Compliant implantable medical devices and methods of making same
First Claim
1. An implantable medical device, comprising:
- a. a body member comprising a film selected from the group consisting of vacuum-deposited metallic and vacuum-deposited pseudometallic materials and 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, wherein said plurality of microperforations further comprise a first row of microperforations and a second row of microperforations, wherein the first row of microperforations is offset from the second row of microperforations with an end of an microperforation in the first row being laterally adjacent to an intermediate section of a microperforation in the second row.

Abstract
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.

17. An implantable medical device, comprising:
-
a. a body member comprising a film selected from the group consisting of metallic and pseudometallic materials and having a first surface, a second surface, and a thickness intermediate the first surface and the second surface, wherein the film has controlled heterogeneities; and
,b. a plurality of microperforations passing through the thickness of the body member and communicating between the first surface and the second surface, wherein said plurality of microperforations further comprise a first row of microperforations and a second row of microperforations, wherein the first row of microperforations is offset from the second row of microperforations with an end of an microperforation in the first row being laterally adjacent to an intermediate section of a microperforation in the second row.

18. An medical graft member, comprising:
-
a. a tubular body member comprising a self-supporting film selected from the group consisting of metallic and pseudometallic materials and 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 and the plurality of microperforations are patterned to create a plurality of folding regions to permit folding of the medical graft member along the folding regions.
