Bioprosthetic tissue for use as a prosthetic valve leaflet and method of preparing
First Claim
Patent Images
1. A method of preparing a sheet of bioprosthetic tissue for use as a prosthetic valve leaflet, comprising:
- positioning a sheet of bioprosthetic tissue across an engagement face of a first patterned substrate, the engagement face defining a pattern having at least one raised region and areas of relief adjacent the at least one raised region, wherein the areas of relief define openings extending from the engagement face to a face opposite the engagement face; and
compressing the tissue against the engagement face to deform the tissue to a deformed state corresponding with the pattern.

Abstract
Methods of preparing a sheet of bioprosthetic tissue for use as a prosthetic valve leaflet are disclosed. A method includes positioning a sheet of bioprosthetic tissue across an engagement face of a first patterned substrate. The engagement face defines a pattern having at least one raised region and areas of relief adjacent the at least one raised region. The tissue is compressed against the engagement face to deform the tissue to a deformed state corresponding with the pattern.

11. A method of preparing a sheet of bioprosthetic tissue, comprising:
-
extending a sheet of tissue across a patterned surface of a first substrate; removably securing the sheet of tissue to the patterned surface; applying a force to press the tissue against the patterned surface to compress the tissue and reduce tissue thickness in select areas corresponding to the patterned surface; and treating the tissue with a fixative, wherein the application of force is facilitated by a vacuum source. - View Dependent Claims (12, 13, 14, 15)
