ABSTRACT:
Novel implantable tissue fixation methods and compositions are disclosed. Methods and compositions of tissue, fixed using polymeric and/or variable length crosslinks, and di- or polymercapto compounds are described. Also described are the methods and compositions wherein the tissue is fixed using biodegradable crosslinkers. Methods and compositions for making radio-opaque tissue are also described. Methods and compositions to obtain a degradable implantable tissue-synthetic biodegradable polymer composite are also described. Compositions and methods of incorporating substantially water-insoluble bioactive compounds in the implantable tissue are also disclosed. The use of membrane-like implantable tissue to make an implantable drug delivery patch are also disclosed. Also described are the compositions and methods to obtain a coated implantable tissue. Medical applications implantable tissue such as heart valve bioprosthesis, vascular grafts, meniscus implant, drug delivery patch are also disclosed.
