1. A prosthetic heart valve comprising:
- a plurality of leaflets comprising;
a composite material comprising a first plurality of polymeric fibers embedded in a polymer matrix, each fiber of the first plurality of polymeric fibers having a first common extending direction and a plurality of regularly spaced repeating undulations, wherein the plurality of regularly spaced repeating undulations of the first plurality of polymeric fibers is adapted to provide the composite material with multi-stage elastic properties; and
wherein the plurality of regularly spaced repeating undulations of the first plurality of polymeric fibers has crests that extend in a direction orthogonal to the first common extending direction;
wherein each leaflet comprises a first sleeve portion, a second sleeve portion, and a body portion disposed between the first and the second sleeve portions; and
wherein at least a portion of the first plurality of polymeric fibers extend along a linear path along the first common extending direction comprising a circumferential direction between the first sleeve portion and the second sleeve portion.
