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. [11] As pacemaker leads can fail over time, a pacing system that avoids these components offers theoretical advantages.
An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...
A UHS spokeswoman said: “The device, named the Aveir VR leadless pacemaker, is 10 times smaller than standard devices at 38mm and is used to correct slow heart rhythm, known as bradycardia.

HCN4 is the main isoform expressed in the sinoatrial node, but low levels of HCN1 and HCN2 have also been reported.The current through HCN channels, called the pacemaker current (I f), plays a key role in the generation and modulation of cardiac rhythmicity, [13] as they are responsible for the spontaneous depolarization in pacemaker action potentials in the heart.
St. Jude Medical was founded in 1976 to further develop bi-leaflet artificial heart valves, which were originally created in 1972 at the University of Minnesota. [4] [5] St. Jude Medical's bi-leaflet valve was developed in large part by Dr. Demetre Nicoloff of the University of Minnesota and St. Jude Medical employee Don Hanson.
