COMPLIANT IMPLANTABLE MEDICAL DEVICES AND METHODS OF MAKING SAME

摘要

Implantable medical grafts fabricated of metallic or pseudometallic films of biocompatible materials having a plurality of microperforations passing through the film in a pattern that imparts fabric-like qualities to the graft or permits the geometric deformation of the graft. The implantable graft is preferably fabricated by vacuum deposition of metallic and/or pseudometallic materials into either single or multi-layered structures with the plurality of microperforations either being formed during deposition or after deposition by selective removal of sections of the deposited film. The implantable medical grafts are suitable for use as endoluminal or surgical grafts and may be used as vascular grafts, stent-grafts, skin grafts, shunts, bone grafts, surgical patches, non-vascular conduits, valvular leaflets, filters, occlusion membranes, artificial sphincters, tendons and ligaments.

主权项

1. An implantable medical device, comprising: a. a body member comprising a film having a first surface, a second surface and a thickness intermediate the first surface and the second surface; and b. a plurality of microperforations passing through the thickness of the body member and communicating between the first surface and the second surface, whereby said plurality of microperforations impart compliance to the body member.
