What is it? The Mynx™ VCS is vascular closure system designed to seal a puncture site in the femoral artery and stop the bleeding after a cardiac catheterization procedure. The Mynx™ VCS uses a balloon catheter and a standard procedural sheath to deliver an extravascular, hydrogel sealant used to seal the puncture site.

How does it work?

  • Following the cardiac catheterization procedure, the Mynx™ VCS balloon catheter is inserted through the introducer sheath into in a blood vessel in the leg (the femoral artery) to temporarily stop bleeding at the puncture site.
  • They hydrogel sealant is injected through the introducer sheath at the puncture site and within the tissue tract that stops the bleeding and seals the access site.
  • Once sealed, the balloon catheter is deflated and removed along with the introducer sheath and manual compression is applied for 1-2 minutes to ensure bleeding stops.
  • The gel will absorb into the body within 30 days.

When is it used? It is used on patients who have undergone diagnostic or interventional endovascular procedures

What will it accomplish? The Mynx is indicated for use to seal femoral arterial access sites while reducing times to hemostasis and ambulation utilizing a 5F, 6F or 7F procedural sheath.
