Hansen Medical, Inc. (NASDAQ: HNSN), a global leader in intravascular

robotics and the developer of robotic technology for accurate 3D

control of catheter movement, today announced that it has received

510(k) clearance from the U.S. Food and Drug Administration (FDA) for

its Magellan? Robotic System, including the catheter and accessories.

The Company will commence commercialization at selected centers in the

U.S. immediately, with a full launch expected later in the year. The

product will be presented at the 66th Vascular Annual Meeting of the

Society for Vascular Surgery at National Harbor, Maryland from June

7-9.

The Magellan Robotic System is intended to facilitate navigation to

anatomical targets in the peripheral vasculature and subsequently

provide a conduit for manual placement of therapeutic devices. The

System has the potential to provide vascular surgeons and other

interventionalists the ability to perform fast and predictable

procedures, while allowing the physician to be seated comfortably away

from the radiation source, which may reduce radiation exposure and

physician fatigue.

"Today's announcement marks one of the most significant milestones in

the Company's history," said Hansen Medical President and CEO Bruce

Barclay. "Not only does the Magellan System have the potential to be a

significant growth driver for Hansen, it also represents a fundamental

step forward in the transformation of vascular intervention using

intravascular robotics."

The global vascular market is large and expanding rapidly, driven by

an aging population, the prevalence of diabetes and obesity, and an

increase in disease awareness. Of the more than 3 million vascular

procedures done worldwide each year, approximately one-third to

one-half of them could be addressed using the Magellan Robotic System.

Dr. Alan Lumsden, Chair of Hansen Medical's U.S. Scientific Advisory

Board, and Chair of the Department of Cardiovascular Surgery and

Medical Director of Methodist DeBakey Heart and Vascular Center at The

Methodist Hospital, Houston, commented, "The Magellan Robotic System

is a significant technological advancement that may offer important

clinical benefits for physicians performing peripheral interventions.

The System provides physicians with independent robotic control of

both catheter tips to navigate efficiently through a variety of

anatomies and lesions. Our in vitro and in vivo animal studies

indicate that using this platform has the potential to increase

efficiencies in the interventional lab by shortening procedure times

and allowing more predictable interventions. Ultimately, we believe

this System may facilitate alternative patient treatment options by

enabling robotic endovascular interventions."

The Magellan Robotic System results in a new standard for peripheral

vascular intervention that has the potential to deliver revolutionary

lesion access, precise distal tip control, solid catheter stability

and consistent procedural efficiency.

Dr. Jean Bismuth, a leading vascular surgeon at the DeBakey Heart and

Vascular Center at The Methodist Hospital, Houston, said, "Since the

Magellan Robotic System was designed specifically for vascular

interventions, it offers excellent catheter stability and precision

during the delivery and placement of a variety of therapeutic devices

in different anatomic conditions, including various peripheral

vascular diseases with tortuous anatomy. Additionally, the Magellan

Robotic System may offer physicians less radiation exposure and

reduced procedural fatigue due to the remote workstation that allows

the physician to be seated comfortably outside the imaging suite."

The Company believes the Magellan platform also provides a compelling

value proposition to hospitals.

"Hospitals today need to ensure not only quality patient care, but

also sound fiduciary judgment in all purchase decisions," continued

Barclay. "To remain competitive in the markets they serve, hospitals

need to become more efficient, while also increasing their patient

capacity. The Magellan Robotic System has the potential to help

hospitals accomplish both of these goals."

"We are excited about the initial interest a number of key U.S.

hospitals have shown in the Magellan System and intend to focus our

near-term commercialization strategy on partnering with a select group

of esteemed physicians who are both influential and early adopters of

new technologies in the industry," said Barclay. "We will provide them

with the appropriate training and engage with them to demonstrate the

benefit and value of the Magellan. This focused and controlled

commercial launch should enable us to generate positive clinical

experiences and data to drive both interest and adoption among other

physicians and hospitals in the large and rapidly expanding U.S.

peripheral vascular market, and will be followed later this year with

full launch activities."

Barclay concluded, "Today's announcement is a testament to the

immensely talented development and support teams at Hansen Medical

that worked tirelessly to reach this important milestone, and I want

to personally congratulate and thank them for their hard work."

The Magellan System received a CE Mark in the European Union last

year, and the Company has already commenced a commercial launch in

that region. In addition, the System has been approved in Australia,

and is pending approval in Canada.

About the Magellan? Robotic SystemHansen Medical's Magellan Robotic

System is based upon the flexible robotic technology incorporated in

the Sensei-X@ Robotic Catheter System currently sold in the U.S. and

Europe, which has been used in more than 8,000 patients, but includes

a number of key enhancements. In particular, the Magellan Robotic

System:

Hansen Medical Conference CallCompany management will hold a

About Hansen Medical, Inc. Hansen Medical, Inc., based in Mountain

View, California, develops products and technology using robotics for

the accurate positioning, manipulation and control of catheters and

catheter-based technologies. The Company's Sensei@ X Robotic Catheter

System and Artisan Control Catheter were cleared by the U.S. Food and

Drug Administration for manipulation and control of certain mapping

catheters in electrophysiology (EP) procedures. This robotic catheter

system is compatible with fluoroscopy, ultrasound, 3D surface map and

patient electrocardiogram data. In the United States, the Sensei

System is not approved for use in guiding ablation procedures; this

use remains experimental. The U.S. product labeling therefore provides

that the safety and effectiveness of the Sensei X System and Artisan

Control Catheter 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 X System

and Artisan Control Catheter are cleared for use during EP procedures,

such as guiding catheters in the treatment of AF, and the Lynx@

Robotic Ablation Catheter is cleared for the treatment of AF. The

Company's Magellan? Robotic System, NorthStar? Robotic Catheter and

related accessories, which are intended to facilitate navigation to

anatomical targets in the peripheral vasculature and subsequently

provide a conduit for manual placement of therapeutic devices, have

undergone both CE marking and 510(k) clearance and are commercially

available in the European Union, and the U.S.
