Ethicon Johnson - NW5022 - Mersilk Sutures USP 8-0, 3/8 Circle Spatulated Micropoint NW5022 -12 Foils

This product is a non-absorbable surgical suture designed for delicate tissue approximation. It is constructed from natural braided silk, derived from the cocoons of the Bombyx mori silkworm. The suture is presented in a USP size 8-0, indicating a very fine diameter suitable for microsurgical applications.

The braided construction provides good handling characteristics and knot security. The silk filaments are coated with beeswax, which aids in smooth passage through tissue and reduces drag. This suture is intended for single use and is sterilized using radiation.

Each foil package contains 38 centimeters of suture material. The suture is black in color, facilitating visibility during surgical procedures. The product includes a precisely engineered needle for optimal performance.

The needle is 6 millimeters in length and features a 3/8 circle curvature. It is a spatulated micropoint needle, designed for precise entry and minimal tissue trauma, particularly in ophthalmic or other microsurgical fields. The needle is crafted from Ethalloy, a proprietary alloy known for its strength and durability.

The prolonged retention of tensile strength for approximately three months makes it suitable for procedures requiring extended support. This suture is intended for use by trained medical professionals in sterile surgical environments. It is commonly employed in ophthalmic surgery, plastic surgery, and other subspecialties where fine suture placement and minimal tissue reaction are paramount.

The non-absorbable nature means the suture will remain in place indefinitely unless removed, providing long-term tissue support. Careful handling and appropriate knot tying techniques are essential to ensure optimal wound closure and healing. The product is supplied in boxes containing 12 individual foil-wrapped sutures.
