Volcano Corporation Announces Agreement To Acquire AtheroMed

Company's Phoenix® Atherectomy System Expands Volcano's Portfolio Of Peripheral Therapeutic Devices

SAN DIEGO, May 27, 2014 — Volcano Corporation said today it has signed an agreement to acquire AtheroMed, Inc., a privately-held company that has developed the Phoenix® Atherectomy System used in the treatment of peripheral artery disease (PAD).

The Phoenix, which received 510(k) clearance in January 2014 and has a CE Mark, enables physicians to treat PAD with a low profile peripheral atherectomy catheter that continuously removes diseased material as it is debulked. The device has reimbursement in the U.S. and select countries in Europe.

Under terms of the agreement, Volcano will pay $115.0 million in cash at closing, which is expected to occur in the current quarter. In addition, Volcano will make a $15 million milestone payment if a Phoenix device currently before the FDA receives clearance by November 15, 2014. This application covers design for manufacturing improvements to the currently approved device. In addition, the agreement calls for potential future revenue-based milestone payments by Volcano to AtheroMed.

The Phoenix is a peripheral atherectomy system that has been designed to provide physicians with a safe, versatile, easy to use primary therapy for treating PAD to restore blood flow to the ankle and foot. The over-the-wire system uses a rotating, front-cutting element located at the distal tip of the catheter to shave material directly into the catheter. The debulked material is then continuously captured and removed by an internal Archimedes Screw running the length of the catheter. The device is available in multiple sizes to treat diseased vessels both above and below the knee.

It is estimated that the global atherectomy market is in the range of $350-$400 million and growing at least seven percent annually.

Scott Huennekens, president and chief executive officer, said, "The Phoenix System is a technology-leading device that enhances our presence in a growing peripheral market where we will be offering three highly differentiated therapeutic devices—the Phoenix, Pioneer Re-Entry catheter and Crux vena cava filter—the latter two of which we acquired in the past 18 months."

Huennekens said the company plans to initiate a limited market release of the Phoenix by the end of 2014 and a full market release in early 2015. The company plans to initiate manufacturing at AtheroMed's facility in Menlo Park, California, but will transition manufacturing activities to Volcano's manufacturing facility in Costa Rica in late 2015.

"Phoenix is a unique atherectomy device in that it continuously cuts, captures and clears debris without the need for capital equipment," said Neil Hattangadi, MD, Volcano's executive vice president, peripheral vascular and global clinical affairs. "Data from the pivotal Endovascular Atherectomy Safety and Effectiveness (EASE) study demonstrated a high level of safety and effectiveness, with 95.1 percent of the lesions treated achieving technical success and 94.3 percent of patients free from major adverse events at 30 days. We believe these kinds of results, combined with its ease of use and versatility in treating a broad range of lesion types and vessel diameters, position the Phoenix to achieve a significant market share position in PAD therapy, especially below the knee. Importantly, we see strong synergy with our peripheral IVUS (Intravascular Imaging), FFR (Fractional Flow Reserve) and SyncVision Co-Registration technologies that will provide compelling clinical value and differentiation in the atherectomy market," he added.
