- This invention relates to improved apparatus suitable for stent delivery and implantation.
- Stents are implantable devices which are placed within body lumens and the like, such as blood vessels. Stents are typically tubular in form, the diameter of which can be increased for implantation. They maybe made of plastic or metal. Stents are usually introduced for implantation percutaneously by means of a catheter and the diameter of the stent is increased by inflation of a balloon on the catheter.

- This invention relates to improved apparatus suitable for stent delivery and implantation.
- Stents are implantable devices which are placed within body lumens and the like, such as blood vessels. Stents are typically tubular in form, the diameter of which can be increased for implantation. They maybe made of plastic or metal. Stents are usually introduced for implantation percutaneously by means of a catheter and the diameter of the stent is increased by inflation of a balloon on the catheter.
- In one aspect, this invention relates to an improvement in the stent delivery system described in U.S. Pat. No. 4,950,227 to Savin et al., entitled “Stent Delivery System” and issued on Aug. 21, 1990. This patent is incorporated herein in its entirety by reference.
- That patent discloses a stent delivery system in which a catheter carries, on its distal end portion, a stent which is held in place around the catheter prior to and during percutaneous delivery by means of one and preferably two sleeves.

- FIG. 9 is a schematic showing of a balloon of modified construction according to the invention;
- FIG. 10 is an axial cross-section similar to FIG. 1 showing the balloon of FIG. 9 on a catheter with retractable sleeves, and
- FIG. 11 is a schematic view in fragment of another embodiment of the invention.
- A stent-carrying balloon catheter is illustrated generally in FIG. 1 and designated by the
reference numeral 10. Thecatheter 10 is operatively disposed in a body conduit defined bywalls 11 and includes anelongate cannula 12 having adistal end 14 and a proximal end (not shown). -
Catheter 10 includes a balloon 16 (inflated) having adistal end 18 and aproximal end 21. Acentral wall 27 is disposed betweenend wall central region 30 ofballoon 16. - In this embodiment the
end walls central wall 27 ofballoon 16 which is relatively thin and relatively large in diameter. - A pair of transition walls or
cones stent 36 is shown onballoon 16 being expanded by the dilated balloon. - Referring to FIGS. 2 and 3, the
cones cone portions catheter cannula 12 to encompass theends 36 a and 36 b respectively of the stent thus securing it to the catheter. - Upon inflation of
balloon 16, folds 32 a and 32 b open to a configuration similar to that shown in FIG. 1 to release the stent for expansion by the balloon. - Referring to FIG. 4, a
stent delivery system 10 includes aballoon catheter 12 having aballoon 16 fixed to the catheter for remote inflation as is known in the art. The catheter includes anelongate cannula 46 and may includemarker bands 44.Balloon 16 is shown in a somewhat contracted state. Astent 36 is positioned aboutballoon 16 oncatheter 12 and held by two overlying retaining sleeves, a proximal one 40 and a distal one 42. - Stent36 may be of any known type. In this instance for example it may be a balloon expandable stent of stainless steel, such as the known types which are cut or etched from hypotubes.
-
Sleeves catheter 12 as by an adhesive (not shown). The sleeves overlapstent 36 at each of the stent ends ormargin 36 a and 36 b as shown. Additionally, further securement ofstent 36 is provided byballoon folds 32 a and 32 b similar to those shown in FIGS. 2 and 3. -
Sleeves stent 16 is provided byballoon folds 32 a and 32 b similar to those shown in FIGS. 2 and 3. - Referring to FIGS. 5, 6,7 and 8, the
stent delivery system 10 of FIG. 4 is inserted percutaneously by known technique into a body lumen or the like. As the stent is positioned (FIG. 2),balloon 16 is expanded (FIGS. 6 and 7). During balloon expansion,stent 36 is also expanded and sleeves 40 and 42 deform elastically while balloon folds 32 a and 32 b open to release the stent. The balloon is then deflated by standard technique andcatheter 12 withsleeves stent 36 implanted (FIG. 8). - In some instances, only one sleeve may be provided at one end in the system. Also, only one fold may be provided in the balloon at one end. Preferably, the fold(s) are in the end regions of the balloon but could be located anywhere to accommodate the size stent used relative to the balloon length used.
- Referring now to FIG. 9, a
balloon 16 of modified construction according to the invention is shown.Balloon 16 includes acentral body portion 30 of a nominal size, distal catheter attachment ends 18 and 21, andcone portions Cone portions body 30, than thenominal body 30 size. - A purpose of this construction modification in the balloon is to facilitate sleeve retraction as is shown in FIG. 10. As can be seen from the Figure, when
balloon 30 begins to inflate, theenlarged cones sleeve stent 36 for expansion upon further inflation of the balloon. - It is contemplated within the purview of this invention that the balloon, particularly in the region of the cones, may be physically modified so as to change the mechanical characteristics of the balloon in order to facilitate folding of the balloon. For example, this may be accomplished by forming slits or other apertures in those regions of the balloon. Sealing would be accomplished by the balloon fold or by covering by the sleeves. Such apertures might be formed in the balloon as made or formed in it later. For example, when the stent is crimped to the balloon, the stent ends maybe utilized to form apertures in the balloon material.
- Referring now to FIG. 11, which is a fragment schematic of a catheter system similar to those of the preceding Figures, a modified balloon construction is shown in which the
stent 36 is positioned within a raisedend 16 a and 16 b ofballoon 16. Optionally, adam 50 may be included as is known in the art. The balloon will preferably include raised end portions at both ends as shown. However, only one end, preferably the distal end 16 a, could be raised. The raised relationship may be slitted by forming it in the balloon similar to the construction shown in FIG. 9. Rotating sleeves may be optionally used in this embodiment. - The above Examples and disclosure are intended to be illustrative and not exhaustive. These examples and description will suggest many variations and alternatives to one of ordinary skill in this art. All these alternatives and variations are intended to be included within the scope of the attached claims. Those familiar with the art may recognize other equivalents to the specific embodiments described herein which equivalents are also intended to be encompassed by the claims attached hereto.
