Plain gut sutures are absorbable sterile surgical sutures composed of purified connective tissue (mostly collagen) derived from the serosal layer of beef (bovine) intestines. the manufacture 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; suture smoothness to facilitate knot run-down and knot strength due to electronic polishing of each strand. plain gut sutures are indicated for use in general soft tissue approximation and/or ligation including use in ophthalmic surgery but not in cardiovascular or neurological surgery.
