Gore’s CBAS Heparin Surface, the proven heparin bonding technology for lasting thromboresistance, is used in many of our interventional and vascular surgery products. End-point covalent bonding keeps heparin anchored to the device, while the bioactive site remains free to interact with the blood to help prevent clotting.*

- Proven heparin bioactivity: Unmatched, persistent ability to take up antithrombin2,3*
- Proven lasting thromboresistance: Improved surface hemocompatibility resulting from heparin availability and bioactivity1,2,3,4,5*

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
