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 plurality of key-hole shaped longitudinal drive orifices, wherein the key-hole shaped longitudinal drive orifices have openings facing radially outwards or radially inwards; 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 each having a part rotatably disposed within a respective key-hole shaped 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.
