Leadless tissue stimulation systems and methods
First Claim
1. A method for selecting and optimizing the implant locations of a controller-transmitter device and a receiver-stimulator device, said method comprising:
- (a) positioning a controller-transmitter at a remote tissue location;
(b) positioning a receiver-stimulator at a target tissue location;
(c) activating the controller-transmitter to deliver acoustic energy to the receiver-stimulator so that said receiver-stimulator delivers electrical energy into the target tissue location;
(d) observing a first response;
(e) repositioning at least one of the controller-transmitter and the receiver-stimulator and observing a subsequent response;
(f) comparing the first and subsequent response;
(g) determining whether the controller-transmitter and receiver-stimulator positions are satisfactory;
(h) repeating steps (e)-(g) until the controller-transmitter and receiver-stimulator positions are satisfactory;
(i) selecting the positions that are satisfactory; and
(j) implanting an implantable controller-transmitter device and the receiver-stimulator device at the selected positions.

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.
