01
Material & structure
Polytetrafluoroethylene (PTFE), monofilament, undyed only. USP 7/0–2/0 (EP 0.5–3).
02
Properties
Lasting tensile strength, excellent glide, biologically inert, anti-adhesive and minimized memory effect.
03
Use
Non-absorbable and inert. Used for vascular and cardiac surgery as well as oral and maxillofacial surgery – also available as Chordae Loop for mitral valve reconstruction.
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.
