Polydioxanone Antibacterial Barbed Sutures

What Durabarb Plus Is

Durabarb Plus is a synthetic, absorbable surgical suture built on a monofilament polydioxanone structure. It is dyed violet for visibility against tissue and carries a triclosan antimicrobial coating, which is intended to inhibit bacterial colonization of the suture at the site of application. As an absorbable device, it is broken down within the body by hydrolysis rather than requiring later removal.

Barbed Construction

The distinguishing characteristic of Durabarb Plus is its barbed design. Instead of relying on terminal knots to hold tissue, the suture features barbs cut along its length that anchor into surrounding tissue as it is placed. The barbs are arranged in a 72-degree spiral pattern, which helps them engage tissue uniformly around the circumference of the suture. This knotless approach supports continuous, running closure and even distribution of tension along the wound.

Characteristics and Handling

Because closure is achieved without knots, there are no knot bulk or associated tension-monitoring steps at the suture ends. The suture demonstrates a Grade-1, slight tissue-reactivity profile. Its monofilament form and barbed anchoring make it suitable for continuous approximation of soft tissue, including situations where multiple layers may be closed with a single running suture. Needles supplied with Durabarb Plus are made from 300-series alloy steel.

Presentations

Durabarb Plus is offered in sizes 3-0, 2-0, 0 and 1. Configurations include unidirectional looped lengths (for example 15 cm, 23 cm and 30 cm loops) paired with 1/2-circle taper-point needles in lengths such as 26 mm and 37 mm, addressing a variety of procedural needs.
