Deliver Superior Patient Outcomes*, 1-15

We believe in solid evidence

Backed by over ten years of clinical data and experience†,29

With its unique, dual-angle barb design, the V-Loc™ wound closure device is proven to improve patient outcomes*,3,16-18, while saving you time and money3,4,16-22

V-Loc™ Wound Closure Device

The V-Loc™ wound closure device is a revolutionary technology. Its uni-directional barbs close wounds securely without the need to tie knots.

  • Reduces the amount of suture material in the body due to the absence of knots16
  • Eliminates knots and consequently, the potential risks of knot-related complications2,31
  • Evenly distributes tension along the wound11,25
  • Resists migration and maintains tension of the suture line29
  • Delivers uncompromised tensile strength and improved wound healing with less ischemia2,26-28
  • May reduce surgical difficulty and minimally invasive surgery*,1,2,29
