Barbed self-anchoring (knotless) suture
Monofilament suture with barbs cut into the strand's surface at regular intervals, designed to self-anchor into tissue without the need for knots; it is available in both absorbable and non-absorbable versions, with unidirectional or bidirectional barb patterns.
How it is used
Particularly useful in laparoscopic and robotic surgery for running closures (for example, fascia, vaginal cuff, myomectomy, or anastomoses), since it maintains tension along the suture line without an assistant holding it or the need for intracorporeal knot tying.
Clinical tip
The barbs allow the strand to slide in only one direction, so orientation must be watched during insertion to avoid premature or reversed anchoring; excessive tension can break the strand, and it typically costs more than an equivalent conventional suture.
