4-0 Chromic Gut RB-1 27" 36/Box

Ethicon U203H Chromic Gut Suture

Product Overview

An absorbable, sterile surgical suture made of purified collagen derived from either the serosal layer of beef (bovine) or the submucosal layer of sheep (ovine) intestines. This chromic gut suture is processed with chromic salts to slow absorption and enhance wound support durability. The suture is a monofilament, single-use device.

Key Specifications

• Suture size: 4‑0

• Length: 27 inches (approximately 70 cm)

• Needle: RB‑1 taper‑point, ½‑circle curvature, approximately 17 mm needle length, silver-colored

• Quantity per box: 36 strands

• Color: Natural brown (undyed)

• Absorbability: Absorbable; retains wound support for up to 90 days in vivo

Intended Use

Designed for general soft tissue approximation and ligation, including ophthalmic and mucosal procedures. It is not intended for cardiovascular or neurological tissue applications.

Clinical Considerations

• Absorbable nature makes it unsuitable for wounds requiring long-term tensile support. Supplemental nonabsorbable sutures may be needed in certain cases.

• Not recommended for use in elderly, malnourished, or debilitated patients whose wound healing may be compromised.

• As with all collagen-based sutures, there is a potential for immunologic reactions (e.g., inflammation, granulation, fibrosis) in patients hypersensitive to collagen or chromium. Avoid use in contact with urine or bile to reduce risk of calculus formation.

• Do not resterilize; discard unused sutures once the package is opened.

Applications

• Skin closure, mucosal repair, and soft tissue ligation

• Ophthalmic procedures (e.g., conjunctival repair)

• Suitable for general surgery where short- to medium-term absorbable wound support is acceptable

Packaging & Ordering Information

• Model number: U203H

• Box quantity: 36 individual strands

• Sterile, disposable, latex-free, single-use design

Summary

Ethicon U203H Chromic Gut Suture combines consistent surgical performance with controlled absorption. Its 4‑0 gauge, 27‑inch length, and RB‑1 taper‑point needle enable precise handling for delicate soft tissue closure. Ideal for general surgical applications in healthy patients, particularly where absorbable monofilament closure is preferred.
