Abstract
A contoured biological tissue for a bioprostheses, such as a cardiac/vascular patch or a bioprosthetic heart valve, and methods of contouring the tissue, are described. A predetermined pattern is provided on the tissue, comprising a plurality of ridges or depressions that are configured to facilitate cellular migration in a first direction and discourage cellular migration in a second direction. The biological tissue can be used in connection with a bioprosthetic heart valve comprising a biological tissue leaflet structure coupled to a supporting frame.
