Heartbeat-powered pacemaker may pave way for self-sustaining devices

Overview

A preclinical study demonstrates a leadless intracardiac pacemaker powered by energy harvested from cardiac motion.

Background

Leadless pacemakers are increasingly relevant in managing patients with cardiac implantable electronic devices, particularly those with complications from traditional systems. This study explores the feasibility of a novel energy-harvesting mechanism.

Data Highlights

Key Findings

• The leadless pacemaker generated sufficient electrical output to pace the heart using energy harvested from cardiac motion.
• In vivo testing showed stable pacing with heart rate increases from 92 to 100 bpm and 75 to 120 bpm.
• Electrical output remained stable after exposure to accelerated fatigue testing, simulating long-term use.
• The device was successfully implanted using standard clinical methods without complications.
• Chronic evaluation indicated preserved cardiac function and no significant adverse effects.

Clinical Implications

Further studies are necessary to evaluate long-term safety and performance in larger animal cohorts.

Conclusion

Further research is needed to confirm long-term viability.
