PALO ALTO, Calif., Jan. 24, 2013

PALO ALTO, Calif., Jan. 24, 2013 /PRNewswire/ -- Varian Medical Systems (NYSE:
VAR) has received FDA 510(k) clearance for the company's Edge™ radiosurgery
suite, a new dedicated system for performing advanced radiosurgery using
innovative real-time tumor tracking and motion management technologies.

"The Edge suite represents a new paradigm in radiosurgery, offering clinicians
a system that combines Varian's world-class technologies in an end-to-end
solution for planning and delivering radiosurgery treatments," said Chris
Toth, vice president of marketing for Varian's Oncology Systems business. "It
integrates Varian's state-of-the-art radiosurgery technology with tools for
real-time imaging, tracking, and patient positioning. It enables fast,
accurate delivery of stereotactic radiosurgery for treating lesions, tumors,
and conditions anywhere in the body where radiotherapy is indicated, including
tumors of the lung, prostate, spine and brain."

Recent FDA 510(k) clearances cover the following technologies that are
integrated into the Edge radiosurgery suite. These new technologies are also
being made available as upgrades to other compatible Varian systems:

  oThe PerfectPitch™ couch: An integrated six degrees of freedom (6DoF)
    treatment couch that provides the accuracy, precision, and flexibility
    needed to position patients optimally, adjust their position to correct
    for any misalignments, and support them comfortably during treatment. The
    PerfectPitch couch has been designed for the accuracy and functionality
    required to deliver radiosurgery treatments in the brain and in the rest
    of the body.

  oThe Advanced Motion & Image-Guided Radiotherapy (IGRT) package: An
    advanced motion management package that offers clinicians many options for
    using real-time imaging during radiotherapy treatments. It also enables
    expanded use of fluoroscopy and 4-D cone-beam CT—imaging techniques that
    show motion over time—to better compensate for tumor motion during
    treatment.

  oIntracranial radiosurgery package: An integrated set of technologies for
    planning and delivering stereotactic radiosurgery treatments for tumors or
    functional abnormalities in the brain. The intracranial radiosurgery
    package supports the accurate delivery of radiation using multiple beam
    shaping options, including Varian's high-definition multileaf collimator
    and radiosurgery conical collimators, and is compatible with both
    frame-based and frameless patient immobilization approaches.

  oCalypso system: Several enhancements have been incorporated into the
    Calypso system for real time tracking. The system utilizes transponders,
    or position signaling devices, that are implanted in or around a tumor, or
    placed on the surface of the body and monitored to track motion during
    treatment. New enhancements increase the rate of transponder signal
    processing in order to track faster types of motion, such as respiratory
    motion, in real time. The system is also compatible with the couch
    rotations that are often used to optimize targeting during treatments in
    the lung. The new system also includes updated usability features
    designed to streamline treatments and enhance the user experience.

One optional Edge suite subcomponent is still pending FDA 510(k) clearance:
Calypso anchored Beacon® transponders ^ for implantation in the lung to guide
lung radiosurgery procedures.
