1. A prosthetic valve, comprising:
- a conical shaped sheet member comprising an extracellular matrix (ECM) composition, said ECM composition comprising acellular ECM from a mammalian tissue source,said sheet member further comprising a longitudinal axis, proximal and distal ends, and an inner surface defining an interior cavity,said sheet member further comprising a plurality of open slit regions that are disposed uniformly on linear planes that are parallel to said sheet member longitudinal axis,said sheet member further comprising a proximal annulus engagement end diameter and length ratio in the range of 5;
1 to 2;
1,said sheet member being configured to induce host cell and tissue proliferation, remodeling of damaged cardiovascular tissue and regeneration of new cardiovascular tissue and tissue structures with site-specific structural and functional properties, when said sheet member is disposed proximate a valve annulus; and
a multi-link support stent structure disposed in said sheet member interior cavity.
