2. Product Overview Approved in June 2005, the GORE ® VIABAHN ® Endoprosthesis is the only stent-graft available in the US with an SFA, Iliac, and AV Access indication. GORE ®, VIABAHN ®, and designs are trademarks of W. L. Gore & Associates. © 2014 W. L. Gore & Associates, Inc. The GORE ® VIABAHN ® Endoprosthesis is indicated for improving blood flow in patients with symptomatic peripheral arterial disease in superficial femoral artery de novo and restenotic lesions up to 270 mm in length with reference vessel diameters ranging from 4.0 – 7.5 mm, in superficial femoral artery in-stent restenotic lesions up to 270 mm in length with reference vessel diameters ranging from 4.0 – 6.5 mm, and in iliac artery lesions up to 80 mm in length with reference vessel diameters ranging from 4.0 – 12 mm. The GORE ® VIABAHN ® Endoprosthesis is also indicated for the treatment of stenosis or thrombotic occlusion at the venous anastomosis of synthetic arteriovenous (AV) access grafts.

3. Restenosis can Occur within Minutes or Hours After a Successful Angioplasty Severe stenosis of cephalic vein Good result immediately after balloon angioplasty Restenosis 30 minutes later due to elastic recoil A C B This study is a representative case.

4. Total Endoluminal Bypass: Preventing In-Stent Stenosis The GORE ® VIABAHN ® Endoprosthesis covers and seals off the diseased and irregular tissue of the arterial wall. In contrast, a bare nitinol stent covers only a small portion of the diseased arterial lumen. Individual results may vary. GORE ®, VIABAHN ®, and designs are trademarks of W. L.

11. The Gore REVISE Clinical Study The Gore REVISE Clinical Study was a multicenter, randomized-controlled trial evaluating the safety and effectiveness of the GORE ® VIABAHN ® Endoprosthesis in treating stenosis or thrombotic occlusions of a synthetic arteriovenous (AV) access graft at the venous anastomosis.

12. Definitions Target Lesion Primary Patency: The time interval of uninterrupted patency from initial study treatment to the next access thrombosis or intervention performed on the target lesion. Circuit Primary Patency: The time interval from initial study treatment to the next access thrombosis or intervention performed within the vascular access circuit. Access Secondary Patency: The time interval from initial study treatment to abandonment of the vascular access circuit.

16. Primary Effectiveness Endpoint: The GORE ® VIABAHN ® Device group demonstrated statistical superiority over the PTA group in target lesion primary patency as determined by Kaplan-Meier estimates (p = 0.008).

17. Greater patency for both thrombotic and non-thrombotic patients The Gore REVISE Clinical Study Despite the reduced patency outcomes for thrombotic patients, no statistical difference was detected in terms of treatment effect of the GORE ® VIABAHN ® Device relative to PTA (p = 0.792).
