ABSTRACT:
Disclosed is a biodegradable polylactic acid polymer delivery system for delivery of bone morphogenic protein (BMP) to induce formation of new bone in viable tissue. The delivery composition is substantially pure BMP in combination with a biodegradable polylactic acid polymer and it is prepared by admixing the BMP with the biodegradable polymer. The composition is implanted in viable tissue where the BMP is slowly released and induces formation of new bone.
