Chromic gut sutures are absorbable sterile surgical sutures composed of purified connective tissue derived from the serosal layer of beef intestines. they are packaged in a solution of 89 percent isopropanol 10 percent water and 1 percent triethanolmaine. chromic gut is treated with chromic salt solution. mild chromic sutures are specially treated for ophthalmic and cuticular applications. 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; uniform treatment with a buffered chromium salt solution resulting in a chromic strand with a more predictable strength and uniform in-vivo absorption.
