Abstract

Surgical sutures having desired flexibility and strength are made from at least 19 stainless steel filaments, each having a diameter not greater than 0.0018 inch. Small gauge sutures may be made, for instance, from nineteen filaments each of 0.0012 inch diameter, this being given a twist of twelve turns per inch, but larger diameter sutures are preferably made by twisting a number of filaments together to form a strand and then twisting several strands together to make the finished suture, the twist of the strands being opposite to that of the filaments. Such a wire is cleaned anodically and may then be encased in polytetrafluorethylene, which may be done by wrapping a strip of a film of this material around it and then passing it through a heating device to fuse it into a unitary whole. The suture may be cut by means of the closely spaced electrodes while a current is passed between them. This cuts the wire by melting it and results in fusing of the ends so that untwisting is prevented. It also leaves an end which may be conveniently inserted into the end of a surgical needle, where it is secured by crimping.ALSO:Surgical sutures made from stainless steel wire are given the desired flexibility by being made from at least 19 stainless steel filaments, each having a diameter not greater than 0.0018 inch.

Such a suture is cleaned anodically and may then be encased in polytetrafluorethylene, which is preferably done by wrapping a strip of a film of this material around it and then passing it through a heating device to fuse it into a unitary whole. The suture may be cut by means of two closely spaced electrodes pressed against it while a current is passed between them. This cuts the wire by melting it and results in fusing of the ends, so that untwisting is prevented.
