Patent ID: 8580865

Claim:
A plastically deformable preparation for bone repair or replacement, comprising a porous particle component that is not easily soluble in water suspended in a paste-like mixture comprising water or alcohol as a solvent and at least one component that is soluble in water or alcohol, the porous particle component that is not easily soluble in water comprising 60-98% by weight and the paste-like mixture comprising 1-30% by weight of the preparation, the particles of the porous particle component having a diameter in a size range that is essentially greater than a phagocytable particle and smaller than the passage diameter of standard injection cannulas and the soluble component comprising 0.1-3% by weight of the preparation, the porous particle component including particle sizes in the range of 0.1 to 50 μm, wherein the component that is soluble in water or alcohol is hyaluronic acid having a molecular weight of 1,500,000 to 4,500,000 Daltons before sterilization of the preparation, and wherein the preparation is sterilizable with dry heat or with gamma rays at a dosage of 8 to 30 kGy.
