Plain Catgut Suture

Natural Absorbable Suture U.S.P. (Sterilized Surgical Needle Suture)

Plain Catgut Suture is a fast-absorbing monofilament natural surgical gut suture made by twisting together strands of collagenous material taken from the submucosal layers of the small intestine of healthy sheep and goats.

Fast-absorbing surgical gut sutures are sterile and elicit only a minimal tissue reaction during absorption. In-house needle manufacturing provides better needles with optimum sharpness, which finally delivers smooth riding on tissue during suturing.


A plain catgut suture is a naturally absorbable surgical suture. Catgut absorbs by simple enzymatic mechanisms, and absorption is not as predictable as in synthetic sutures. Catgut sutures tend to absorb faster in infected tissues. Catgut suture initial tensile strength is lost within 7 to 10 days and is absorbed completely in 60 to 70 days. It is non-adhering and biologically inert.

  • Best use for: general closure, obstetrics, gynecology, and gastro-intestinal tract surgery.
  • Ultimate Suture: Fast Healing Tissue and Muscles, Soft Tissue Approximation.
  • Plain Catgut Suture meets all the requirements established by the United States Pharmacopoeia for natural absorbable surgical sutures.
Can also be supplied in different needle length and suture size combination depending on the requirement.
