Covidien CS-425 Sofsilk 1 1X30" GS-21 Wax Coated Braided Silk BX/36

Covidien Sofsilk™ Braided Silk | Size 1 | 30" Length | GS-21 Needle | CS-425

The Covidien CS-425 Sofsilk™ is a premium non-absorbable suture composed of high-quality natural silk fibers. To overcome the inherent capillarity of raw silk, each strand is meticulously braided and treated with a proprietary wax coating. This process significantly reduces the "wicking" of fluids along the fibers and allows the suture to glide through delicate tissue with minimal drag, while preserving the legendary knot security that has made silk a surgical staple for decades.

As a Size 1 suture, the CS-425 offers substantial tensile strength, making it ideal for heavy-duty tissue approximation and ligation where long-term structural integrity is required.

Technical & Clinical Advantages

• Superior Handling & "Knot-Down": The braided construction of Sofsilk™ provides a unique tactile response, allowing the surgeon to feel the knot seating securely. The wax coating ensures that knots slide into place smoothly without "chatter" or premature locking.

• Atraumatic GS-21 Taper Needle: The 37 mm taper point needle is designed to pierce and spread tissue rather than cut it. This is critical for vascular and gastrointestinal applications where minimizing the needle-hole diameter is essential to prevent leakage or hemorrhage.

• Reduced Capillarity: The specialized wax treatment seals the interstices of the braid, preventing the migration of bacteria and fluids along the suture line—a common concern with traditional untreated silk.

• Exceptional Visibility: The deep black pigmentation provides stark contrast against both light-colored connective tissue and blood-filled surgical fields, facilitating fast and accurate suture placement.

• Permanent Tensile Support: As a non-absorbable material, Sofsilk™ maintains its physical integrity indefinitely (though it may encapsulate over time), making it suitable for ligatures and structural repairs that do not require biological absorption.

Applications

• General Surgery: Secure ligation of large vessels and deep fascia closure.

• Gastrointestinal Surgery: Seromuscular layering and anastomosis where high knot security is paramount.

• Cardiovascular & Thoracic: Specialized repairs requiring a flexible, high-strength non-absorbable anchor.

• Hernia Repair: Providing a permanent, high-tensile mesh or tissue anchor.

Condition & Quality Assurance

• Status: NEW — Factory Sealed & Sterile.

• Integrity: This medical supply is securely packaged within its original manufacturer's sterile barrier. Both the inner foil pouches and the outer box of 36 are intact, ensuring full sterile integrity and lot traceability for clinical use.
