Catgut is a resorbable natural suture material that is made from collagen derived from the submucosal layer of the small intestine of sheep or the serous layer of the small intestine of cattle.

Mechanism of resorption: enzymatic biodegradation.

Time of resolution: loss of tensile strength up to 50% -7-12 days, complete resorption after 60-90 days.

Produced by various manufacturers.

Application

• As absorbable ligatures
• Wound seams in fast-healing tissues (muscles, fascia, mucous membranes, gastrointestinal tract, parenchymal organs)

Characteristics

• Reliable fixation of the node
• High strength and elasticity
• It is a natural fiber, therefore there is a possibility of an acute inflammatory transitory tissue reaction, as a response to the presence of a foreign substance.
• To increase the biological tensile strength up to 20 days, the catgut is treated with trivalent chromium salts and pyrogallol oxide (chrome-plated catgut).
