FDA Clears Varian’s Calypso Anchored Beacon Transponder
FDA has cleared a Varian 510(k) for its Calypso Anchored Beacon transponder. Used with Varian’s TrueBeam, Edge and Clinac C-series medical linear accelerators, the transponder detects slight movements of a tumor and helps clinicians deliver lung stereotactic body radiotherapy. The device is implanted in small airways within or near a tumor target so that the transponder can emit non-ionizing electromagnetic signals that are tracked in real-time and used to keep a treatment beam on target, according to the company.
