Abstract
Various configurations of systems that employ leadless electrodes to provide pacing therapy are provided. In one example, a system that provides multiple sites for pacing of myocardium of a heart includes wireless pacing electrode assemblies that are implantable at sites proximate the myocardium using a percutaneous, transluminal, catheter delivery system. Also disclosed are various configurations of such systems, wireless electrode assemblies, and delivery catheters for delivering and implanting the electrode assemblies.

16. A leadless pacing electrode assembly comprising:
-
a passive wireless receiver;
first and second electrodes attached to the passive wireless receiver to deliver the excitation pulses to the heart tissue when the passive wireless receiver receives energy from a magnetic field controlled by an external source, wherein the first and second electrodes are directly activated by the passive wireless receiver via an internal circuit that is free of a dedicated energy storage component; and
at least one fastener to penetrate through an interior surface of a heart chamber and into a myocardial wall, at least one of the first and second electrodes is positioned in the myocardial wall when the fastener penetrates through the interior surface of the heart chamber and into the myocardial wall. - View Dependent Claims (17, 18, 19, 20)
