Seralene® from Serag-Wiessner is a blue monofilament non-resorbable suture of polyvinylidene fluoride (PVDF) with a smooth, non-porous surface. It was developed for vascular surgery. It is available in 4/0 to 6/0 with different needles and thread lengths.

01

Material & structure

Polyvinylidene fluoride (PVDF), monofilament, blue. USP 8/0–2 (EP 0.4–5).

02

Properties

Lasting tensile strength, high knot security and virtually no "memory effect" after stretching.

03

Use

Non-resorbable and inert. Delivers the best results in vascular surgery and is also used for ligatures, microsurgery and plastic surgery.

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