Packaging

CHROMIC GUT sutures are absorbable sterile surgical sutures composed

of purified connective tissue (mostly collagen) derived from the serosal layer

of beef (bovine) intestines. They are packaged in a solution of 89%

isopropanol, 10% water and 1% 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

Surface smoothness to facilitate knot run-down and

knot strength, due to electronic polishing of each strand.

CHROMIC 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.

The use of these sutures is contraindicated in patients with known

sensitivities or allergies to collagen or chromium, as gut is a collagen based

material and CHROMIC GUT is treated with chromic salt solutions.

CHROMIC GUT sutures elicit a minimal acute inflammatory reaction in tissues

characteristic of foreign body response to a substance. This is followed by

gradual loss of tensile strength and suture mass, as the enzymatic process

dissolves the surgical gut until it is completely absorbed.

Many factors may affect the rate of tensile strength loss. These include:

• Type of suture

• Presence of infection

• Tissue sites

Absorption of CHROMIC GUT sutures occurs by enzymatic process similar

to the digestion of an animal protein by the body. Being enzymatic, the

process is subject to different inﬂuencing factors (see above) and it is virtually

impossible to indicate the exact designation of a consistent absorption time.

Gamma irradiation

CHROMIC GUT absorbable sutures are available in USP and EP sizes 2

(6 metric) through 7-0 (0.7 metric). The sutures are supplied sterile,

in pre-cut lengths or ligating reels; non-needled or affixed to various

needle types, using both permanent and removable needle attachment

techniques; in one, two or three dozen boxes.
