UHMWPE Sutures

What DURAFIBR UHMWPE Suture Is

DURAFIBR is a sterile, non-absorbable, braided surgical suture composed of ultra-high-molecular-weight polyethylene (UHMWPE) with polyester. It is intended for general soft and hard tissue approximation and ligation wherever a non-absorbable suture is indicated. Because the material is not absorbed by the body, it is well suited to procedures requiring prolonged mechanical support, including orthopaedic, arthroscopic, shoulder, rotator cuff, knee, and ankle repairs.

Composition and Construction

The suture is built from braided UHMWPE combined with polyester, a long-chain linear polyethylene that enables high tensile and flexural strength for demanding wound closure. DURAFIBR is supplied undyed with a blue tracer for improved intraoperative visibility. A sturdy central core runs through the braid to act as a backbone, supporting knot tying and consistent handling. The construction delivers corrosion resistance and a low coefficient of friction.

Characteristics and Handling

DURAFIBR is a flexible, strong, abrasion-resistant suture with a lubricious braid that allows each knot to slide for smoother placement. Its combination of UHMWPE and polyester is intended to provide high tensile strength, durability, and reliable handling. The suture elicits minimal initial inflammatory tissue reaction and, being non-absorbable, maintains mechanical support over the long term. Standard flat, square ties with additional throws as clinically indicated help secure knots.

Presentations

DURAFIBR is available in gauge sizes 2-0, 2, and 5, in undyed and co-dyed versions, with or without permanently attached surgical needles of varying types and shapes. Needle options include 1/2 circle taper-cutting and cutting profiles at 23 mm and 37 mm needle lengths, with 90 cm suture lengths.
