Abstract

A mechanical transcatheter heart valve prosthesis including a support structure that can be expanded from a first size designed for minimally invasive insertion to a functional second size and a flexible heart valve made of a composite material containing woven fabric that is embedded in an elastic matrix and locally reinforced by fibers, the heart valve comprising a plurality of leaflets.

Claims

1. A mechanical transcatheter heart valve prosthesis, comprising:

a support structure, which expands from a first size designed for minimally invasive introduction to a functional second size; and

a flexible heart valve comprising a composite material containing woven fabric that is embedded in an elastic matrix and locally reinforced by fibers, the heart valve comprising a plurality of leaflets.

2. The heart valve prosthesis according to claim 1, wherein the heart valve is reinforced by the fibers in an edge section adjoining the support structure.

3. The heart valve prosthesis according to claim 1, wherein the heart valve has a tricuspid contour.

4. The heart valve prosthesis according to claim 1, wherein the matrix comprises polyurethane.

5. The heart valve prosthesis according to claim 1, wherein the fibers comprise high-strength polyethylene (PE).
