CONTROLLED DRUG DELIVERY DEVICE COMPRISED OF A BLEND OF POLYMERS

摘要

Biodegradation of a drug delivery system or temporary internal suture or device is controlled by preparing a blend of biodegradable polymers having distinct biodegradation rates. The resulting article has a unique biodegradation rate distinct from that of the component polymers. Predetermined or preselected biodegradation rates can be achieved by selection of appropriate blend components.
