Background on Permacol(R)Permacol(R) was developed at Dundee University over a 20 year time period andhas been patented worldwide. The key to the Permacol(R) concept lies in itscollagen Technology which uses non-reconstituted porcine dermal collagen, verysimilar in structure to human tissue. Non-collagenous material, except elastin,is removed by the TSL manufacturing process. The remaining collagen, whichretains its original 3-D structural architecture, is stabilised by a patentedcross-linking process. The result is a non-reconstituted, non-allergenic,collagen implant which is resistant to biodegradation attack, is recognised andaccepted by the body, and is able to provide a long-term support for thein-growth of new tissue and its associated blood supply.
