Patent number: 8177702Abstract: A proximity sensor for a transcranial magnetic stimulation (TMS) system detects the proximity of a TMS coil assembly to a position at which the coil is to receive pulses during TMS treatment and provides feedback to the operator so that the operator may adjust the TMS coil assembly as necessary to maintain optimal positioning during treatment. A flexible substrate containing a sensor or sensor array is disposed between the TMS coil assembly and the position such that the coupling of the TMS coil assembly to the position may be detected by the sensor(s). Sensor outputs are processed by signal processing circuitry to provide an indication of whether the TMS coil assembly is properly disposed with respect to the position during TMS treatment. A display may be used to provide an indication of how to adjust the TMS coil assembly to improve the positioning of the TMS coil assembly.Type: GrantFiled: April 15, 2004Date of Patent: May 15, 2012Assignee: Neuronetics, Inc.Inventors: Mark Edward Riehl, Kenneth Marc Ghiron, Stanford W.

Patent number: 8157718Abstract: The present invention relates to an electric circuit having a transformer capable of functioning as a buffer inductor, and a magnetic stimulator using the transformer. The electric circuit of the present invention includes a power supply unit, and rectification means for rectifying current from the power supply unit. A transformer has an inductor on a primary side connected to the power supply unit. A capacitor is connected to an inductor on a secondary side of the transformer. Reverse flow prevention means is connected in series between the capacitor and the transformer to prevent charges stored in the capacitor from reversely flowing toward the transformer. A discharge inductor receives charges stored in the capacitor as discharge current and forms a magnetic field. First switching means turns on or off flow of the discharge current that flows in one direction. Bypass means causes current to flow in one direction.Type: GrantFiled: November 26, 2005Date of Patent: April 17, 2012Assignee: MCube Technology Co., LtdInventors: Jeong-Han Yi, Jung-Hoe Kim, Soo-Yeol Lee, Min-Hyoung Cho

Patent number: 8140169Abstract: An induction heating apparatus includes a first interventional device and a second interventional device. The first interventional device includes an electrically conductive material. The first interventional device is adapted for implantation inside a body and for receiving an alternating current. The second interventional device comprises a magnetically conductive material. The second interventional device is adapted for implantation inside the body in close proximity to the first interventional device. With both devices placed inside the body, the second interventional device magnetically couples with the first interventional device and the second interventional device generates heat upon the application of the alternating current to the first interventional device thereby heating the body site.Type: GrantFiled: April 5, 2005Date of Patent: March 20, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Barry N. Gellman, Jozef Slanda, Kimberly Paddock

Patent number: 8140168Abstract: A transcutaneous energy transfer system, transcutaneous charging system, external power source, external charger and methods of transcutaneous energy transfer and charging for an implantable medical device and an external power source/charger. The implantable medical device has a secondary coil adapted to be inductively energized by an external primary coil at a carrier frequency. The external power source/charger has a primary coil and circuitry capable of inductively energizing the secondary coil by driving the primary coil at a carrier frequency adjusted to the resonant frequency to match a resonant frequency of the tuned inductive charging circuit, to minimize the impedance of the tuned inductive charging circuit or to increase the efficiency of energy transfer.Type: GrantFiled: April 30, 2004Date of Patent: March 20, 2012Assignee: Medtronic, Inc.Inventors: David P. Olson, Andrew L. Schmeling, Steven J. Nelson

Publication number: 20120065456Abstract: The invention includes a method of treating and preventing a neurological disorder, such as Alzheimer's Disease, in a subject in need thereof by positioning an electromagnetic field emitting source proximal to the subject and exposing the subject to an electromagnetic field having a predetermined frequency for a predetermined absorption period. Preferably, each individual treatment (comprising exposure to the predetermined frequency for the predetermined absorption period) is continued at a predetermined schedule (preferably daily) for a predetermined treatment period. The predetermined frequency, according to a preferred embodiment, is about 918 MHz with a specific absorption rate (SAR) of about 0.25 W/kg+/?2 dB. The predetermined absorption period of this preferred embodiment is about one hour. The treatment period is long-term, being greater than about 6 months and preferably between about 7 and 9 months.Type: ApplicationFiled: September 12, 2011Publication date: March 15, 2012Applicant: UNIVERSITY OF SOUTH FLORIDAInventors: Gary W.
