Patent ID: 8163030

Claim:
A moldable implant mass composition for use in repairing a bone defect in a living organism, comprising: a plurality of biocompatible synthetic non-polymeric granules, said granules having an equivalent diameter of about 100 μm to about 4,000 μm; a biocompatible polymer coating at least a portion of the implant mass, the implant mass comprising a composite matrix of the granules bound to each other by adhesion between the biocompatible polymer disposed on adjacent granules, and macropores between adjacent granules, so as to form an implant mass comprising a plurality of distinct granules coated with said biocompatible polymer, said biocompatible polymer comprising about 4% to about 20% of the total weight of the implant mass; and a plasticizer in said implant mass in an amount sufficient to condition at least a portion of said biocompatible polymer so that said implant mass is plastically deformable into a desired shape and then hardenable upon removal of at least a portion of said plasticizer from said implant mass, and so that adhesion between the biocompatible polymer coating disposed on adjacent granules is promoted.
