Definition: Bioresorbable polymers are inherently biocompatible, yet hydrolytically unstable. This allows for applications in temporary implants that are intended to be absorbed and metabolized by the body. A range of physical and degradation properties allows these polymers to be used for applications that include orthopedic fixation, vascular stents, tissue engineering and controlled drug delivery. Common bioresorbable polymers include PLA, PGA, PLGA and PCL.
Purpose:Â Provide an overview of bioresorbable polymers, properties and applications.
