Designed to expand to every demand, GORE® VIABAHN® VBX Balloon Expandable Endoprosthesis offers proven procedural success and long-term outcomes through flexibility, strength, and accuracy to treat iliac occlusive disease.
An Investigational Device Exemption (IDE) Clinical Study of the GORE® VIABAHN® Endoprosthesis with Heparin Bioactive Surface** in Japan demonstrated:
- 88% 12-month primary patency in long, complex SFA lesions (n = 103)1
- 21.8 cm average lesion length
- 65.7% chronic total occlusions (CTOs)
- 84.5% TASC II C&D lesions
** Heparin Bioactive Surface is synonymous with the CBAS Heparin Surface.
1. GORE® VIABAHN® Endoprosthesis Japan IDE Clinical Study demonstrated 12-month primary patency of 92% as defined by evidence of flow with no Target Lesion Revascularization (TLR). The same study demonstrated 88% 12-month primary patency when defined by PSVR of < 2.5 without a TLR.
