Surgical Gut suture is an absorbable sterile surgical suture composed of purified connective tissue (mostly collagen) derived from the serosal layer of beef (bovine) intestines. Surgical gut suture meets all requirements established by the United States Pharmacopeia (U.S.P.) for absorbable surgical sutures. Surgical gut (Plain and Chromic) is indicated for use in general, soft tissue approximation and/or ligation, including use in ophthalmic procedures.

Absorption is complete within 70 days. Plain Catgut is ideal for tissues that heal rapidly and require minimal support.

ACTIONS:

When Surgical Gut Suture is placed in tissue, a moderate tissue inflammation occurs characteristic of foreign body response to a substance. This is followed by a loss of tensile strength and suture mass, as the proteolytic enzymatic digestive process dissolves the surgical gut. This process continues until the suture is completely absorbed. Many variable factors may affect the rate of absorption. Some of the major factors which can affect tensile strength loss and absorption rates are:

1. PLAIN gut generally absorbs more rapidly than CHROMIC gut. Plain gut is 100 percent absorbed in 30 to 60 days.

2. Infection – Surgical gut is absorbed more rapidly in infected tissue than in non-infected tissue.

3. Tissue Sites -- Surgical gut will absorb more rapidly in tissue where increased levels of proteolytic enzymes are present, as in the secretions exhibited in stomach, cervix and vagina.

DemeTech's Plain Catgut suture is an absorbable, sterile, surgical suture composed of highly purifiedconnective tissue (mostly collagen) derived from either beef or sheep intestines.

DemeTech's Plain Catgut Sutures are available in Beige. Due to an extremely short absorption period, DemeTech's Plain Catgut elicits only minimal reaction in tissues.

The percentage of collagen in the catgut suture often determines the quality of the suture. Higher percentages of collagen allow for: superior tensile strength, longer absorption times, and lower reactions in vivo.

- highest quality collagen, maintaining a composition of 97% - 98% of pure collagen.

- DemeTech's Plain Catgut is rapidly absorbedz.

- Tensile Strength is maintained for about 10 days.

- Absorption is complete within 70 days.
