Serafast® from Serag-Wiessner is a monofilament resorbable suture of polyglycolic acid-caprolactone, violet or undyed. It has at least 60% residual tensile strength after 7 days and is dissolved after approx. 90 days. It is available in 3/0 to 6/0 with different needles and thread lengths.

01

Material & structure

Polyglycolic acid-caprolactone (PGCL), monofilament. Violet USP 5/0–2/0 (EP 1–3), undyed USP 6/0–2/0 (EP 0.7–3).

02

Properties

Outstanding handling, excellent tissue glide and an optimal resorption profile.

03

Use & resorption

50% of tensile strength remaining after 8–13 days, full resorption after 90–120 days. Used for ligatures, dermatology, plastic surgery, urology, gynecology and skin closure.

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.
