Read the full statement (107 words)

The Calypso system is intended for use as an adjunct in treatment planning and radiation therapy, to align and/or monitor the patient's position relative to the isocenter of a radiation therapy system. The Calypso system provides accurate, precise and continuous localization of a treatment isocenter by using two or more Beacon transponders.

Implanted Beacon transponders are indicated for use to radiographically and electromagnetically mark soft tissue for future therapeutic procedures.

Permanent Beacon transponders are indicated for implantation in the body, specifically in the prostate and peri-prostate tissue (i.e. prostatic bed), and in soft tissue to align and monitor the treatment isocenter in real time during radiation therapy.

Indications for use as stated in the FDA summary.
