LEADLESS TISSUE STIMULATION SYSTEMS AND METHODS
First Claim
1. A system for the delivery of antitachycardia pacing to a patient'"'"'s heart, comprising:
- one or more implantable receiver-stimulators adapted to contact one or more cardiac stimulation sites; and
a subcutaneously implantable acoustic controller-transmitter, wherein the controller-transmitter is adapted to transmit acoustic energy and the receiver-stimulator is adapted to receive the acoustic energy and convert the acoustic energy into cardiac stimulation energy based on both energy and signal information included in the received acoustic energy, and wherein the controller-transmitter is adapted to contain an electrogram signal processor and sensing electrodes for processing electrogram signals from the electrodes that are located on the exterior surface of the controller-transmitter and are in contact with tissue.

Abstract
Systems including an implantable receiver-stimulator and an implantable controller-transmitter are used for leadless electrical stimulation of body tissues. Cardiac pacing and arrhythmia control is accomplished with one or more implantable receiver-stimulators and an external or implantable controller-transmitter. Systems are implanted by testing external or implantable devices at different tissue sites, observing physiologic and device responses, and selecting sites with preferred performance for implanting the systems. In these systems, a controller-transmitter is activated at a remote tissue location to transmit/deliver acoustic energy through the body to a receiver-stimulator at a target tissue location. The receiver-stimulator converts the acoustic energy to electrical energy for electrical stimulation of the body tissue. The tissue locations(s) can be optimized by moving either or both of the controller-transmitter and the receiver-stimulator to determine the best patient and device responses.
