摘要:
Anchored cardiovascular valves (40) having a support member (10) of remodelable decellularized ECM material with at least one leaflet (30) formed therein that is sized and configured to selectively restrict regurgitating blood through the valve (11, 40, 50, 60, 70), and at least one anchoring mechanism (20A, 20B, 42A, 42B, 52A, 52B, 62A, 62, 65, 67). In a preferred embodiment of the invention, the anchored valves (50) have two anchoring mechanisms (20A, 42A, 52A, 62A), i.e. proximal and distal anchoring mechanisms (20A, 42A, 52A, 62A).

摘要:
Vascular grafts for treating, reconstructing and replacing damaged or diseased cardiovascular vessels that are formed from decellularized extracellular matrix (ECM). The vascular grafts include outer or outer and inner coatings that provide structural reinforcement.
摘要:
A valve mounting apparatus having an elongated tubular mesh structure with proximal and distal ends, a cardiovascular structure engagement region disposed between the proximal and distal ends, and a lumen therethrough, the distal end of the structure including a valve engagement region that is configured to engage a first end of a prosthetic valve, the mesh structure being configured to transition from a pre-deployment configuration, wherein the structure is capable of being disposed at a cardiovascular valve region, such as a valve annulus region, to a post-deployment expanded configuration, wherein the cardiovascular structure engagement region is anchored to the cardiovascular valve region.
摘要:
A prosthetic atrioventricular tissue valve comprising a continuous tubular member formed from a first biocompatible material, the tubular member having proximal and distal ends, and at least one valve leaflet fomied therein, the distal end of the tubular member including cardiovascular structure engagement means for connecting the tubular member to a cardiovascular structure, the cardiovascular structure engagement means comprising a plurality of elongated members that extend distally from the distal end of the tubular member.
