Patent number: 8862239Abstract: Selective high-frequency spinal cord modulation for inhibiting pain with reduced side effects and associated systems and methods are disclosed. In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 50 KHz may be applied to the patient's spinal cord region to address low back pain without creating unwanted sensory and/or motor side effects. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications.Type: GrantFiled: September 25, 2013Date of Patent: October 14, 2014Assignee: Nevro CorporationInventors: Konstantinos Alataris, Andre B. Walker, Jon Parker, Yougandh Chitre, Sangsoo Wesley Park, James R. Thacker

Publication number: 20140303685Abstract: A nerve stimulation system includes a pulse generator and implantable lead. The pulse generator includes a sensing module and a pace circuit. The lead has an electrode array near the distal end and a connector at the proximal end for connection to the pulse generator. Conductors in the lead electrically connect the electrode array with the sensing module and pace circuit. The electrode array includes a first pair of small electrodes and a large electrode close to each other. The small electrodes and large electrode are physically separated from each other by insulative spaces extending generally transversely to a longitudinal axis of the lead. When the conductors are in electrical communication with the sensing module and pace circuit, the first pair of small electrodes are in electrical communication with both the sensing module and the pace circuit and the large electrode is in electrical communication with the pace circuit only.Type: ApplicationFiled: June 20, 2014Publication date: October 9, 2014Inventors: Stuart Rosenberg, Cecilia Qin Xi

Patent number: 8855737Abstract: A system and method for electrically shielding a physiological pathway from electrical noise is disclosed. The method includes the operation of implanting at least one signal microelectrode into a patient such that the signal microelectrode is proximate to the physiological pathway. An additional operation includes substantially enclosing the microelectrode and a section of the physiological pathway with an electrical shielding wrap. The electrical shielding wrap includes a plurality of holes that enable fluid communication of physiological fluids between an inside and outside of the wrap.Type: GrantFiled: December 30, 2013Date of Patent: October 7, 2014Assignee: University of Utah Research FoundationInventors: Gregory Arthur Clark, David James Warren, Noah M. Ledbetter

Publication number: 20140257446Abstract: Disclosed is an electrode, such as an SCS paddle electrode, having a lead attached thereto along an interior portion of the electrode. The lead and electrode are configured such that the lead may be positioned generally coplanar with a top surface of the electrode, and may likewise be erected from such coplanar orientation up and away from the top surface of the electrode. Thus, the lead can maintain the typical configuration of emerging from the back end of the electrode, but because at least portions of the lead are not permanently bonded into the electrode paddle, the lead (when desired) can be pulled upward, with or without surrounding strain relief material, to emerge from the top surface of the paddle at an angle or curve to such top surface. This allows the base of the paddle to engage a bony opening, such as when the electrode is inserted into a patient's spine, skull, plane of fascia, etc.Type: ApplicationFiled: March 18, 2014Publication date: September 11, 2014Inventor: Richard B.
