Design of an ultra-low-power communication system for leadless pacemaker synchronization

Abstract : Our research focused on power optimized solutions for the communication between Leadless Cardiac Pacemakers (LCP) to allow a synchronized therapy among devices implanted in different cardiac chambers. A promising solution is the Intra-Body Communication (IBC), which uses biological tissues as transmission medium. The attenuation of the communication channels were characterized using an accurate torso model that has been verified by means of in-vivo experiments. An ultra-low power receiver has been designed in CMOS technology according to the sensitivity requirement coming from the intra-cardiac channel characterization. Moreover, a novel communication strategy has been proposed to minimize the power consumption of the receiver reducing the impact in terms of device longevity. The research results show the feasibility of a telemetry driven synchronization of LCPs, paving the way toward multiple-leadless pacemaker systems that might improve the quality of treatment of the bradycardia patients. This work was part of the WiBEC project. It is a multi-disciplinary project aiming to develop the wireless technologies for novel implantable devices.
