Resorbable and biocompatible glass fiber bundle having a well-defined diameter and process for making such

A method for obtaining a glass fiber bundle, comprising the steps of:

• a) providing a resorbable and biocompatible glass composition melt,
• b) providing the glass composition melt to a first bushing having a plurality of orifices,
• c) allowing or forcing the glass composition melt to flow through orifices of the first bushing, producing an intermediate glass melt stream,
• d) collecting the intermediate glass melt stream in a second bushing having a plurality of orifices, and allowing or forcing the intermediate glass melt stream through the orifices of the second bushing to obtain a second glass melt stream, and
• e) attenuating the second glass melt stream from the orifices of the second bushing to obtain fibers and letting the glass melt stream solidify to obtain a glass fiber bundle.
