Leadless tissue stimulation systems and methods
First Claim
1. A system for stimulating cardiac muscle, said system comprising:
- a subcutaneously implantable controller-transmitter, wherein the controller-transmitter is present in a sealed case; and
an implantable receiver-stimulator adapted to contact a cardiac stimulation site, wherein the receiver-stimulator is present in a sealed case;
wherein the controller-transmitter is configured to detect a pacing signal from a separate cardiac pacemaker, wherein the controller-transmitter is adapted to transmit acoustic energy upon detecting the pacing signal; and
the receiver-stimulator is adapted to receive the acoustic energy and convert the received acoustic energy into cardiac stimulation energy based on both energy and signal information included in the acoustic energy.

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.
