Ethicon Johnson - W8321 - Prolene Sutures USP 5-0, 3/8 Circle Round Body Visi-Black Double Needle W8321 -12 Foils Box

This product is a sterile, non-absorbable surgical suture designed for approximation of soft tissues. It is constructed from a monofilament strand of polypropylene, a synthetic polymer known for its high tensile strength and inertness within biological tissues. The suture material is engineered to maintain its breaking strength indefinitely, making it suitable for applications where long-term tissue support is required.

The Visi-Black coloration of the suture enhances its visibility against the surgical field, aiding in precise placement and knot tying by the surgical team. Each unit is supplied with a double-armed needle, facilitating efficient suturing techniques. The needle is a 3/8 circle round body configuration, measuring 13mm in length, and features a Visi-Black coating.

This specific needle design is intended for use in procedures requiring a curved needle for navigating tissue planes. The suture diameter conforms to USP 5-0 standards, indicating a fine gauge suitable for delicate tissue closure. The product is provided in sterile, individual foil packaging, ensuring aseptic integrity until the point of use.

It is intended for single use only to prevent cross-contamination and maintain sterility. Storage recommendations include keeping the product in a cool, dry environment away from direct sunlight. Prior to administration, a thorough inspection of the packaging for any signs of compromise or damage is essential.

This suture is intended for use by qualified medical professionals trained in surgical techniques and suture handling. The polypropylene material is resistant to degradation by bodily fluids and tissues, contributing to its reliable performance in a variety of surgical settings. The monofilament structure minimizes tissue drag during passage and reduces the potential for bacterial harboring compared to multifilament sutures.

The Visi-Black coating on the needle further optimizes its performance by improving its tactile feedback and visual tracking during suturing. The 3/8 circle needle geometry is a common choice for general surgical closures and is well-suited for accessing deeper tissues or working within confined surgical spaces. The USP 5-0 size is appropriate for closing smaller incisions or approximating delicate structures where minimal tissue trauma is desired.

The non-absorbable nature of polypropylene means that the suture will remain in place permanently, providing continuous support to the healing tissues. This characteristic is vital in procedures where the integrity of the closure must be maintained over an extended period. The double-armed configuration allows for simultaneous suturing from two directions or for rapid advancement of the suture line without the need to re-thread the needle, thereby potentially reducing operative time.

The overall design and material selection aim to provide a secure and predictable wound closure with minimal inflammatory response.
