Calypso Medical Technologies, Inc., Investigators Present Progress at AAPM 49th Annual Meeting

MINNEAPOLIS (BUSINESS WIRE) – July 22, 2007
Reports of scientific investigations of Calypso Medical’s Calypso® 4D Localization System™ will be presented at the American Association of Physicists in Medicine (AAPM) 49th Annual Meeting. These abstracts summarize initial clinical experiences with commercial installations of the Calypso System in radiation therapy.

Calypso Medical's platform is providing clinicians with a novel and effective way to setup patients for treatment and continuously track tumor motion during external beam radiation therapy that is very accurate and efficient. The company’s objective, real-time approach to clinical management of radiation therapy delivery is receiving high marks from the early users since its launch in January 2007. The company’s product platform has also received recognition from the Industrial Design Society of America’s IDEA™ Awards, co-sponsored by BusinessWeek®, for excellence in product design with a Gold Award on July 20, 2007.

Calypso Medical’s technology will be highlighted in six technical abstracts presented at the AAPM 49th Annual Meeting at the Minneapolis Convention Center in Minneapolis, Minnesota, July 22 – 27, and published simultaneously in the journal Medical Physics (Download Abstracts):

About Calypso® Medical
Calypso Medical Technologies, Inc. (“Calypso”) is a Seattle, WA based privately held medical device company. The Company’s proprietary tumor localization system utilizes miniaturized implanted devices (Beacon® electromagnetic transponders) to continuously, accurately, and objectively pinpoint the location of tumors for improved accuracy in radiation therapy. Calypso addresses two major issues in modern radiation oncology: errors in treatment set-up and tumor motion during treatment. In addition, the Calypso® 4D Localization System’s non-ionizing electromagnetic guidance has the potential to improve work flow efficiency and treatment room utilization. The technology is designed for body-wide cancers commonly treated with radiation therapy, including prostate, breast, lung, head, neck and other radiation therapy target organs. The product platform is currently FDA 510(k) cleared for use in the prostate.
