Actively Controllable Stent, Stent Graft, Heart Valve and Method of Controlling Same
First Claim
1. A surgical implant, comprising:
- a self-expanding stent of a shape-memory material set to a given shape, the self-expanding stent having a wall with at least one first portion having a first wall thickness and at least one second portion having a second wall thickness greater than the first wall thickness, the at least one second portion defining a key-hole shaped longitudinal drive orifice; and
a selectively adjustable assembly at the self-expanding stent, having adjustable elements, and being operable to force a configuration change in at least a portion of the self-expanding stent, the adjustable elements having a part rotatably disposed within the longitudinal drive orifice.

Abstract
Sealable and repositionable implant devices are provided to increase the ability of endovascular grafts and valves to be precisely deployed or re-deployed, with better in situ accommodation to the local anatomy of the targeted recipient anatomic site, and with the ability for post-deployment adjustment to accommodate anatomic changes that might compromise the efficacy of the implant. A surgical implant includes a self-expanding stent of a shape-memory material set to a given shape. The stent has a wall with a portion having a first thickness and a second portion having a thickness greater than the first. The second portion defines a key-hole shaped longitudinal drive orifice. The implant includes a selectively adjustable assembly having adjustable elements and being operable to force a configuration change in at least a portion of the self-expanding stent. The adjustable elements have a part rotatably disposed within the longitudinal drive orifice.
