Superior Control of Bleeding Wounds for Percutaneous Procedures

SyvekNT® contains poly-N-acetyl glucosamine (pGlcNAc) fibers, a polysaccharide polymer which promotes the rapid control of bleeding in patients on anticoagulation therapy. SyvekNT has proven to be effective for controlling bleeding in patients undergoing hemodialysis, and for management of bleeding wounds such as vascular access sites, percutaneous catheters or tubes and surgical debridement.

Applicable for All Cardiac Catheterization Procedures

In a published U.S. clinical evaluation of SyvekNT for 1,000 consecutive patients2:

  • Included stenting, PTCA, electrophysiology and diagnostic catheterization procedures
  • Catheter sheaths ranged from 4-12 French
  • 76% of interventional patients sheaths were pulled with ACTs > 200
  • < 1.5% minor complications

Can Safely Reduce Time to Ambulation

Clinical Evidence: In a U.S. study of 200 patients undergoing a diagnostic coronary angiography using 6Fr catheters1:

  • 98% were able to safely ambulate after one hour of bedrest
  • No major adverse events and only 2% minor adverse events*
  • Shortened bedrest may improve patient satisfaction
  • May improve catheterization laboratory efficiency

Easy to Use and Apply

SyvekNT® is a soft, white, sterile non-woven pad of poly-N-acetyl glucosamine fibers isolated from microalgae. The 3 cm x 3 cm dressing is attached to medical-grade foam backing and stored in a sterile, single-use package.

Instructions for Use

  • Open SyvekNT® and deliver it to the sterile field.
  • Hold occlusive pressure proximal to the puncture site and remove the sheath.
  • Allow 1-2 drops of blood from site.
  • Immediately place SyvekNT over the puncture site and hold firm pressure, while continuing to hold proximal pressure.
  • Slowly decrease amount of proximal pressure after 4 to 6 minutes (3 – 4 minutes for diagnostic procedures) while continuing to apply firm compression over the puncture site.
  • Hold firm pressure on the puncture site until bleeding is controlled, then slowly release.
  • Assess the site without disturbing SyvekNT, then cover with a transparent dressing.

Removing SyvekNT®

  • Soak SyvekNT with water.
  • Gently peel off SyvekNT.
