Available as a straw coloured suture. Surgical gut is made from the intestinal submucosa tissue of sheep. These casings are split into ribbons, which are cleaned chemically as well as mechanically and matched by computers to meet the most exacting demands for diameter and tensile strength. Then an exclusive electronic spinning process creates a strand that is virtually a monofilament for dependable strength and holding power. Finally the strand is polished to size to an accuracy of five thousand of a millimeter to produce an extremely smooth, highly uniform suture. Surgical Gut draws through delicate tissue without sawing, ties down securely and holds uniformly and predictably, until the wound regains tensile strength.
