof and the balloon 5 in the inflated condition 5' seals off the constriction 6 on the front side thereof.
Thus, the blood vessel 3 is tightly sealed all around on both sides of the constricted area 6.
The expansion or inflation of the balloons 4 and 5 can take place by a gas or a liquid medium. The latter can be admitted and discharged from the outside by way of the inlet-outlet nozzles 8 and 9 and by way of a pressure duct or channel 10, whereby the quantity and pressure medium are controllable. In order that the supply of Eluid of the organ or organs located downstream is assured, in particular, during longer treatment periods, during the treatment of constricted places 6 in blood vessels notwith-2Q standing the closing oEf on both sides of the constrictedplace 6, an additional supply channel 11 is provided. It represents a type of "bypass line" to the sealed off constricted area. The supply channel 11 is preferably arranged coaxially to the treatment catheter 1. However, deviating therefrom, it may also be built in or built on in another position or in th~ form of a multiple channel.
Blood and other fluids, may flow in by way of this supply channel 11, preferably under excess pressure from outside, with the aid of an overflow channel, out of the blood circulation, located ahead of the blockage. As a result thereof, sufficiently long operating periods are available without the danger of a coronary obs~ruction.

,, In order that only calcified and fatty tissue 7 of the constriction is attacked, but not the inner skins of -the blood vessel 3, a solution of chemical subs-tance is pumped through the inlet channel 12, having -the inlet section A into the space containing the constricted area tissue 7. The chemical substance is able to dissolve the -tissue 7.
Digestive enzymes or similar substances are suitable examples of such chemical substances.
For other applications, such as the treatment of gall or kidney deposits or stones, other substances may be used such as dissolving acids.
For the removal of dissolved or comminuted particles and for softening the treatment time, a continued c~rculatory flushing is advantageous. This is assured by way of a return channel 13 with the outlet part B. In principal, however, it is also possible to supply the means dissolving the material 7 at the constriction or comminuting the same into smaller particles by way of a single channel and to discharge or remove the dissolved or comminuted constriction material 7 alternately by way of the same channel. Figures 7, 8 and 11 illustrate such a construction which will be described more fully hereinafter. Of course, the inlet channel 12 may also be used as return channel and the return channel 13 as inlet channel.
Depending on demand, the number of in and flow and return flow channels may also be increased.

In order to be able to match the size of the blockage place to the expansion of the tissue 7, it is of advantage if the balloon 5 is not arranged rigidly -- as indicated in Fig. 1 -- but is arranged displaceably 30 on the treatment catheter 1. Such an embodiment is illustrated in Figures 3 and 4. The balloon i5 thereby cured on a slider 14 which is movable to and fro from outside, preferably, with X

~04s~

the aid of a more rigid synthetic fiber wire - preferably, pearl on wire 15 or the like. Synthetic Eiber wire 15 may thereby be guided in a channel 16 which is accommodated in an elongated raised portion 17 of the treatment catheter 1 serving sirnultaneously for the guidance of the slide member 14, that is, practically in its wall reinEorcement.
At the same time, the infla~ion medium may be supplied and discharged through this channel 16 and the pressure thereof can be regulated from the outside.
In order that the gap between the slide member 14 and the outer wall of the treatment catheter 1 is sealed off completely satisfactorily, a sealing sleeve 18 is provided at least at the side facing the constriction 6, which by a particular configuration of the balloon 5 additionally contributes to the effective seal at this sealing place.
Reference numeral 19 designates the nozzle. Gaseous or liquid medium for the expansion of the displaceable balloon 5 is supplied and discharged through the nozzle.
In lieu of the hose-shaped channels 10, 12 and 13 fed and secured at the wall parts of the treatment catheter 1, the interior space of the treatment catheter 1 can also be subdivided correspondingly by longitudinal partition walls 20 (Fig. 2 and Fig. 5) so that chambers 21 result through which, depending on n~ed, the corresponding medium can be conducted.
Furthermore, it is advantageous in some cases -especially with the application of longitudinal partition walls 20 - to provide the walls of the treatment catheter 1 with perforations 23 in lieu of the provision of inlet ~
outlet nozzles 8 and 9 respectively of the nozzles A and B
at the ends of the channels 12 and 13. At these locations, whereby these perforations, as can be seen from Fig~ 5 and 3~Z~)9L6'~ ~

Fig. 6, will result only after the breaking open of intentional breakage places 22 so that the length of the perforated catheter part can be adjusted only prior to the interaction corresponding to ~he si~e of the constriction to be treatedO
Fig. 7 and Fig. B illustrate a fur~h,er embodiment according to the present invention with the single longitudinal partition wall 20. Thus, the treatment catheter 1 is subdivided into two channels. One channel is constructed as combined pressure and supply channel 24. The other channel is constructed as a combined inlet and discharge channel 25 for ~he constriction 6. Channel 24 includes within the aréa of each balloon 4 and 5 openings 8 and 9 and at the end of the treatment catheter 1 on the side of the vessel, a discharge opening 27. The other channel includes within the delimited area an inlet ou~let opening A/B. Because of its possible smaller diameter, this treatment catheter is particularly suited for small vessel cross-sections. On one hand, it is achieved as a result of a li~uid pressure produced in the channel 24 by means of a liquid externally supplied, especially of a supply liquid for organs located down-stream, for example, blood can be supplied at the same time the balloons 4 and 5 can be expanded. As a result thereof, the isolated area about the constriction 6 can be sealed off on both sides. The liquid then leaves under pressure through the discharge opening 27~ On the other hand, the substance dissolving the material of the constriction can be pumped into the constriction 6 through the channel 25 either continuously or intermittently and 3~ subsequently dissolved material of the constriction area can be withdrawn together with the remaining substance.

~L2~

~s a result thereof~ the aimed at effect becomes possible together with a treatment catheter 1 which can be manufactured in a simple manner, whereby the cross section thereof can be kept very small.
According to a further advantageous c:onstruction of ~he present invention~ one or the other of balloons 4 or 5 may be of a construction which has a more elastic casing or wall than the other. In the embodiment according to Fig. 7 and Fig. 8, this is the balloon 4. It is possible thereby to so adjust and regulate the pressure that both balloons 4 and 5 seal off and, for example, during the withdrawal of the substances out of the delimited area the balloon 4 still seals off whereas the balloon 5 no longer forms an eEEective seal as shown in Fig. 7. It becomes possible thereby to also utilize th~ guide catheter 2 for flushing or suction because with such a pressure adjustment the constriction 6 is also accessible from the side of the guide catheter 2.
Appropriately, the balloons 4 and 5 of the apparatus according to the present invention may be so constructed that they assume a predetermined shape and size and then no longer grow in size even with the application of a considerably higher pressure.
In the advantageous embodiments of the present invention illustrated in Figs. 9, 10 and 11, the balloon 5 which is located further removed from the end 25 on the side of the vessel of the treatment catheter 1, is provided on the end of an area limiting catheter 28 which is slidably arranged on the treatment catheter 1. The area limiting catheter 28 is provided with a pressure channel 29 which is preferably integrated into the wall of the area limiting catheter 28 and which terminates in an ,~

opening 30 provided inside of the balloon 5. ~y a displacement of the area limiting catheter 28 the length of the limited area can be selected corresponding to the requirements and can be sealed off or opened again by the separate expansion possibility of the balloon 5. Also in this case, a space may be advantageously left between the treatment catheter 1 and the area limiting catheter 28 and this space can be used for purposes oE flushing or suc~ion.
For purposes of a very compact type construction, one or several notches 31 may also be provided for that purpose at the inner wall of ~he area limiting catheter 28 and/or notches 32 at the outer wall of the treatment catheter 1, as illustrated in Fig. 10 and Fig. 11. In order to achieve thereby larger cross-sections for lOa throughflow, the notches 31 o~ the limiting area catheter 28 may thereby be arranged opposite the notches 32 of the treatment catheter 1. Also with this constructive solution according to the present invention a single longitudinal partition wall 20 may be provided in the treatment catheter 1 -- as shown in Fig. 11 -- and the treatment catheter 1 may be provided with an opening as described by reference to Fig. 7 so that the effects described in connection therewith are also attainable. The apparatus according to Figures 9, 10 and 11 may further include a guide catheter 2 (not shown).
A catheter according to the present invention for the treatment of constricted locations can be used with all types of vessels conducting body fluids, that is, with all types of blood vessels or other vessels conducting other liquids, such as cerebral spinal channels or also with larger lymph ducts.
Further fields of application -- in addition to the main application areas of the treatment of constrictions in blood vessels -- are for example the treatment of constrictions in the bile duct, in the pancreas duct or in the cerebral spinal duct.
It is also possible with the present invention to bring chemical substances in high or even more highly concentrated ~orm to the vessel areas with the aim to initiate from these vessel areas capillary vesicles starting revascularization.
In particular, the materials, namely angiotropine which are isolated out of white blood corpuscles may be considered for stimulating revascularization.

~l2~6~

The dissolving material can be an enzyme, preferably a digestive enzyme, acid or alkaline. Nitric acid and sodium hydroxide can be used as the dissolving material. The reaction time Eor the dissolving material on the con-stricted area can be limited by inhibiters, such as enzyme blockers, ne~tralizing acids or lyes to a predetermined time duration. Thus, the constricted area material can be dissolved, softened or comminuted into smaller particles prior to circulatory flushing to remove the material~ The constricted area material can be removed as a whole after softening upon the withdrawal of the treatment catheter.
The latter can occur with reduced pressure of one or both balloons.
The constriction treatment with the catheter according to the present invention may be undertaken in several stages, possibly with the use of di~ferent treatment media and/or different concentrations of the treatment media.
The materials used in the fabrication of the apparatus of the present invention, namely, the catheter and its functional components, are conventional.
While we have shown and described several embodiments in accordance with the present invention, it is understood that the same is not limited thereto but is susceptible of numerous changes and modifications as known to those skilled in the art and we therefore do not wish to be limited to the details shown and described herein but intend to cover all such changes and modifications as are encompassed by the scope of the appended claims.
