Surgical implant devices and methods for their manufacture and use
First Claim
1. An assembly, comprising:
- an implant body having a stent member and an adjustment member, wherein the stent member is circumferentially expandable and contractible, the adjustment member is coupled to the stent member, and actuating the adjustment member results in circumferential expansion or contraction of the stent member; and
a delivery apparatus having a rotatable shaft and a locking mechanism coupled to an end portion of the shaft, wherein the shaft is configured to actuate the adjustment member of the implant body upon rotation of the shaft, and the locking mechanism is configured to selectively couple the shaft to the adjustment member of the implant body.

Abstract
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.

9. An assembly, comprising:
-
a stent member, wherein the stent member is circumferentially expandable and contractible; an adjustment member, wherein the adjustment member is coupled to the stent member and configured for circumferentially expanding and contracting the stent member; a rotatable shaft; and a locking mechanism coupled to the shaft and movable between a lock configuration and a release configuration, wherein the locking mechanism is configured to engage the adjustment member such that axial movement of the shaft results in corresponding axial movement of the adjustment member when locking mechanism is in the lock configuration, and wherein the locking mechanism is configured to disengage the adjustment member such that the shaft can move axially relative to the adjustment member when the locking mechanism is in the release configuration. - View Dependent Claims (10, 11, 12, 13)

14. An assembly, comprising:
-
a radially expandable and contractible stent member; an adjustment member coupled to the stent member and having a rotatable portion, wherein rotating the rotatable member in a first direction relative to the stent member radially expands the stent member, and rotating the rotatable member in a second direction relative to the stent member radially contracts the stent member; a rotatable shaft; and a locking mechanism coupled to the shaft and configured to releasably couple the shaft to the adjustment member of the implant body, wherein the locking mechanism includes a lock configuration and a release configuration, wherein, in the lock configuration, axial movement of the shaft results in corresponding axial movement of the adjustment member, and, in the release configuration, the shaft can move axially relative to the adjustment member. - View Dependent Claims (15, 16, 17, 18)
