Abstract:

The present invention discloses a process for producing a braided suture having an improved knot strength comprising heating a braided suture coated with a low molecular weight biocompatible polymer to a temperature sufficient to melt the low molecular weight biocompatible polymer for a time sufficient to allow the low molecular polymer to be redistributed into the interstices of the braided suture thereby providing a coated braided suture with an improved knot tensile strength. Also disclosed is the coated braided suture having a low molecular weight polymer optimally dispersed throughout the braided sutures cross-section.
