Publication number: 20120059433Abstract: Systems and methods are disclosed to enhance bone growth by stimulating bone sites for bone regrowth, fusion, or grafts. The invention uses electrical stimulation of the bone site, where vibrational energy from a source is received by an implanted device and converted to electrical energy and the converted electrical energy is used by implanted electrodes to stimulate the bone site. The vibrational energy is generated by a controller-transmitter, which could be located either externally or implanted. The vibrational energy is received by a receiver-transmitter, which could be incorporated into an orthopedic device, such as pin, cage, plate or prosthetic joint used for bone healing.Type: ApplicationFiled: November 9, 2011Publication date: March 8, 2012Applicant: EBR Systems, Inc.Inventors: Mark W.

Patent number: 7996087Abstract: 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.Type: GrantFiled: September 4, 2009Date of Patent: August 9, 2011Assignee: EBR Systems, Inc.Inventors: Mark W.

Publication number: 20110166620Abstract: Systems and methods are disclosed to stimulate brain tissue to treat medical conditions such as movement disorders, pain and epilepsy. The disclosed invention uses electrical stimulation of the brain tissue, where vibrational energy from a source is received by an implanted device and converted to electrical energy and the converted electrical energy is used by implanted electrodes to stimulate the pre-determined brain site. The vibrational energy is generated by a controller-transmitter, which could be either implanted or located externally. The vibrational energy is received by a receiver-stimulator, which could be located under the skull, within the brain, on the dura, or in the cranial space close to the brain. As a therapeutic treatment, the implantable receiver-stimulator stimulates the brain sites that are effective in altering brain activity.Type: ApplicationFiled: January 14, 2011Publication date: July 7, 2011Applicant: EBR Systems, Inc.Inventors: Mark W.

Patent number: 7890173Abstract: 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.
