Patent ID: 6933328

Claim:
A composition suitable for preparing a biodegradable implant, comprising a crosslinkable multifunctional prepolymer, the number average molecular weight of the said crosslinkable multifunctional prepolymer being in the range of 150 to 20,000 whereby the said composition has a viscosity such that it is deformable at a temperature of 0° to 6° C. into a three-dimensional shape, the said crosslinkable muitifunctional prepolymer being crosslinkable within the said temperature range and comprising at least one biodegradable region selected from the group consisting of poly-α-hydroxyacids, polyesters, polyaminoacids, polyorthoesters and mixtures thereof, or polyacetals, and at least one polymerizable region having at least two polymerizable end groups, wherein the said composition further comprises a biocompatible unsaturated functional monomer end an effective amount of a mineral biologically-active component delivery system and/or an effective amount of a biocompatible degradable or water-soluble porosity-inducing component or porous polymethacrylate spheres.
