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.

Leadless cardiac stimulation systems

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 electrodes that are implantable at sites proximate the myocardium using a percutaneous, transluminal, catheter delivery system. Each of the electrodes contains a source of electrical energy for pacing the myocardium and is adapted to receive electromagnetic energy from a source outside the myocardium. The system also includes a source adapted for placement outside the myocardium and that uses locally measured electrocardiograms to synchronize pacing of the heart by sending electromagnetic commands to the electrodes to pace the myocardium surrounding the electrodes. Also disclosed is various configurations of such systems, wireless electrode assemblies, and delivery catheters for delivering and implanting the electrode assemblies.

An apparatus for locally controlling smooth muscle tone includes a first electrode for insertion into an artery; a barrier for preventing the first electrode from contacting an arterial wall; a second electrode; a power supply; and a controller for coupling the power supply to the electrodes. The controller is configured to cause the electrode to maintain a waveform for controlling polarization of smooth muscle tone.

Control of arterial smooth muscle tone

Apparatus, system, and method that include a pacing apparatus having a stent electrode through which pulses of electrical current can be delivered. Stent electrodes receive energy for generating the electrical current from a variety of sources. Sources include from one or more induction coils that can form at least a portion of the stent. Sources can also include an implantable pulse generator coupled to a lead through which pulses of the electrical current are supplied to the stent electrodes.
