Abstract: A prosthetic heart valve leaflet includes a plurality of electrospun fibers at least partially embedded in a polymer matrix. The plurality of fibers includes a first polyisobutylene urethane copolymer having a first predetermined weight average percentage of hard segment portions and the polymer matrix includes a second polyisobutylene urethane copolymer having a second predetermined weight average percentage of the hard segment portions, wherein the first predetermined weight average percentage of the hard segment portions is greater than the second predetermined weight average percentage of the hard segment portions.
