Publication number: 20060161039Abstract: Just one embodiment of the invention includes a device, method and system for positioning a treatment instrument with respect to a patient. The novel device includes a holder for securing the treatment instrument (e.g., a magnetic stimulation device used for transcutaneous magnetic stimulation treatment of depression). The holder allows the treatment instrument to move about the patient. The device also includes a first arm that is coupled to the holder, and a vertical support that is coupled to the first arm. The first arm is substantially transverse to the vertical support, and may rotates about the vertical support in a horizontal axis. Such rotation, as well as movement and rotation of other components with respect to each other may be facilitated by a ball bearing construction.Type: ApplicationFiled: January 20, 2005Publication date: July 20, 2006Inventors: Vincent Juliana, Mark Riehl, Ravi Pillutla

Publication number: 20060122454Abstract: The invention is directed to a novel method for reducing discomfort caused by transcutaneous stimulation. The novel method includes providing transcutaneous stimulation, reducing the transcutaneous stimulation at a first location, and substantially maintaining the transcutaneous stimulation at a second location. The transcutaneous stimulation may be created by electric and/or magnetic fields. The first location may be relatively proximate to the cutaneous surface and may comprise tissue, nerves and muscle. Also, the second location may be relatively deeper than the first location and include, for example, brain tissue that requires the transcutaneous stimulation for treatment purposes. The invention further may include locating a conductor on a treatment area and/or a transcutaneous stimulation device relative to the first location. In addition, the method may further include adjusting how much the transcutaneous stimulation is reduced at the first location.Type: ApplicationFiled: October 25, 2005Publication date: June 8, 2006Applicant: Neuronetics, Inc.Inventors: Mark Riehl, Kenneth Ghiron

Publication number: 20060094924Abstract: A novel method and system for performing transcutaneous magnetic stimulation is disclosed herein. In the method, a first magnetic field is generated using a first magnetic stimulation device for transcutaneously stimulating a treatment area, and a second magnetic field for transcutaneously stimulating the treatment area is generated by a second magnetic stimulation device. In addition, a novel method and system for reducing discomfort caused by transcutaneous magnetic stimulation is disclosed herein. In the method, a first magnetic field is created at a first and second location using a first magnetic stimulation device. The first magnetic field causes magnetic stimulation at the first and second locations. A second magnetic field is created at the second location using a second magnetic stimulation device, thereby reducing stimulation at the second location.Type: ApplicationFiled: October 29, 2004Publication date: May 4, 2006Inventor: Mark Riehl

Publication number: 20050261542Abstract: The invention provides a method for treating a patient for mental illnesses, such as depression, by applying a magnetic field to the patient, producing a seizure in the patient as a function of a strength of the magnetic field, and preventing further stimulation from the magnetic field when the seizure is in progress. Such Magnetic Seizure Therapy (MST) does not include many of the known side effects of electroconvulsive therapy (ECT).Type: ApplicationFiled: May 24, 2004Publication date: November 24, 2005Inventor: Mark Riehl

Publication number: 20050234286Abstract: 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: ApplicationFiled: April 15, 2004Publication date: October 20, 2005Inventors: Mark Riehl, Kenneth Ghiron, Stanford Miller

Publication number: 20050148808Abstract: A device provides simple positioning of the patient's head and simple positioning of the TMS coil relative to a coordinate system of the patient's head once the head is positioned. The TMS coil is fixed at a treatment position in the coordinate system of the patient's head and the position in the coordinate system is recorded for use in subsequent clinical sessions. A positioner assembly supports the weight of the TMS coil and allows the operator to freely move the TMS coil to search for the patient's motor threshold position (MTP) and/or the treatment position (TXP). If the TXP is in registration with the MTP, once the MTP is determined, the positioner assembly requires only a single adjustment of the magnet position to locate the TXP where the coil is locked in place for the duration of the TMS therapy.Type: ApplicationFiled: January 6, 2004Publication date: July 7, 2005Inventors: Allan Cameron, John MacNeill, Gregg Flender, Mark Riehl

Publication number: 20050107654Abstract: Induced movement in a patient is detected and correlated with a TMS stimulating pulse so as to determine the patient's motor threshold stimulation level. Direct visual or audible feedback is provided to the operator indicating that a valid stimulation has occurred so that the operator may adjust the stimulation accordingly. A search algorithm may be used to direct a convergence to the motor threshold stimulation level with or without operator intervention. A motion detector is used or, alternatively, the motion detector is replaced with a direct motor evoked potential (MEP) measurement device that measures induced neurological voltage and correlates the measured neurological change to the TMS stimulus. Other signals indicative of motor threshold may be detected and correlated to the TMS stimulus pulses.Type: ApplicationFiled: November 17, 2003Publication date: May 19, 2005Inventor: Mark Riehl
