This ETHILON™ Black Monofilament Non-Absorbable Microsurgical Suture, product code B7770, is engineered for ultra-fine tissue approximation where maximum precision, minimal tissue trauma and long-term tensile strength are essential.

Manufactured from non-absorbable nylon monofilament (Polyamide 6), ETHILON™ provides exceptionally smooth tissue passage, very low tissue reactivity and reliable knot security. The monofilament structure minimises drag while maintaining excellent handling characteristics in delicate microsurgical environments.

The USP 10-0 diameter is specifically indicated for ophthalmic and advanced microvascular procedures requiring extremely fine wound closure. The 12 inch (30 cm) strand length allows precise control and optimal manoeuvrability within confined operative fields.

B7770 is supplied double-armed (D/A) with two TG140-6+ taper point needles in a 3/8 circle curvature configuration. The taper point design supports atraumatic penetration of delicate tissue and enables balanced, symmetrical microsurgical closure techniques.

Sterile and single-use, this suture is supplied in a box of 12 sutures and is intended for specialist hospital and microsurgical applications requiring dependable non-absorbable micro-closure performance.
