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.
