Why I like theDEVAX AXXESS stent … Dr. Christophe Dubois University Hospital Leuven Belgium
The holygrail of dedicatedbifurcationstenttechnology ? • Flexible sizing • Ease of use / predictable acute outcome • Conformance to vessel contour without disruption of the stent or coating • Preservation of the side branch • Single metal layer • Better long term outcomes /Enhanced safety • Cost/Benefit balance
AXXESS Stent • Nitinol material conforms to the anatomy of the vessel/lesion • BA9 drug reduces restenosis in side branch • Allows optimal size selection and placement of additional stents • Easy delivery with fully compatible Rx catheter system
Delivery System Safety lock Sheath actuator Stent deployed by sheath retraction Sheath markers Flush port AXXESS stent The DIVERGE Trial
A self expanding stent can span both sides of the carina at once The flared distal end enhances this ability The nitinol material will conform to the shape of the bifurcation Two Vessel Coverage

Bare metal version of Axxess Stent • Safety and effectiveness study • Six-month follow-up completed AXXESSn = 43 • Evaluated drug-eluting Axxess stent to bare metal stent • Safety and effectiveness study • Follow up through 3 years complete AXXESS PLUSn = 139 • International safety and effectiveness study • Evaluated best practices from AXXESS PLUS • Follow up through 12 months complete DIVERGEn = 302 • Multi-center pilot study for Axxess Left Main stent • 12 months follow-up complete • Study showed potential for effective LMCA intervention AXXENTn = 33 AXXESS Clinical Experience Over 500 Patients Studied
AXXESS PLUS: Key Findings Lesion Success and Restenosis were improved by presence of SB stent: * Attainment of < 50% residual stenosis of the target lesion using any combination of percutaneous devices; † P = 0.003 vs. stent (DES) Grube E. et al, Am J Cardiol 2007;99:1671-97
Based on AXXESS PLUS findings, the Axxess procedure was modified to obtain an optimal outcome in the SB (<30% residual stenosis post procedure) Optimal Technique Pre Final
