Abstract: Improved prosthetic valves, their methods of manufacture, and systems and devices for manufacturing the valves are described. The prosthetic valves can be configured for transcatheter implantation. The prosthetic valves can have artificial leaflets. The prosthetic valves can be manufactured in numerous ways, such as by polymeric dipping processes and/or electrospinning. Sponge-like polymers for valves and other medical devices are also disclosed.

Abstract: The present disclosure provides soft block copolymer segments of Formula 1 for thermoplastic polyurethane or polyurethaneurea elastomer materials and their reaction products with divalent compounds, such as diisocyanates, chain extenders and optional additional polyols or polyamines. Also disclosed herein are methods for the production of the soft block copolymer segments, and possible applications of these materials in the formation of biomaterials for articles including medical devices such as implants, heart valves and drug delivery devices.

Abstract: A prosthetic valve has a support structure that meets with a plurality of leaflets capable of transitioning between open and closed states. The support structure can include a base frame with a polymer coating and the leaflets can be artificial. The interface between the support structure and each leaflet can be at least partially convex when viewed from an exterior of the support structure along a normal to a plane formed by a central axis of the support structure and a central axis of the leaflet.

Abstract: Prosthetic heart valves having elastic leaflets and an elastic support structure are described. The support structure can store a load transferred from the leaflets as potential energy and then release it in the form of kinetic energy to exhibit a precursory transition from the closed position to the open position. The support structures can exhibit a sinusoidal movement profile at a base edge during the precursory transition.
