Abstract
We have discovered a surgical filament suitable for use as a suture or ligature that comprises a multifilament core having a plurality of filaments that are oriented having an external surface and internal interstices; and an outer coating that bonded to the external surface of the core but does not penetrate into the internal interstices of the core and a process for making these sutures.

A surgical filament suitable for use as a suture or ligature that comprises a multifilament core having a plurality of filaments that are oriented having an external surface and internal interstices;
- and an outer coating that bonded to the external surface of the core but does not penetrate into the internal interstices of the core.
A process for forming a surgical filament suitable for use as a suture or ligature comprising:
- meltcoating the external surface of an oriented biocompatible multifilament core with a melted biocompatible polymer wherein the melted biocompatible polymer is cooled to form an outer coating that bonds to the external surface of the multifilament core but does not penetrate into the internal interstices of the multifilament core.
