Abstract:
1. A barbed monofilament comprising a triangular primary cross-section defined by a periphery including first, second and third points of said triangle, and a plurality of barbs formed therein, wherein successive barbs are staggered around the periphery of the monofilament, and extend inwardly into the monofilament to a predetermined depth from the first, second and third points respectively, and wherein a distal portion of each barb is defined by a cut extending for a first length at a substantially constant angle relative to a longitudinal axis of the monofilament, and a proximal portion of each barb is defined by a cut extending for a second length at an angle of approximately zero degrees relative to the longitudinal axis of the monofilament, wherein the barbed monofilament is comprised of a non-absorbable material selected from the group consisting of polyolefins, polyamides and polyvinylidene fluoride, and wherein the barbed monofilament is adapted for use as an implantable surgical suture for approximating tissue.
