Abstract: A delivery device is described for use in a TAVR procedure for replacement of a diseased cardiac valve with a prosthetic valve using a minimally invasive procedure. The invention includes structural features of a prosthetic valve that are mated to corresponding structural features on a catheter-based delivery system. Individual structures and operations of the delivery system are specially designed for the TAVR procedure and operate to improve the delivery and placement of the prosthetic valve at the native annulus such that the surgeon can orient and release the prosthetic valve in a controlled manner to improve the placement and deployment of the prosthetic valve.

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: 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: 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.
