Abstract

Implantable medical grafts (10) fabricated of metallic or pseudometallic fil ms of biocompatible materials having a plurality of microperforations (20) 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, shunts, bone grafts , surgical patches, non-vascular conduits, valvular leaflets, filters, occlusi on membranes, artificial sphincters, tendons and ligaments.

Claims (9)

1. An implantable medical graft, 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; and b. a plurality of microperforations passing through the thickness of the body member and communicating between the first surface and the second surface.
2. The implantable medical graft according to Claim 1, wherein the film is made of a metallic material selected from the group consisting of titanium, vanadium, aluminum, nickel, tantalum, zirconium, chromium, silver, gold, silicon, magnesium, niobium, scandium, platinum, cobalt, palladium, manganese, molybdenum and alloys thereof.
3. The implantable graft according to Claim 1, wherein the each of the plurality of microperforations is capable of undergoing geometric deformation.
4. The implantable graft according to Claim 1, wherein the plurality of microperforations are arrayed in at least one pattern that imparts at least one of compliance and pliability to the body member.
5. The implantable graft according to Claim 1, wherein the plurality of microperforations is arrayed in at least one pattern sufficient to permit dimensional change of at least a portion of the device.
6. The implantable graft according to Claim 5, wherein the dimensional change comprises at least one of elastic, plastic, shape memory and superelastic compliance.
7. The implantable medical graft according to Claim 1, wherein the body member further comprises a tubular member, the first surface further comprises a luminal surface of the tubular member and the second surface further comprises an abluminal surface of the tubular member.
8. The implantable medical graft according to Claim 1, wherein the body member further comprises a generally planar member.
9. The implantable medical graft according to Claim 1, wherein the plurality of microperforations each further comprise a generally co-planar tri-leg configuration.
