Absorbable Sutures

Natural absorbable surgical suture made from purified connective tissue taken from sheep or bovine intestines

Chromic surgical gut sutures are natural absorbable surgical sutures made from purified connective tissue, treated with chromic salts to extend the absorption period and reduce tissue reaction. Typically used in pediatric surgery, urology, and gynecology, these sutures are absorbed by the body’s enzymes within 90 days.

RTMED, located in Shandong, China where 90% of the world’s catgut sutures are produced, operates the largest catgut production facility in Asia. Our sutures feature high gloss, consistent thickness, with a diameter variance controlled to within 1-2 threads. The longest polished suture can reach up to 6 meters, with high polishing efficiency. Our sutures exceed EU tensile strength standards by 50% and offer superior performance with minimal tissue reaction using patented coating technology.

Advantages

Its high initial tensile strength ensures reliable support throughout the healing process.
Ensures smooth suture placement and knot security through excellent handling properties
Treated with chromic salts to reduce tissue inflammation and improve healing
Absorbed consistently by the body’s enzymes within 90 days, ensuring predictable performance

Applications

Chromic catgut sutures are primarily used for general soft tissue closure and ligation, especially in general surgery, gastrointestinal surgery, urology, pediatric surgery, gynecology, and ophthalmology. These sutures are medical-grade absorbable sutures, connected to a high-quality stainless steel needle that meets regulatory standards, offering excellent elasticity and toughness. The sutures are absorbed by enzymes within 90 days, ensuring reliable performance during the healing process.
