Polyester Sutures and tapes

Product Detail

Polyester suture is a multifilament braided non-absorbable, sterile surgical suture which is available in green and white. Polyester is a category of polymers which contain the ester functional group in their main chain. Although there are many polyesters, the term “polyester” as a specific material most commonly refers to polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in the cutin of plant cuticles, as well as synthetics through step-growth polymerization such as polycarbonate and polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are non absorbable like the polyester suture.

Polyester Surgical Sutures are indicated for use in general soft tissue approximation and/or ligation, including use in cardiovascular, ophthalmic, and neurological procedures. Polyamide suture fibres are tough, possessing high tensile strength, as well as elasticity and lustre. They are wrinkle-proof and highly resistant to abrasion and chemicals such as acids and alkalis. Glass transition temp of polyamide is 47 °C. The suture is coated with silicone so that the tissue adherence to the suture is minimal.

Distinctive Characteristics of Polyester suture:

Polyester suture is a non-absorbable suture.

Braided to improvise the knot security.

Coloured green and white to differentiate between layers of knotting and differentiate b/w a stay and permanent suture.

High tensile strength

Coated with silicone.


A suture tape construct is made of braided high strength surgical suture material. A length of round braided suture extends along the entire length of the suture tape. A middle portion of the suture tape features a flat braid added to the round braided suture. The suture is incorporated centrally into the flat braid, providing a backbone to the construct. Transition sections at either end of the flat braid are tapered to allow the suture tape to pass easily through openings during surgical procedures. The suture tape is a braided construction of ultrahigh molecular weight polyethylene fiber blended with fibers of one or more long chain synthetic polymers, preferably polyester. The suture tape is indicated for high demand orthopedic repairs such as arthroscopic reconstruction for acromioclavicular joint separation, for example. The broad footprint of the suture tape is appropriate for repairs in degenerative cuff tissue where tissue pull-through may be a concern.

Polyester tape is non-absorbable, the retraction tape is for general use in retraction during surgical procedures. Composed of poly (ethylene, terephthalate), the tape is non-absorbable, braided for optimal handling properties and is available undyed (white).
