Company Now Shipping both M-Turbo and S Series S Series First Ultrasound Device to Offer Zero Footprint Option Mount Sinai to Receive First S Series Shipment

BOTHELL, Wash. - December 17, 2007 - Sonosite, Inc. (Nasdaq:SONO), the world leader in point-of-care, hand-carried ultrasound, today announced that it has begun worldwide shipments of its S Series™ ultrasound tools. Based on the company's fourth generation technology platform, the S Series product line combines the processing power, image quality and advanced data management features of Sonosite's newly introduced M-Turbo„¢ system with a customized user interface to address the specific needs of four clinical specialties. "Sonosite is the only company that has designed a system that can withstand rigorous use in the Intensive Care Unit (ICU),€™ said John M. Oropello, MD, FCCP, FCCM, Professor of Surgery and Medicine, Program Director, Critical Care Medicine and Co-Director, Neurosurgical €“ICU, Mount Sinai School of Medicine, New York.

"We evaluated a lot of machines and no one else has taken into account what critical care physicians need. Both the S-ICU and M-Turbo have superb image quality and are easy to clean; so essential to infection control. I can foresee the day when there will be an S ultrasound tool mounted by every bedside in the ICU." Receiving one of the first S Series units shipped internationally is Sir Charles Gairdner Hospital of Perth, Australia. "The S-Nerve offers a sleek, elegant design with a very simple user interface," said Consultant Anaesthetist, Dr. Graham Hocking, MBChB, DMCC, FRCA, FFPMANZCA.

"My students were finding their way around it in no time, freeing all of their concentration for scanning." The S Series product line includes the S-FAST„¢ for emergency medicine physicians, the S-Nerve„¢ for anesthesiologists, the S-Cath„¢ for interventionalists and the S-ICU„¢ for intensivists. Like Sonosite€™s M-Turbo system, which the company began shipping on December 5, the S Series devices deliver breakthrough image clarity and seamless connectivity for digital image export in a rugged, hand-carried product that can be mounted on a pole, wall or ceiling for zero footprint. Formally introduced in October 2007 at medical meetings and congresses, physicians have enthusiastically responded to the following features of the M-Turbo and S Series products:
  • Outstanding Image Quality €“ The M-Turbo system and S Series devices advanced processing power is 16x more powerful than its industry leading MicroMaxx® system, and utilizes the new, advanced SonoADAPT„¢, SonoHD„¢, and SonoMB„¢ technologies for dramatic improvements in image quality;
  • State-of-the-Art Connectivity €“ Sonosite engineers worked with Texas Instruments to integrate its DaVinci„¢ technology and Microsoft to integrate its Windows Embedded CE 6.0 operating system for seamless data transfer and connectivity. Clinicians can export images easily from the new products 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;
  • Unmatched Commitment to Clinical Education-- The Education Key„¢ program, new with the 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;
  • Designed for Point-of-Care Demands€“ Like Sonosite€™s earlier products, the M-Turbo and S Series, and their transducers are designed to withstand a 3-foot drop onto a hard surface, have sealed surfaces that can be wiped down with disinfectant and boot within seconds of a cold start; and
  • Landmark Warranty €“The M-Turbo and S Series products and transducers carry the same, unprecedented 5-year warranty that Sonosite introduced with the launch of the MicroMaxx system in 2005.
