Abstract:
A dyed braided suture is formed by dry blending a colorant and a thermoplastic resin; extruding the blend by melt spinning to form filaments; drawing the filaments, braiding the drawn filaments and converting the braided filaments to a suture.

Abstract:
A braided polyester suture made from polyester yarn filaments having a tenacity of from about 7 to about 11 g/denier, a percent elongation to break of less than about 30 percent and the polymer from which the filaments are made has an intrinsic viscosity greater than about 0. 95. The invention also provides an implantable medical device constructed from yarn filaments having these properties.
Method Of Forming An Absorbable Biocompatible Suture Yarn
A process for producing an absorbable biocompatible medical suture yarn includes the step of spin drawing a bioabsorbable polymer to form suture filaments. A spin finish using a non-aqueous based carrier is applied to the filaments during processing, and an air entangling step is used after the filaments are combined to form the suture yarn.
