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.
Claims6
