1. ECLIPSE Trial: Ensure’s Vascular Closure Device Speeds Hemostasis S. Chiu Wong MD Director, Cardiac Catheterization Laboratories New York Presbyterian Hosp.- Cornell Campus Professor of Medicine Weill Medical College of Cornell University SCAI / ACCi2 2008 Late Breaking Trial April 2 nd Chicago, IL

2. ECLIPSE Trial Eclipse ® Closure Device The investigational ExoSeal  device (Cordis, Miami FL) is a novel 3rd generation 6 Fr. extra- vascular closure device with a painless deployment mechanism that delivers a poly-glycolic acid (PGA) “felt-like” plug atop the femoral artery anchored by the neuro-vascular bundle sheath.

3. U.S. multicenter pivotal study comparing ExoSeal  and manual compression with 2:1 randomization was performed to assess the safety and efficacy of ExoSeal  in patients undergoing 6Fr. diagnostic and interventional coronary/peripheral procedures ECLIPSE Trial ECLIPSE Trial Design

4. Two primary effectiveness endpoints to be tested for superiority: –Time to hemostasis (TTH) –Time to ambulation (TTA) Primary safety endpoint to be tested for non- inferiority: –30-day combined rate of access site related complications including bleeding, infection, ischemia or injury requiring medical or surgical treatment ECLIPSE Trial Objectives

8. In this multi-center randomized trial in pts following 6 Fr. diagnostic/interventional procedures, a significant reduction in the TTH and TTA (primary effectiveness endpoints) was achieved in pts treated with the investigational ExoSeal  device compared with MC Device deployment was achieved promptly in about 1 minute on average following procedure There was no difference in procedural success rates in both the ExoSeal ® and MC groups Remarkably, there were no 30-day combined access site related complications (primary safety endpoint) reported in either treatment cohort Exoseal  is non-inferior to MC in composite major adverse event at the pre-specified 4% margin level Exoseal ® compares favorably to manual compression for arteriotomy site management post 6 Fr. invasive/interventional procedures.
