Patent ID: 8658217

Claim:
A method for preparing an implantable osteogenic medical material, comprising: providing a dried, porous material defining one or more reservoirs formed therein, the dried, porous material including a particulate mineral material having an average particle diameter of about 0.4 mm to about 5 mm embedded within a disruptable collagenous matrix, said dried, porous material comprised 70% to 90% by weight of the particulate mineral material and 10% to 30% by weight of collagen, the collagen matrix including insoluble collagen fibers and soluble collagen present in a weight ratio of 4:1 to 1:1; and applying an aqueous medium to the one or more reservoirs of the dried, porous material and disrupting the collagen matrix so as to prepare a malleable, cohesive, shape-retaining putty that comprises 60% to 75% by weight of the aqueous medium.
