1. A endograft implant, comprising:
- a. a tubular implant body comprising an elastic proximal end, an elastic distal end, and an implant lumen, wherein the elastic proximal end and the elastic distal end each comprise a sealable circumferential collar;
b. a distal variable sealing device contained within the distal sealable circumferential collar, the distal variable sealing device suitable for reversibly varying the diameter of the distal sealable circumferential collar;
c. a proximal variable sealing device contained within the proximal sealable circumferential collar, the proximal variable sealing device suitable for reversibly varying the diameter of the proximal sealable circumferential collar;
d. a distal control lead releasably connected to the distal variable sealing device for reversibly varying the diameter of the distal variable sealing device;
e. a proximal control lead releasably connected to the proximal variable sealing device for reversibly varying the diameter of the proximal variable sealing device; and
f. a plurality of retractable retention tines contained within the distal variable sealing device and the proximal variable sealing device, wherein the retractable retention tines are exposed or withdraw upon varying the diameter of each variable sealing device.

Abstract
This disclosure is directed toward sealable and repositionable implant devices that 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.

16. A endograft implant system, comprising:
-
a. An implant delivery catheter comprising an external end, an internal end, and a lumen, suitable for placement into an anatomic space comprising an internal wall, the implant delivery catheter further comprising a sheath which is openable or removable at the internal end; and b. a compressed or folded endograft implant contained within the implant delivery catheter lumen, the endograft implant comprising; i. a tubular implant body comprising an elastic proximal end, an elastic distal end, and an implant lumen, wherein the elastic proximal end and the elastic distal end each comprise a sealable circumferential collar; ii. a separate variable sealing device contained within each of the distal sealable circumferential collar and the proximal sealable circumferential collar, each variable sealing device suitable for reversibly varying the diameter of the sealable circumferential collar in which it is contained; iii. a separate control lead releasably connected to each of the distal variable sealing device and the proximal variable sealing device for reversibly varying the diameter of the variable sealing device to which it is releasably connected; and iv. a plurality of retractable retention tines contained within each variable sealing device, wherein the retractable retention tines are exposed or withdraw upon varying the diameter of each variable sealing device. - View Dependent Claims (17, 18)
