New biocompatible and biodegradable polymers
Introduction Porous biodegradable scaffolds are ideal materials on which, new tissue may be grown. These new tissues are used as graft material to replace damaged tissue removed during surgery. These polymers may also be used in drug delivery systems and for medical device coating. Technology description Researchers at the University of Washington have developed a new family of biodegradable, biocompatible polymers made of repeating subunits of amino acid monomer units and low molecular weight polyethylene glycol (PEG). They may be used to grow graft material to replace tissue removed during surgery, such as cancerous esophageal tissue. The polymer elicits minimal or no inflammatory response upon degradation in the human body. A variety and geometries and porosities are possible using this new family of polymers. Business opportunity Applications for this new biocompatible, biodegradable material exist in tissue engineering, drug delivery, and medical device coating. Approximately 8 million surgical procedures are performed annually in the US as a result of tissue damage from accidents and various diseases. Stage of development This technology has been reduced to practice. Intellectual property position The technology is available for licensing. The UW has US and foreign patents pending for this technology.
