The GORE® VIATORR® TIPS Endoprosthesis is an innovative solution for TIPS in both de novo and revision procedures. The proprietary, reduced permeability ePTFE graft lining minimizes transmural permeation of bile and mucin (which are 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.
