ELEKTA’S RADIOSURGERY SOLUTIONS ON CENTER STAGE AT 2009 CONGRESS OF NEUROLOGICAL SURGEONS ANNUAL MEETING EXTEND RECEIVES FDA 510(K) CLEARANCE

PRESS RELEASE Stockholm, Sweden, October 23, 2009 At the 2009 Congress of Neurological Surgeons (CNS) Annual Meeting, October 24-28 in New Orleans, Louisiana, Elekta will demonstrate how its line of stereotactic solutions expand treatment capabilities and bring new hope for patients presenting serious conditions.

Topping the list of innovations is Extend™, a stereotactic treatment program that lets clinicians apply the power and precision of Gamma Knife® surgery to a broader class of targets, including certain cancers of the head and neck. Including a re-locatable frame and support for fractionated treatments, Extend provides cross functional advantages in both SRS and SRT for both neurosurgeons and radiation oncologists. Extend for Leksell Gamma Knife® Perfexion™ has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) and is now available in the United States. “When faced with lesions that are too large or too critically located to be safely treated in a single session, Extend enables clinicians to divide the radiation dose over multiple treatments,” says Mark Symons, Senior Vice President of Elekta’s Neuroscience Business Unit. “The system also includes a highly precise non-invasive fixation option, allowing clinicians to treat more patients with greater confidence.” Other meeting highlights This year Elekta marks 60 years since the stereotactic frame has been in clinical use, a development that led to modern radiosurgery. Using stereotactic methods, Elekta has been able to design and deliver highly technical solutions that offer new treatment possibilities for cancer and brain disorders, including: • Leksell Gamma Knife® Perfexion™, a fine-tuned radiosurgery tool that has the capability to treat multiple brain metastases in a single session, reducing the damage to healthy tissue that may limit future treatment options and allowing for concomitant chemotherapy for optimum primary tumor control. • Elekta Axesse™, a fully integrated stereotactic system that combines 3D target visualization at time of treatment, 6D sub-millimeter robotic patient positioning and high resolution beam shaping, making it a versatile treatment system perfectly suited for spine radiosurgery and neuro-oncology. • Elekta Neuromag®, a magnetoencephalography (MEG) that moves beyond conventional imaging and clinical neurophysiology tools to provide clinicians and researchers with precise millisecond resolution and accurate localization to open a new window into human brain activity. • Leksell Stereotactic System®, a complete stereotactic system that offers the level of accuracy and reliability required to perform diagnostic and therapeutic procedures with absolute ease and confidence. • SonoWand Invite™ *, an intracranial, intra-operative imaging system that provides real-time image clarity and spatial accuracy throughout surgery, allowing the surgeon to perform complicated tumor resections and vascular procedures safely, and with confidence the job is complete. Elekta also plans to host an event in conjunction with the meeting.
