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.
