Plain 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%.
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
• 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 Plain 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.
Plain Gut Sutures are supplied in one dozen boxes.
