Abstract:
Methods of making biodegradable polymeric devices, such as stents, with one or more modifications to alter the degradation rate, and the biodegradable polymeric devices are described. Modifications include blending of two polymers, one with a different degradation rate, inclusion of additives to alter the degradation rate, and the use of polymers of a high polydispersity.
