Abstract
The handling characteristics, including particularly the knot run down and tissue drag characteristics, of non-absorbable surgical sutures are improved by a coating of a lubricating film of a bioabsorbable copolymer having polyoxyethylene blocks and polyoxypropylene blocks, and which bioabsobable copolymer has a molecular weight such that it is pasty to solid at 25.degree. C. This lubricant coating is absorbed in tissue in less than about 48 hours--which results in improved long term knot security.
