May 10, 2007 - Accuray Inc. recently announced that it has entered into an agreement with CyberHeart Inc. under which CyberHeart will use Accuray’s technology to develop a noninvasive method for performing cardiac ablation, a procedure used to destroy a small portion of the heart that is causing abnormal rhythms.
CyberHeart is exploring the use of Accuray's CyberKnife robotic radiosurgery system to generate these lesions noninvasively. The CyberKnife System's intelligent robotics, accuracy and tracking capabilities will be used to target the heart's affected tissue and create an ablation lesion.
Currently cardiac ablation is done during open-heart surgery or as a catheter-based procedure in which a catheter is inserted into a blood vessel up to the heart and radiofrequency energy is delivered. Cardiac ablation is most often used to create a lesion that that interferes with abnormal cardiac conduction, with the objective of treating cardiac arrhythmias.
