HNSN Hansen Medical, Inc. (MM)

Hansen Medical, Inc. (NASDAQ: HNSN), the global leader in flexible robotics and the developer of robotic technology for accurate 3D control of catheter movement, today announced preliminary revenue results for the fourth quarter of 2008 and provided a preliminary 2009 outlook.

For the fourth quarter, Hansen Medical shipped 11 Sensei systems and expects to recognize revenue on the sale of 10 systems. The eleventh system shipped in the fourth quarter should be recognized as revenue in the first quarter of 2009. For the full 2008 year, the company expects to recognize revenue on 40 systems. The lower than expected system sales were due primarily to the sluggish global macroeconomic environment and credit tightening that resulted in a number of potential customers postponing orders for the company's Sensei systems.

"The economic downturn and its effect on our customers' capital spending has been more dramatic than we anticipated when we provided our fourth quarter and full year outlook for system sales," said Frederic Moll, M.D., co-founder and chief executive officer of Hansen Medical. "As economic conditions continued to deteriorate during the fourth quarter, several potential customers who appeared to be on track to purchase Sensei systems during the quarter postponed their orders due to capital spending constraints. While this will impact our near term operating results, I remain confident in our ability to grow our business going forward. We are not aware of any of these delayed fourth quarter orders having been cancelled, but instead believe they remain under consideration for future purchases. In addition, I continue to be impressed with the enthusiasm expressed for our technology by clinicians who indicate they are better able to perform complex interventional procedures using the Sensei system. I also believe Hansen Medical's superior value proposition gives us a competitive advantage over our primary competitor whose system requires a significantly larger up-front investment," said Dr. Moll.

The company expects 2008 fourth quarter revenues to be in the range of $7.1 million to $7.4 million. In addition to the 10 Sensei systems, revenues for the quarter are expected to include the shipment of approximately 520 Artisan catheters. The expected range and components of 2008 fourth quarter revenue are estimates pending the audit of the company's financial results for the year ended December 31, 2008 and accordingly are subject to change.

Hansen Medical currently expects to recognize revenue on 53 to 65 systems for 2009. "Among other factors, this range takes into account the uncertainty around the length and severity of the current economic recession and the impact it will have on our potential customers," said Dr. Moll.

Hansen Medical will provide complete financial results, including an update on its outlook for 2009, in its regularly scheduled 2008 fourth quarter and full year press release and conference call. The exact timing and details of this press release and conference call will be announced in the near future.

About Hansen Medical, Inc.

Hansen Medical Inc., based in Mountain View, Calif., develops products and technology using robotics for the accurate positioning, manipulation and control of catheters and catheter-based technologies. Its first product, the Sensei(TM) Robotic Catheter system, is a robotic navigation system that enables clinicians to place mapping catheters in hard-to-reach anatomical locations within the heart easily, accurately and with stability during complex cardiac arrhythmia procedures. The Sensei system is compatible with fluoroscopy, ultrasound, 3D surface map and patient electrocardiogram data and was cleared by the U.S. Food and Drug Administration (FDA) in May 2007 for manipulation and control of certain mapping catheters in Electrophysiology (EP) procedures. The safety and effectiveness of the Sensei system for use with cardiac ablation catheters in the treatment of cardiac arrhythmias, including atrial fibrillation (AF), have not been established. In the European Union, the Sensei system is cleared for use during EP procedures, such as guiding catheters in the treatment of AF. Additional information can be found at www.hansenmedical.com.
