Sonosite Introduces Fourth Specialized Ultrasound Visualization Tool for Interventional Radiology and Cardiac Cath Labs BOTHELL, WA, October 29, 2007 - Sonosite, Inc. (Nasdaq:SONO), the world leader in hand-carried ultrasound, today introduced the S-Cath™ visualization tool, a specialized ultrasound device designed to meet the specific point-of-care imaging, cardiac ultrasound, and procedural guidance needs of interventional radiologists and cardiologists. With its user-centered design, the S-Cath tool provides interventionalists immediate access to the optimum image with a minimum of controls and knobs. Its available suite of curved, linear and phased array transducers cover a range of guidance for interventional procedures such as line placement, biopsy, dialysis access, stent placement, femoral and other vascular access and fluid drainage as well as abdominal and cardiovascular imaging applications.

With standard VESA® compliant mounting capabilities, the system offers a zero footprint option for crowded interventionalist suites and cath labs. It can be mounted adjacent to other imaging modalities and moved in and out of the physician€™s line of sight as needed. "I think it€™s fabulous," said Abbas Chamsuddin, MD, Associate Professor of Radiology, Director of Vascular and Interventional Radiology, Emory University Hospital, Atlanta. "It€™s like a miniature Cadillac. The S-Cath has everything you need €“ clarity, the picture of a big machine, the size of screen. Yet it€™s still small, portable and very movable. There€™s also a lot of leverage with its mounting capability. I can see this being mounted in the interventional suite for quick access.

" The S-Cath tool joins Sonosite€™s radically new S Series„¢ line of application-specific ultrasound products. In addition to the S-Cath, the S Series products include the recently introduced S-FAST„¢ tool for emergency physicians, the S-Nerve„¢ tool for regional anesthesiologists, and for the intensivist, the S-ICU„¢ tool. Each of these devices offers clinicians breakthrough image quality, exceptional connectivity, rugged construction and Sonosite€™s landmark five-year warranty with a user interface, software and controls specialized to address the specific point-of-care exams and procedures commonly performed in their respective clinical specialty.

A Rich and Compelling Feature Set Sonosite designed the S-Cath tool with the same form factor and functions that it built into all of the S Series devices. As Sonosite has launched the S Series products, the feedback from clinicians across the clinical specialties has focused on a common set of features:

  • Outstanding Image Quality €“ The S Series devices feature the advanced processing power of Sonosite€™s recently introducedM-Turbo„¢ system, which is 16 times more powerful than its industry leading MicroMaxx® system, and utilizes the new, advanced SonoADAPT„¢, SonoHD„¢, and SonoMB„¢ technologies for dramatic improvements in image quality;
  • Designed for the Clinical Environment €“ Clinicians need only to manipulate two knobs to get the image they need. Transducers, exam settings, software and algorithms are all specialized for the specific clinical application;
  • State-of-the-Art Connectivity €“ Clinicians can efficiently export images from the S Series tools to a USB storage device in standard PC formats -- MPEG4 (H.264), JPEG, HTML and BMP -- for review or storage on PC or Mac® computers. The S Series devices sport three high speed (480Mbps) USB 2.0 ports for quick and seamless data management to facilitate patient record keeping, diagnostic consultation, instruction and publishing;
  • Unmatched Commitment to Clinical Education-- The Education Key„¢ program, common to all S Series devices and the M-Turbo system, is a USB thumb drive that contains a combination of system operation video tutorials, application-specific video refresher programs that provide peer-to-peer instruction on how to perform specific exams and procedures, and an image reference library of application specific sonographic anatomy for comparison purposes;
  • Landmark Warranty €“ All S Series devices and transducers carry the same, unprecedented 5-year warranty that Sonosite introduced with the launch of the MicroMaxx system in 2005, and continued with the M-Turbo system in 2007.
  • Ready-When-You-Are Boot-Time -- When clinicians absolutely, positively need that image, the S-Cath, S-ICU, S-Nerve and S-FAST tools can be depended on to boot up in seconds from a cold start, every time.

"Interventionalists, intensivists, anesthesiologists, and emergency physicians all have highly specialized, goal-specific visualization needs," said Kevin M. Goodwin, CEO and President of Sonosite. "Whether looking for free fluid in the body, performing an interventional procedure or administering a nerve block, they don€™t have time to manipulate a lot of bells and whistles. The S Series line of tools is designed to allow the physician to focus on the image, not the machine. With a minimum of dials and buttons, the S-Cath, S-ICU, S-FAST, and S-Nerve tools are the most goal-directed devices in the marketplace, and we expect that the increased adoption of point-of-care visualization will improve patient care and clinical productivity in these demanding specialties."
