This MERSILK® Silk Black / Ivy Braided Non-Absorbable Surgical Suture, model W505, is designed for dependable soft tissue approximation and ligation where controlled handling and strong knot security are essential. The sutures are manufactured from black and ivory braided natural silk fibres with a coated finish to enhance smooth tissue passage while maintaining superior tying characteristics.

The USP 4-0 (Metric 1.5) size offers fine tensile strength suitable for precise soft tissue closure and skin approximation. Each pack contains four 45 cm (18 inch) sutures, providing flexibility for multiple applications within a single sterile unit.

This product features a single FS-3 conventional cutting needle, engineered for precise penetration of tougher tissues. The conventional cutting geometry supports controlled tissue entry and consistent wound closure performance.
