  • Braided polyester suture and implantable medical device
    Patent number: 6203564
    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
    Patent number: 5688451
    Abstract: 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.
