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: 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.
