Calypso Medical and Siemens Announce Innovative Product Development Collaboration Agreement

CONCORD, Calif. and SEATTLE, Sep 22, 2008 (BUSINESS WIRE) -- Calypso Medical Technologies, Inc. (Calypso Medical) and Siemens Healthcare today announced a product collaboration agreement that will begin to integrate Calypso Medical's real-time tumor tracking data with Siemens' linear accelerator products. The first application to be addressed under this agreement will include adaptive gating, the capability of automatically interrupting the radiation beam from a linear accelerator in response to patient motion, organ motion or tumor position.

Calypso Medical's GPS for the Body(R) technology uses tiny electromagnetic transponders placed in or around the tumor to provide precise, continuous information on the location of the tumor at all times during external beam radiation therapy. This real-time information is critical in cases where the tumor may move due to normal physiological processes or if the patient moves during treatment. These types of movement may cause the radiation to miss its intended target and hit adjacent healthy tissue. In contrast to other tumor targeting solutions, Calypso's GPS for the Body(R) technology provides continuous tumor position information, thereby optimizing the delivery of radiation to the tumor and minimizing misapplied radiation to normal tissue.
