Patent ID: 8563024

Claim:
A method of making a component, the method comprising mixing together, without melting, a bioabsorbable polymer material and a bioactive filler material in the form of dry particulate materials, wherein an amount of heat is applied during the mixing, the amount of heat being below the melting point of the bioabsorbable polymer, but sufficient for the surface of the bioabsorbable polymer to become sticky and aid cohesion; feeding the mixture dry to an injection moulding machine and injection moulding the mixture to form the component such that particles of the filler occur embedded within and exposed at the surface of the component, such that the particles extend beyond the surface of the component, the particle size of the polymer material being between 0.5 mm and 5 mm, the filler having a particle size of less than 100 μm and constituting between 1% and 50% of the mixture by weight.
