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.

Prosthetic heart valves having fiber reinforced leaflets

A tubular stent includes a stent body having a distal end and a proximal end, a covering surrounding at least a portion of the stent body and an adjustable annular ring secured to the stent body. The adjustable annular ring is configured to permit radial expansion of the adjustable annular ring while resisting radial compression of the adjustable annular ring.

Stent with anti-migration feature

A prosthetic heart valve includes a base and one or more heart valve leaflets. At least a portion of the leaflet including a composite material that contains a polymer substrate and a pre-stressed reinforcement element at least partially disposed in the polymer substrate.

Prosthetic heart valves including pre-stressed fibers

Disclosed is a braiding disk handle for holding a kumihimo braiding disk. The braiding disk handle includes a tubular grip having a proximal end, a distal end, and a chamber extending between and through the proximal and distal ends. The grip is configured and adapted to receive a length of yarn through the extent of the chamber. The handle further includes a hollow shank attached to the distal end of the grip such that the chamber of the grip is in communication with the hollow of the shank. The shank is configured and adapted to cooperatively and detachably mate with an opening of a braiding disk. The handle further includes a shoulder formed at the distal end of the grip adjacent and perpendicular to the shank. The shoulder is configured and adapted to support at least a portion of the braiding disk while the shank is mated with braiding disk.
