ABSTRACT:
The present invention provides methods for preparing tissue for incorporation into xenografts and bioprosthetic devices. The methods of the invention make use of supercritical fluids to remove infectious materials and chemical agents from tissues, as well as to permeate a tissue with a chemical agent (e.g. tanning, cross-linking, and bioactive agents).
