Product Name: GORE® VIABAHN® Endoprosthesis
GORE® VIABAHN® Endoprosthesis with Heparin BioActive Surface PMA Applicant: W.L. Gore & Associates, Inc.
Address: 3250 West Kiltie Lane Flagstaff, AZ 86001
Approval Date:
December 5, 2013
Approval Letter:

What is it? The GORE® VIABAHN® Endoprosthesis is a small, expandable, flexible, metal (Nitinol) tube shaped device (stent) that is lined with plastic (made from expanded polytetrafluoroethylene [ePTFE]).

The GORE® VIABAHN® Endoprosthesis with Heparin BioActive Surface is the same as the GORE® VIABAHN® Endoprosthesis, but it is coated with bioactive heparin, a chemical intended to reduce blood clots from forming.

Each stent is mounted on the end of a delivery catheter; a long, thin, tube-like device, and held in place by a release mechanism.

How does it work?

  • A catheter with a deflated balloon at its tip is inserted into a blood vessel in the groin and advanced within the vessel to an A-V access graft.
  • The balloon is inflated within the narrowed vein to open it (balloon angioplasty).
  • The balloon and its catheter are removed; then the stent and delivery system are advanced through the same vessel and positioned within the expanded vein.
  • The stent is then released (deployed) by retracting the outer tube (sheath) after it is positioned in the vein and opens automatically so that it is pressing against the A-V access graft and blood vessel.
  • The stent placement increases blood flow by holding the vein wall open.
  • Once the stent is deployed, the stent delivery catheter is removed.
  • The stent remains permanently implanted in the vein and acts as a support for the newly opened section of the vessel.

When is it used? The devices are used to treat narrowing or blockage in a blood vessel (stenosis) or a blood clot (thrombotic occlusion) that has developed where a vein and an arteriovenous (A-V) access graft connect, known as the venous anastomosis. An A-V access graft acts as an artificial blood vessel that goes between an artery and a vein and can be used repeatedly to draw blood with a needle during hemodialysis.

These devices are used instead of three other treatment options:

  • balloon angioplasty alone;
  • implanting other stent-grafts; or
  • surgery to remove the blockage.

What will it accomplish? Once in place, the stent acts as a scaffold to hold the vein open and restores blood flow at the venous anastomosis of an A-V access graft.

When should it not be used? Generally, patients who are not suitable candidates for balloon angioplasty are also not suitable candidates for stent placement.

The GORE® VIABAHN® Endoprosthesis with Heparin BioActive Surface should not be used in patients with known hypersensitivity (allergic reactions) to heparin, including those patients who have had a previous incidence of Heparin-Induced Thrombocytopenia disclaimer icon  (HIT) type II.
