Serafit® from Serag-Wiessner is a braided resorbable suture. It has at least 50% residual tensile strength after 14 days and is dissolved after approx. 90 days. It is available in 3/0 to 7/0 with different needles and thread lengths.

01

Material & structure

Polyglycolic acid (PGA), braided and coated multifilament. Violet USP 8/0–5 (EP 0.4–7), undyed USP 6/0–2 (EP 0.7–5).

02

Properties

Good knot stability, outstanding pliability and minimal "sawing effect" in the tissue.

03

Use & resorption

50% of tensile strength remaining after 15–20 days, full resorption after 60–90 days. Used for ligatures, dermatology, gastroenterology, gynecology, MIS, oral and maxillofacial surgery, ophthalmology and urology.

The differences between the threads and the needle codes are explained under sutures. See also resorbable sutures.

Resorbable sutures?

A suture's degradation rate is measured as strength versus half-life, so a figure of 5 days means at least 50% of the tensile strength remains after 5 days. The time until the suture has fully dissolved is usually much longer.

The times below are therefore half-lives.
