Dolphin Sutures manufactures Polydioxanone barbed suture, which is a knotless wound closure device, sterile synthetic absorbable monofilament suture made from the poly (p-dioxanone).
The empirical formula of the polymer is (C4H6O3) n Polydioxanone polymer has been found to be non-antigenic, non pyrogenic and elicits only a slight tissue reaction during absorption. Polydioxanone sutures are dyed by adding D & C violet no 2 (Colour index number 60725) during polymerization.
The barbed design evenly distributes tension offering a unique combination of security and speed—increasing both efficiency and value. With barbs on its surface at an angle of 72 arranged in a spiral manner, the barbs are arranged in a unidirectional or bi directional manner.
Bi-directional is a double-armed suture. Barbs reverse direction at the mid-point of the suture. Uni-directional Barb is a single armed suture. The unidirectional barbs have a terminal loop. The suture is anchored using the adjustable loop at the apex of the wound.
