Serasynth LOC Barbed Suture

Tissue closure of the latest generation

SERASYNTH LOC is an absorbable suture featuring monodirectionally aligned barbs at regular intervals. The beginning of the thread is welded to form a stable loop, creating a knotless anchor fixation system that distributes tension evenly along the suture for increased closure safety.

Serasynth LOC Barbed Suture
INDICATIONS & USE

Knotless closure across a wide range of specialties

SERASYNTH LOC provides knotless tissue closure across the following surgical fields:

  • Ligatures
  • Dermatology
  • Vascular surgery
  • Orthopaedics
  • Plastic surgery
  • Gynaecology
  • Urology
  • Minimally invasive surgery (MIS)
  • Laparoscopy
  • Urogynaecology

Minimum 65% tensile strength is retained at day 14; the absorption process is completed after approximately 180–220 days.

BARB TECHNOLOGY

Secure fixation without knots

The barb technology eliminates the need for a traditional starting knot and distributes tension evenly along the suture, increasing closure safety.

Welded Loop System

The thread's beginning is welded into a stable loop, creating a knotless anchor point.

Unidirectional Barbs

Unidirectional barbs at regular intervals provide secure tissue purchase.

Even Tension Distribution

Tension is distributed evenly along the suture, increasing closure safety.
