MEMPHIS, Tenn.--(BUSINESS WIRE)--Medtronic, Inc. (NYSE:MDT) today introduced two new synthetic bone graft products developed to provide surgeons with a comprehensive MASTERGRAFT® ceramic option. MASTERGRAFT® MATRIX and MASTERGRAFT® PUTTY are designed to fill gaps in the skeletal system that are not intrinsic to the stability of the bony structure. These new grafts give surgeons more handling options, while providing an osteoconductive implant that localizes biologic components-possibly aiding cellular proliferation and osteointegration during the bone healing process.
