Patent ID: 8858976

Claim:
An implantable paste comprising a) bioactive glass spheres having a size distribution of 50-425 μm, b) low molecular weight polyethylene glycol having a molecular weight range of 200-700 g/mol, in an amount of 2-15 wt-% of the total weigh of the paste, c) medium molecular weight polyethylene glycol having a molecular weight range of 700-2500 g/mol, in an amount of 8-48% of the total weight of the paste, and d) high molecular weight polyethylene glycol having a molecular weight range of 2500-8000 g/mol, in an amount of up to 10 wt-% of the total weight of the paste, with the proviso that the molecular weight of the low molecular weight polyethylene glycol and of the medium molecular weight polyethylene glycol differ from each other by at least 80 g/mol and that the molecular weight of the medium molecular weight polyethylene glycol and of the high molecular weight polyethylene glycol differ from each other by at least 300 g/mol.
