Patent ID: 8734835

Claim:
An implantable osteogenic medical implant, comprising: a malleable, cohesive, shape-retaining putty comprising 60% to 75% by weight of an aqueous liquid medium and including a bone morphogenic protein incorporated at a level of about 0.6 mg/cc to about 2 mg/cc of the putty; said putty including mineral particles dispersed therein having an average particle diameter in the range of 0.4 mm to 5 mm at a level of 0.25 g/cc to 0.35 g/cc in the putty, the mineral particles comprising a synthetic ceramic; said putty further including insoluble collagen fibers at a level of 0.04 g/cc to 0.1 g/cc of the putty, wherein the mineral particles form a scaffold for bone ingrowth and comprise biphasic calcium phosphate that has a tricalcium phosphate: hydroxyapatite weight ratio of 50:50 to 95:5 and a weight ratio of insoluble collagen fibers to soluble collagen in the material is at a range of 4:1 to 1:1.
