Surgical implant devices and methods for their manufacture and use

摘要

Sealable and repositionable implant devices are provided with one or more improvements that increase the ability of implants such as endovascular grafts to be precisely deployed or re-deployed, with better in situ accommodation to the local anatomy of the targeted recipient anatomic site, and/or with the ability for post-deployment adjustment to accommodate anatomic changes that might compromise the efficacy of the implant. A surgical implant includes an implant body and a selectively adjustable assembly attached to the implant body, having adjustable elements, and operable to cause a configuration change in a portion of the implant body and, thereby, permit implantation of the implant body within an anatomic orifice to effect a seal therein under normal physiological conditions.

主权项

1. A surgical implant, comprising:
an implant body; and a selectively adjustable, circumferentially expandable and contractible collar attached to a portion of the implant body and having at least one torque transmission shaft that, when rotated, causes either an expanding or contracting configuration change in the collar and the portion of the implant body and, thereby, permits implantation of the implant body within an anatomic orifice to effect a seal therein under normal physiological conditions.
