Biliary stent graft GORE® VIATORR® TIPS

ePTFE

The Gore Viatorr TIPS Endoprosthesis was created to effectively treat portal hypertension in both revision and de novo TIPS procedures. Physicians treating portal hypertension have been concerned about maintaining shunt patency, controlling syptoms, and minimizing complications, such as encephalopathy and liver failure following Transjugular Intrahepatic Portosystemic Shunt (TIPS) creation. The Gore Viatorr TIPS Endoprosthesis provides an innovtion solution for TIPS in both revision and de novo procedures. The proprietary, reduced permeability ePTFE graft lining minimizes transmural permeation of bile and mucin, which is a common causes of patency loss, and minimizes tissue ingrowth into the graft for ease of surgical dissection during liver transplantation. Additionally, it offers improved radial compression strength over the leading, commercially-available stents, and ensures secure anchoring with minimal kinking and tissue deformation. The unlined "chain link" segment of the device allows for nutrient portal perfusion. GORE® VIATORR® TIPS Endoprosthesis with Controlled Expansion combines the legacy of proven patency1 with diameter control to reach a targeted portal pressure gradient Control the diameter — Designed to reach a targeted portal pressure gradient Lasting diameter control*— Size and set the diameter to stay Engineered for flexibility — Conformability to tortuous anatomy
