First Claim
Patent Images
1. A prosthetic valve comprising:
- a frame; and
a leaflet coupled to the frame and movable between open and closed positions, the leaflet including at least one coherent single layer and an elastomer, the coherent single layer having pores and is a synthetic polymer, the elastomer present in the pores such that the coherent single layer is impermeable.

Abstract
Thin, biocompatible, high-strength, composite materials are disclosed that are suitable for use in a prosthetic valve for regulating blood flow direction. In one aspect, the leaflet material maintains flexibility in high-cycle flexural applications, making it particularly applicable to high-flex implants such as a prosthetic heart valve leaflet. The leaflet material includes a coherent single layer and an elastomer, wherein the elastomer is present in the pores of the porous coherent single layer.
