Chronic Evaluation of Novel Pacemaker System

The Calyan pacemaker is a device designed for implantation in the chest below the xiphoid process, and includes a FlexArm containing stimulation and sensing electrodes. The Calyan pacemaker is implanted using a set of delivery tools and clipped onto the xiphoid process; the FlexArm electrodes are oriented to make contact with the pericardial surface of the heart. Pacing parameters are adjusted wirelessly with a tablet-based programmer that communicates with the Calyan pacemaker via secure Bluetooth.
