Claims
- 1. A process for coating the pores in a porous calcium phosphate mineral material with collagen, which process comprises pumping a collagen dispersion through the mineral material, which material has been placed in a mold, said mold having an inlet port and an outlet port, said ports being capable of permitting the flow of collagen dispersion but preventing the flow of said mineral material,
- wherein said pumping is conducted by pumping said dispersion into the inlet port through said porous material and out the outlet port.
- 2. The process of claim 1 wherein the mineral material is a solid porous block.
- 3. The process of claim 1 wherein the mineral material is a powder.
- 4. The process of claim 1 wherein the collagen dispersion is a dispersion containing 35 mg/ml-65 mg/ml reconstituted fibrillar atelopeptide collagen in saline.
