A prosthesis for replacing or strengthening a particular part of the body is coated with a biodegradable, resorbable and biocompatible surface coating. Biologically active microspheres which controllably release the biologically active agents are embedded in the surface coating. The biologically active microspheres include encapsulated PGE1 in a polyethylene glycol mix, which over a period of time dissolves and releases the PGE1 into the body part.
