Yang is an accomplished inventor based in Irvine, California, known for his significant contributions to the field of medical devices, particularly in the development of prosthetic heart valve technology. With a record of two patents, Yang has made remarkable strides in improving the functionality and reliability of heart valves used in medical procedures.
Latest Patents
Yang's latest innovations include two notable patents. The first patent, titled "Alternate Stent Covering for Tissue Valves," describes a prosthetic heart valve that comprises a stent with an annular base and multiple legs extending upwards. The design features a valve element that circumscribes the stent, with cooperating valve leaflets that match the number of legs. A layer of biologically-compatible material is secured to the stent, ensuring a smooth, non-abrasive outer surface that enhances the valve’s performance and minimizes wear during its operation.
The second patent, "Tubular Prostheses Prepared from Pericardial Tissue," showcases novel tubular prostheses, such as vascular or ureteral prostheses, crafted by sewing together the edges of pericardial tissue sheets. This innovative approach allows for the creation of a sturdy tubular structure that can be cut transversely without unraveling, preserving the integrity of the prosthesis. The preferred use of bovine pericardial tissue in this design offers compliance comparable to that of human arteries and veins, making it an ideal choice for medical applications.
