Biocompatible and resorbable melt derived glass compositions which include: SiO60-70 weight-%, NaO 5-20 weight-%, CaO 5-25 weight-%, MgO 0-10 weight-%, PO0.5-3.0 weight-%, BO0-15 weight-%, AlO0-5 weight-%, and which contain less than 0.05 weight-% potassium. Biocompatible and resorbable glass fibers manufactured from these glass compositions, medical devices containing fibers of the invention, the use of these compositions for the manufacture of glass fiber and the use of the fibers for the manufacture of medical devices are also disclosed.

Resorbable and biocompatible fibre glass compositions and their uses

A composite material including biocompatible and bioresorbable glass, a biocompatible and bioresorbable matrix polymer and a coupling agent capable of forming covalent bonds. The composite also includes a compatibilizer, where at least 10% of the structural units of the compatibilizer are identical to the structural units of the matrix polymer, and the molecular weight of the compatibilizer is less than 30000 g/mol. The use of this composite, a medical device which includes the composite and a method for preparing the composite are also disclosed.

Biocompatible composite and its use

The present invention relates to an implantable paste comprising bioactive glass spheres having a size distribution of 50-425 &#x3bc;m, low molecular weight polyethylene glycol having a molecular weight range of 200-700 g/mol, medium molecular weight polyethylene glycol having a molecular weight range of 700-2500 g/mol and high molecular weight polyethylene glycol having a molecular weight range of 2500-8000 g/mol, 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.
