Abstract
A prosthetic heart valve includes a support structure and a valve assembly disposed within the support structure, the valve assembly including a plurality of leaflets.

A prosthetic heart valve, comprising:
- a support structure;
- and
- a valve assembly disposed within the support structure, the valve assembly including a plurality of leaflets,
- wherein each leaflet is formed from a composite material, the composite material including a metal substrate in the form of a mesh having a plurality of openings, and a polymer coated on the metal substrate, the mesh being formed of a first flat mesh of biocompatible metal wire layered on a second flat mesh of biocompatible metal wire without a layer of the polymer between the first flat mesh and the second flat mesh.
