ABSTRACT:
A concentric mating stent tissue heart valve which is capable of being assembled with a variety of tissue sources is provided. The valve comprises at least one piece of tissue clamped between an inner and an outer stent. The outer stent is configured with a plurality of spaced posts extending from a base, wherein the posts are configured with open windows so that at least a portion of the tissue in the assembled valve is exposed through the windows. Several embodiments of the outer stent are disclosed, including where the outer stent comprises a crimped metal wire frame covered with a Dacron tube.
