Abstract
This invention relates to processes of preparing heterogeneous graft material from animal tissue. Specifically, the invention relates to the preparation of animal tissue, in which the tissue is cleaned and chemically cross-linked using both vaporized and liquid cross-linking agents, resulting in improved physical properties such as thin tissue and lowered antigenicity, thereby increasing the ease of delivering the tissue during surgery and decreasing the risk of post-surgical complication, respectively.
Claims17
A prosthetic tissue material for surgical purposes which is substantially non-antigenic, non-thrombogenic, calcification-resistant, and tear-resistant comprising a vapor-crosslinked and liquid-crosslinked collagen material comprised of 95-99% collagen that is derived from denucleated, digested, and compressed collagen-based tissue, said prosthetic tissue material having an average cross-sectional thickness ranging from 0.0508 mm to 0.508 mm.
