Patent ID: 8840913

Claim:
An implantable medical material, comprising: a malleable, cohesive, shape-retaining putty comprising about 40% to about 75% by weight of water; polyethylene glycol; said putty including mineral particles dispersed therein at a level of about 0.25 g/cc to about 0.55 g/cc, the mineral particles comprising biphasic calcium phosphate having a weight ratio of tricalcium phosphate:hydroxyapatite of about 70:30 to about 95:5; said putty including insoluble collagen particles at a level of about 0.04 g/cc to about 0.15 g/cc, and soluble collagen particles, wherein the insoluble collagen particles to soluble collagen particles are at a weight ratio of 75:25 to about 65:35; and said putty including a polysaccharide component at a level of about 0.01 g/cc to about 0.2 g/cc, and said polysaccharide component comprising dextran and one or more ionic polysaccharide compounds, wherein the ionic polysaccharide compounds form anionically-cross-linked gel with one or more divalent or trivalent cations.
