One Button User Interface, High Resolution Imaging International Shipments Begun

BOTHELL, WA - July 7, 2009 - Sonosite, Inc. (Nasdaq:SONO), the world leader and specialist in hand-carried ultrasound, today announced the introduction of its new 6 pound NanoMaxx™ ultrasound tool, the latest addition to Sonosite's suite of specialised products for point-of-care visualisation in medicine. Designed for diagnostic imaging, clinical assessment and procedural guidance at the hospital bedside and in the physician's office, the NanoMaxx system is the company's latest innovation in point-of-care user design and features one button system control.

Sonosite has begun deliveries to international customers and is waiting FDA 510(k) clearance to begin US customer shipments. "The NanoMaxx tool makes high quality ultrasound available to a much broader range of clinicians and applications, all of which can save time and money and improve patient safety," said Kevin M. Goodwin, Sonosite President and CEO. "The healthcare world is changing dramatically and the NanoMaxx is part of our continuing effort to make ultrasound a more affordable and useful tool in the world of medicine."

"The NanoMaxx system offers our gold standard durability and two-hour battery life along with image quality similar to our flagship M-Turbo® system. A fluid-resistant user interface makes the system easy to clean and disinfect, helping to address the growing concern over infection control. Designed and manufactured at Sonosite's headquarters in Bothell, Washington, USA, the NanoMaxx system and its transducers again offer our industry-leading 5-year warranty to deliver the lowest cost of ownership in ultrasound," Mr. Goodwin said.

One Button Technology Optimises Workflow
Based on Sonosite's 4th generation Turbo technology platform, the NanoMaxx system incorporates proprietary, advanced imaging algorithm technologies, including ColourHD™ to deliver exceptional image quality in a lightweight, rugged form factor. With a touch screen that responds easily to the tap of a finger, and one button optimisation, clinicians can readily acquire high resolution images to increase clinical productivity at the point-of-care. A system boot-up time of less than 20 seconds and long battery life further enhance workflow when using the NanoMaxx system.

Designed to Help Hospitals Meet New Standards of Care
Clinical studies have proven that bedside ultrasound increases the accuracy of interventional procedures and it is now recommended by two government-based agencies1 and three US medical societies.2 At introduction, the NanoMaxx tool is available with a complement of five transducers to support a wide range of examinations and procedures including thoracic assessment for haemothorax, hydrothorax and pneumothorax, vascular access, needle aspirations and injections, as well as abdominal, cardiac, nerve, OB/Gyn, musculoskeletal, small parts and vascular scanning. The clinical capabilities of the NanoMaxx will help eliminate the risk and cost of transporting patients to the imaging lab for many examinations and procedures.

Mount it. Carry it. Or Use it on a Stand
The small footprint of the NanoMaxx system, along with its space-saving solutions, enables seamless integration with a variety of exam-room configurations. It can be wall mounted, placed on an exam table, or used from a highly manoeuvreable stand. Physicians can easily carry the NanoMaxx tool from room-to-room, to a satellite office, the operating room or to a field site for immediate use.

Built to Last
The NanoMaxx system's highly integrated architecture and ruggedized design, including the industry's first elastomeric bumper for extra durability, allows it to be used in the most austere and demanding environments. A magnesium shell that is significantly stronger and lighter than plastic helps to protect the system against accidental droppage. As with all Sonosite systems, the NanoMaxx ultrasound tool and its transducers are built to withstand a one meter drop test.

Web-Based Demonstration and Purchasing Programme
Sonosite's One-to-One Purchase Programme further extends the cost saving advantages of the NanoMaxx ultrasound tool by replacing or complementing the traditional on-site, pre-sale demonstration with a personal phone consultation and webcast demonstration provided by a professional clinical sales consultant. Visit the NanoMaxx ultrasound tool website to learn more about Sonosite's newest system and to experience a personal, interactive product demo. In addition, Apple® iPhone™ and iPod™ mobile device users can view a video of the NanoMaxx system on Sonosite's new SonoAccess™ application.
