Abstract

The invention relates to a medical valve implant for implantation in the animal body and/or human body, comprising a support frame that includes a first end and a second end, which are disposed on opposite ends of the support frame in a main extension direction of support frame. According to the invention, one or more auxiliary devices that are required for implantation and/or that serve a functional purpose for a limited time and are intended to remain in the body after implantation are formed, at least in sections, of a material that can decompose in the body.

Claims

1. A medical valve implant for implantation in the animal body and/or human body, comprising a support frame that includes a first end and a second end, which are disposed on opposite ends of the support frame in a main extension direction of the support frame, characterized in that one or more auxiliary devices that are required for implantation and/or that serve a functional purpose for a limited time and are intended to remain in the body after implantation are formed, at least in sections, of a material that can decompose in the body.

2. The medical valve implant according to claim 1, characterized in that one or more auxiliary devices include at least one positioning device that is intended to remain in the body after implantation and is formed, at least in sections, of a material that can decompose in the body.

3. The medical valve implant according to claim 1, characterized in that one or more auxiliary devices include at least one anchoring device that is intended to remain in the body after implantation and is formed, at least in sections, of a material that can decompose in the body.

4. The medical valve implant according to claim 1, characterized in that the decomposable material includes a polymer selected from the group consisting of polydioxanone, polyglycolide, polylactic acid, poly-ε

-caprolactone, and a di- or triblock copolymer;

wherein the polylactic acid is optionally selected from the group consisting of poly-L-lactide, poly(D,L-lactide), and a copolymer or blend thereof optionally selected from the group consisting of poly(L-lactide-co-glycolide), poly(D,L-lactide-co-glycolide), poly(L-lactide-co-D,L-lactide), and poly(L-lactide-co-trimethylene carbonate);

wherein the di- or triblock copolymer comprises an above-listed lactide with polyethylene glycol, polyhydroxyvalerate, ethylvinylacetate, polyethylene oxide, polyphosphorylcholin, polyhydroxybutyric acid (optionally atactic, isotactic, syndiotactic, or a blend thereof), poly(ortho ester), or a polyanhydride.

5. The medical valve implant according to claim 1, characterized in that the decomposable material includes magnesium.

6. The medical valve implant according to claim 1, characterized in that homocysteinic acid is provided as a deposit-inhibiting or calcification inhibiting coating.

7. The medical valve implant according to claim 6, characterized in that the one or more positioning devices is provided with the deposit-inhibiting or calcification-inhibiting coating.

8. The medical valve implant according to claim 1, characterized in that the support frame includes a self-expanding stent.

9. The medical valve implant according to claim 1, characterized in that the support frame includes an elastic and/or superelastic material.

10. The medical valve implant according to claim 1, provided as an aortic valve.

11. The medical valve implant according to claim 1, provided as a pulmonary valve or mitral valve or tricuspid valve.

12. A medical valve implant for implantation in the animal body and/or human body, comprising a support frame that includes a first end and a second end, which are disposed on opposite ends of the support frame in a main extension direction of support frame, characterized in that the support frame is formed, at least in sections, of a material that can decompose in the body.
