Leadless pacemakers are devices that are as small as a capsule and are small enough to allow the generator to be placed within the heart, therefore avoiding the need for pacing leads.<ref name=":0">{{Cite web|url=http://www.hospitalhealthcare.com/cardiology/leadless-pacemaker-new-era-cardiac-pacing|title=The leadless pacemaker: A new era in cardiac pacing|website=Hospital Healthcare Europe|language=en|access-date=2019-02-01|archive-url=https://web.archive.org/web/20190202041642/http://www.hospitalhealthcare.com/cardiology/leadless-pacemaker-new-era-cardiac-pacing|archive-date=2019-02-02|url-status=dead}}</ref>    As pacemaker leads can fail over time, a pacing system that avoids these components offers theoretical advantages.
