Abstract:
A prosthetic valve comprising a conical shaped sheet member comprising poly(urethane urea), the sheet member having a plurality of interstices that are disposed uniformly on the sheet member wall and configured to transition from an open position when the sheet member is in an expanded position, where fluid flow is allowed to be transmitted through the sheet member, to a closed position when the sheet member is in a collapsed position, where the interstices restrict fluid flow through the sheet member.

Claim (Index 2):
A prosthetic valve for modulating fluid flow through a cardiovascular structure during cardiac cycles of a heart, said fluid flow exhibiting a plurality of positive and negative flow pressures during said cardiac cycles, said prosthetic valve comprising:\n a conical shaped sheet member, said sheet member comprising an extracellular matrix (ECM) composition, said ECM composition comprising acellular ECM from a mammalian tissue source and poly(urethane urea), said sheet member further comprising an open proximal annulus engagement end configured to engage said cardiovascular structure and receive said fluid flow therein, a distal end, and inner and outer surfaces, said distal end being configured to restrict said fluid flow therethrough, said sheet member further comprising a plurality of linear interstices that extend through said sheet member inner and outer surfaces, said outer surface defining an outer surface region, said plurality of linear interstices being uniformly spaced on said outer surface region, said sheet member being configured to transition from an expanded position when said proximal annulus engagement end of said sheet member is engaged to said cardiovascular structure and receives said fluid flow therein, and said fluid flow exhibits a first positive flow pressure of said plurality of positive flow pressures, to a collapsed position when said fluid flow exhibits a first negative flow pressure of said plurality of negative flow pressures, said plurality of interstices being configured to transition from an open position when said sheet member is in said expanded position, whereby said plurality of interstices allow said fluid flow to be transmitted through said sheet member, to a closed position when said sheet member is in said collapsed position, whereby said plurality of interstices restrict said fluid flow through said sheet member, said sheet member being further configured to remodel, and 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 proximal annulus engagement end of said sheet member is engaged to said cardiovascular structure, wherein said proximal annulus engagement end of said sheet member is disposed proximate damaged tissue of said cardiovascular structure.
