| 20090264965 | OPTIMIZING SIZE OF IMPLANTABLE MEDICAL DEVICES BY ISOLATING THE POWER SOURCE - A wireless cardiac stimulation device comprising an implantable transmitter module housing a transmitter and a separately implantable battery module housing a battery for powering the transmitter and other device electronics via a subcutaneously routable electrical cable connecting the module is disclosed. The transmitter module contains a transmitter enclosure which comprises one or more ultrasound transducers. Having separate transmitter and battery modules allows implantation of the transmitter module closer to the target receiver implanted in tissue. A discrete battery module also enables easy replacement of the battery without disturbing the transmitter, which is highly desirable. | 10-22-2009 |
| 20090319006 | IMPLANTABLE TRANSDUCER DEVICES - Receiver-stimulators comprise a nearly isotropic transducer assembly, demodulator circuitry, and at least two tissue contacting electrodes. Use of near isotropic transducers allows the devices to be implanted with less concern regarding the orientation relative to an acoustic energy source. Transducers or transducer elements having relatively small sizes, typically less than ½ the wavelength of the acoustic source, enhance isotropy. The use of single crystal piezoelectric materials enhance sensitivity. | 12-24-2009 |

| 20100063562 | LEADLESS TISSUE STIMULATION SYSTEMS AND METHODS - 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. | 03-11-2010 |

| 20100286744 | METHODS AND SYSTEMS FOR HEART FAILURE TREATMENTS USING ULTRASOUND AND LEADLESS IMPLANTABLE DEVICES - The present invention relies on a controller-transmitter device to deliver ultrasound energy into cardiac tissue in order to directly improve cardiac function and/or to energize one or more implanted receiver-stimulator devices that transduce the ultrasound energy to electrical energy to perform excitatory and/or non-excitatory treatments for heart failure. The acoustic energy can be applied as a single burst or as multiple bursts. | 11-11-2010 |
