Abstract
The invention is a multifilament thermoplastic surgical suture having a plurality of meltfused filaments where the filaments are only melt fused for a controlled length from at least one end of the suture. This melt fused end invention eliminates the end dipping operation for multifilament sutures. Preferably, the melt fused or bonded length of suture has at least eighty percent of the tensile strength of an unfused portion, as a substitute for the end-dipped suture.
