Claims
- 1. An implantable valvular prosthesis having a stent body at least partially covered by a graft member, at least one biasing art projecting from the stent body into a central lumen of the stent body member and at least one valve flap member coupled to the biasing art, the improvement comprising: the at least one valve flap member being comprised of a biocompatible material selected from the group consisting of metals and pseudometals.
- 2. The implantable valvular prosthesis according to claim 1, wherein the biocompatible material further comprises a plurality of layers.
- 3. The implantable valvular prosthesis according to claim 1, wherein the biocompatible material 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 , such as zirconium-titanium-tantalum alloys, nitinol, and stainless steel.
- 4. The implantable valvular prosthesis according to claim 1, wherein the graft member further comprises a biocompatible metal film.
- 5. The implantable valvular prosthesis according to claim 2, wherein the graft member further comprises a biocompatible metal film.
- 6. The implantable valvular prosthesis according to claim 4, wherein biocompatible metal film of the graft member 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, such as zirconium-titanium-tantalum alloys, nitinol, and stainless steel.
- 7. An implantable valvular prosthesis having a stent body at least partially covered by a graft member, at least one biasing arm projecting from the stent body into a central lumen of the stent body member and at least one valve flap member coupled to the biasing arm, the improvement comprising: the at least one valve flap member being comprised of a biocompatible film fabricated of a material selected from metals and pseudometals.
- 8. The implantable valvular prosthesis according to claim 7, wherein the biocompatible pseudometallic film further comprises a plurality of film layers at least one layer being a pseudometallic material.
