摘要
This invention relates to tanning biomaterial to obtain calcification resistant biomaterial with good mechanical properties for bioprosthetic applications. The biomaterial of the invention is obtained by tanning tissue by any method except by oxidation, and then at a later time tanning the tissue by any of the oxidative fixation methods. The process was shown to provide beneficial results with the most frequently used fixation process, which involves fixating tissue with glutaraldehyde. Tissue fixated with glutaraldehyde and then by oxidative fixation has a lower calcification potential than does glutaraldehyde- only tanned tissue and has mechanical properties more similar to glutaraldehyde tanned tissue than to oxidative stabilized tissue. In particular, a process is described where tissue is fixed with glutaraldehyde followed by photoxidation.
