Patent Images
1. A prosthetic heart valve comprising:
- a base;
a plurality of polymeric leaflets, each leaflet having a root portion coupled to the base, each leaflet having an edge portion substantially opposite the root portion and movable relative to the root portion to coapt with a respective edge portion of at least one of the other leaflets of the plurality of leaflets, each leaflet comprising) at least two polymers, and each leaflet having a composition gradient of each of the at least two polymers along at least one portion of the leaflet.

Abstract
A prosthetic heart valve includes a base and a plurality of polymeric leaflets. Each leaflet has a root portion coupled to the base, and each leaflet has an edge portion substantially opposite the root portion and movable relative to the root portion to coapt with a respective edge portion of at least one of the other leaflets of the plurality of leaflets. Each leaflet includes) at least two polymers along at least one portion of the leaflet, and each leaflet has a composition gradient of each of the at least two polymers along at least one portion of the leaflet.

20. A method of forming a prosthetic heart valve, the method comprising:
-
forming a base defining a substantially cylindrical passage therethrough; forming a plurality of leaflets, each leaflet having a root portion and an edge portion substantially opposite the root portion, each leaflet comprising at least two polymers, and each leaflet having a composition gradient of each of the at least two polymers along at least one portion of the leaflet; and coupling the root portion of each of the plurality of leaflets to the base such that each respective edge portion is substantially opposite the root portion and movable relative to the root portion to coapt with a respective edge portion of at least one of the other leaflets of the plurality of leaflets.
