Total Endoluminal SFA Bypass Individual results may vary. 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. GORE, VIABAHN®, and designs are trademarks of W. L. Gore & Associates. © 2009 W. L.

Clinical Lessons Learned • Avoid non-compliant lesions • Ensure adequate inflow and outflow(e.g., at least one vessel run-off) • Correct sizing is key • Land device at least 1 cm into healthy vessel proximally and distally to the lesion • Every region pre-treated with Percutaneous Transluminal Angioplasty (PTA) needs to be covered by the device • During post dilatation, only balloon inside the region covered by the device • Consider an antiplatelet regimen post-procedure GORE, VIABAHN®, and designs are trademarks of W.

GORE VIABAHN® Endoprosthesis with Propaten Bioactive Surface
Unique Bioactive HeparinBonding Technology • Heparin molecules are bonded directly to the surface of the endoprosthesis • Heparin is a polysaccharide anticoagulant with a long history of clinical use.1 • Heparin has a potent antiproliferative effect on vascular smooth muscle cells.2 • A Gore proprietary end-point attachment mechanism (CARMEDA® BioActive Surface Technology (CBAS®) allows for retention of bioactivity • The result is an endoprosthesis intended to provide sustained thromboresistance 1 Hirsh J, Anand SS, Halperin JL, Fuster V.

Unique Bioactive Heparin Bonding Technology Inside the microstructure ePTFE fibril Heparin molecule Bioactive heparin site Heparin molecules are bonded via end-point linkage mechanism to the surface of the endoprosthesis while retaining heparin’s activity. GORE, VIABAHN®, and designs are trademarks of W. L. Gore & Associates. © 2009 W. L. Gore & Associates, Inc.
Mechanism of Action • Heparin molecules are bonded to the endoprosthesis surface • Bioactive site of the heparin molecule binds to antithrombin (AT) • Antithrombin (AT) binds to thrombin (T) – a neutral AT-T complex is formed • Thrombin loses its ability to catalyze the conversion of fibrinogen to fibrin • Neutral AT-T complex detaches from the heparin molecule • Heparin bioactive site becomes available to again bind antithrombin GORE, VIABAHN®, and designs are trademarks of W.

Acute Thromboresistance GORE VIABAHN® Endoprosthesis with Propaten Bioactive Surface Control Endoprosthesis The bioactive luminal surface of a 5 mm diameter GORE VIABAHN® Endoprosthesis with Propaten Bioactive Surface appears free of thrombus after two hours in an in vitro blood loop model. The non-bioactive luminal surface of a control endoprosthesis (5 mm diameter) appears covered with thrombus after 90 minutes in the same blood loop model.

A New Beginning for the Proximal End New Contoured Edge
GORE VIABAHN® Endoprosthesis:Now with Contoured Edge • New precision laser trimming technology enables manufacturing change • Excess graft material is removed • Contoured trim is on proximal edge only GORE, VIABAHN®, and designs are trademarks of W. L. Gore & Associates. © 2009 W. L. Gore & Associates, Inc.
Reason for Modification • Improves device apposition to the vessel wall when oversizing prevents device expansion to its nominal diameter – Contoured edge may improve flow dynamics at proximal end GORE, VIABAHN®, and designs are trademarks of W. L. Gore & Associates. © 2009 W. L. Gore & Associates, Inc.

Summary of Modification • Result of a manufacturing change implementing laser edge trimming technology • Excess material at the proximal edge removed • The Instructions for Use, including sizing and placement recommendations remain unchanged • May improve the flow dynamics of blood entering the endoprosthesis GORE, VIABAHN®, and designs are trademarks of W.
