Abstract
All metal stent grafts and covered stents having either a single structural supporting stent member with concentrically positioned graft members on the luminal and abluminal surfaces of the stent member or a single graft member with concentrically positioned structural supporting stent members on the luminal and abluminal surfaces of the graft member are provided.
Claims35
A medical device, comprising:
- (a) A generally tubular structural support member having luminal and abluminal wall surfaces thereof and being comprised of at least one of a metallic and pseudometallic material;
- and
- (b) At least one of a plurality of generally tubular cover members comprised of at least one of a metallic and pseudometallic material, the at least one of a plurality of generally tubular cover members being concentrically adjacent both the luminal and abluminal wall surfaces of the generally tubular structural support member.
The medical device according to 2, wherein the thin metallic film is 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, chromium-cobalt alloy, zirconium-titanium-tantalum alloy, nickel-titanium alloy, and stainless steel.
A covered stent device, comprising:
- (a) A diametrically expandable stent;
- and
- (b) At least one cover member consisting essentially of a thin metallic film having a plurality of openings passing therethrough, and concentrically adjacent at least one of a luminal and an abluminal wall surface of the diametrically expandable stent.
A medical device, comprising:
- (a) A generally tubular member having luminal and abluminal wall surfaces thereof and being comprised of at least one of a metallic and pseudometallic material;
- and
- (b) At least one of two structural support members, a first structural support member being positioned concentrically adjacent a luminal wall surface of the generally tubular graft member and a second structural support member being positioned concentrically adjacent an abluminal wall surface of the generally tubular graft member.
The medical device according to 27, wherein the thin metallic film is 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, chromium-cobalt alloy, zirconium-titanium-tantalum alloy, nickel-titanium alloy, and stainless steel.
