Chromic Gut (OEM)

CHROMIC GUT   Twisted Gut Natural Absorbable Suture


Chromic Gut sutures are absorbable sterile surgical sutures composed of purified connective tissue (mostly collagen) derived from the serosal layer of beef (bovine) or the submucosal fibrous layer of sheep (ovine) intestines.  They are packaged in a solution of 90% isopropanol, 0.5% sodium benzoate, 0.5% diethylethanolamine, and water q.s. ad 100%.  Chromic Gut is treated with a chromic salt solution.


The manufacturing of catgut raw material, consisting of long ribbons of highly selected serosal tissue, ensures:

•   Purity of collagen for optimal tensile strength and in vivo performance.

•   Uniform treatment with a buffered chromium salt solution.

•   Surface smoothness to facilitate knot run-down and knot strength.


Many factors may affect the rate of tensile strength loss.  These include:

•  Type of suture

•   Presence of infection

•   Tissue sites


Absorption of Chromic Gut sutures occurs by an enzymatic process similar to the digestion of an animal protein by the body.  Being enzymatic, the process is subject to different influencing factors (see above) and it is virtually impossible to indicate the exact designation of a consistent absorption time.




Chromic Gut is available in various USP sizes.  Chromic Gut is supplied affixed to various needle types in one (1) dozen boxes, or in veterinary suture cassettes.
