摘要：
A prosthetic medical device is formed by the combination of a biological tissue a shape memory polymer structure. The biological tissue provides an in-situ physiological function of the device. The shape memory polymer provides a capability for minimizing the device profile during insertion and then deploying after placement into a memory shape that achieves suitable mechanical structure and stability within an anatomical lumen or cavity. This configuration may be applied to form various prosthetic devices including aortic, mitral, and tricuspid valves in the heart venous valves anti-reflux valves for the lower esophageal sphincter and other biological valve structures. Alternatively, an entirely non-biologic implementation using only shape memory polymer-based structures may be used as a prosthetic valve device.
