Meet the challenges of portal hypertension

For patients with portal hypertension, including those with variceal bleeding and refractory ascites, the GORE® VIATORR® TIPS Endoprosthesis has been improving patient outcomes for more than 20 years. The VIATORR® Device has proven patency1 and patients treated with the VIATORR® Device have a higher one-year survival than those treated with non-TIPS therapy.2-4

Purpose-built for TIPS

  • Controlled expansion sleeve is designed to provide intraoperative adjustability of the diameter between 8 mm and 10 mm.*
    • Designed to reach a targeted portal pressure gradient to meet the specific needs of the patient.
    • Lasting diameter control. Size and set the diameter to stay.*
  • Bile-resistant, ePTFE lining designed to sustain patency due to reduced in-stent stenosis.
  • Uncovered portion for sustained portal vein and shunt perfusion.
  • Optimized radial force and flexibility engineered for conformability in tortuous anatomy.

Covered stent grafts offer long-term patency, compared to bare metal stents

Studies reveal that, at the time of TIPS creation, ePTFE-covered stent grafts have shown improved patency, ascites control and rebleeding prevention, compared to bare metal stents.5-13

For patients undergoing TIPS placement, the Advancing Liver Therapeutic Approaches (ALTA) group recommends, "The use of an ePTFE-lined stent graft with controlled expansion, which allows the operator to tailor the amount of portosystemic shunting based on the indication, target gradient and patient comorbidities."2

Variceal bleeding outcomes

Early TIPS compared to drug therapy plus endoscopic band ligation (EBL) for variceal bleeding13

Red Circle indicating 86%

1-year survival following early TIPS procedure with the VIATORR® Device, compared to 61% 1-year survival following pharmacotherapy plus endoscopic band ligation (P < 0.001)†,13

Red Circle indicating 97%

1-year control of bleeding following early TIPS procedure with the VIATORR® Device, compared to 50% 1-year survival following pharmacotherapy plus endoscopic band ligation (P < 0.001)‡,13

Red Circle with a line indicating no increase

No increase in the risk of hepatic encephalopathy (28%), compared to 1-year hepatic encephalopathy (40%) following pharmacotherapy plus endoscopic band ligation (P = 0.13)13

Refractory ascites outcomes

Early TIPS compared to large volume paracenteses (LVP) and albumin for refractory ascites14

Improved survival. TIPS with the VIATORR® Device demonstrated higher transplant-free survival (93%), compared to large volume paracenteses (LVP) and albumin infusion (52%) (P = .003)12

* Based on benchtop data on file. Less than 0.25 mm increase in diameter (diameter expansion) demonstrated by a simulated 10-year period at physiologic portal pressures.

† For a combined group of patients with Child-Pugh C (CP-C) score ≤13 or Child-Pugh B with active bleeding (CP-B + AB) at diagnostic endoscopy.

‡ One-year actuarial probability of remaining free of failure to control bleeding and of variceal rebleeding.
