Stretchable stent and delivery system
First Claim
1. A medical device comprising:
- a tubular implant having first and second ends and extending along a longitudinal axis, the first end of the implant including a tab; and
an implant delivery system comprising a catheter including a retainer configured to secure the first end of the implant to the catheter, wherein the retainer is configured to receive the tab and defines one or more inclined surfaces forming an oblique angle with the longitudinal axis of the implant such that the one or more inclined surfaces faces the tab when the tab is received within the retainer.

Abstract
An implant delivery catheter enables permanent modification of the implant length in the vicinity of the treatment site prior to radial expansion thereof. The implant is releasable carried between inner and outer tubular members of the delivery catheter which, upon repositioning relative to one another using an actuator mechanism, impart any of tensile, compressile or torquing forces to the implant causing permanent modification of the implant length. In one embodiment, the circumference of the implant is substantially similar both before and after modification of the implant length. In another embodiment, the implant includes a plurality of strut sections interconnected by bridges which are capable of the deformation along the longitudinal axis of the implant.

17. A medical device comprising:
-
a tubular implant having a circumference, first and second ends, and having an initial length L1 along a longitudinal axis, at least one of the first end or the second end of the implant including a tab; and an implant delivery system comprising a catheter comprising an outer tubular member disposed about an inner tubular member, the first end of the implant secured to the outer tubular member via a first retainer, and the second end of the implant secured to the inner tubular member via a second retainer such that changes in the relative positions of the outer tubular member and the inner tubular member change the initial length L1 of the implant to a modified length L2 along the longitudinal axis, the initial length L1 being an un-stretched length of the implant, and L2 being a maximum stretched length of the implant, and wherein at least one of the first retainer or the second retainer is configured to receive the tab and defines one or more inclined surfaces forming an oblique angle with the longitudinal axis of the implant such that the surface faces the tab when the tab is received within the retainer. - View Dependent Claims (18)

19. A method comprising:
-
securing a first end of a tubular implant to an outer member of a catheter, the tubular implant having first and second ends and extending along a longitudinal axis, and the first end of the implant including a tab, wherein the outer member comprises a retainer configured to receive the tab and defines one or more inclined surfaces forming an oblique angle with the longitudinal axis of the implant, wherein securing the first end of the tubular implant to the outer member comprises introducing the tab in the retainer such that the surface faces the tab; and changing a relative position of the outer member with respect to an inner member of the catheter to change an initial length L1 of the implant to a modified length L2 along the longitudinal axis. - View Dependent Claims (20)
