Patent number: 10076459Abstract: Methods and systems for lift monitoring are described. In one embodiment, a first operation signal may be received from a first relay coupled to an electro-mechanical patient lift when the electro-mechanical patient lift is being operated in a first position. A second operation signal may be received from a second relay coupled to the electro-mechanical patient lift when the electro-mechanical patient lift is being operated in a second position. A determination of whether a lift qualification threshold is met may be based on the receiving of the first operation signal and the second operation signal. An occurrence of a lift may be recorded when a determination is made that the lift qualification threshold is met. Additional methods and systems are disclosed.Type: GrantFiled: August 19, 2013Date of Patent: September 18, 2018Assignee: WESTROCK SOLUTIONS, LLCInventors: James D.

System and method for using impedance to determine proximity and orientation of segmented electrodes
Patent number: 10016594Abstract: A method for implanting a neurostimulation lead within a patient includes measuring impedances of electrodes on the lead in order to correctly position the lead relative to a target tissue region. The electrodes are circumferentially segmented electrodes that are spaced from each other about the longitudinal axis of the lead. When the difference between the impedances of the electrodes exceeds a threshold value, the lead is in the correct position. In accordance with another embodiment, impedance measurements are used to select which one of the electrodes is closest to the target tissue region. By determining which electrode has the highest impedance and which electrode has the lowest impedance, the type of tissue adjacent to each electrode can be determined based on the conductivity properties of the tissue. The target tissue region may be a spinal cord, a posterior longitudinal ligament, white matter, or gray matter.Type: GrantFiled: November 29, 2016Date of Patent: July 10, 2018Assignee: Boston Scientific Neuromodulation CorporationInventor: Kerry Bradley -
Patent number: 10010713Abstract: Disclosed herein is a method of treating a disease, comprising: (a) implanting an array of electrodes on one or more targeted nerves and/or targeted muscles; and (b) treating the disease by selectively stimulating the one or more targeted nerves and/or targeted muscles through electrical pulses delivered from the array. Also disclosed herein is a device, comprising a plurality of electrodes that have the capacity to be inserted in a facial nerve. Further disclosed herein is a method of treating facial paralysis and/or damage in a subject, comprising: (a) detecting the level of contraction of individual muscles on a healthy, non-paralyzed side of the face of the subject; and (b) treating facial paralysis by a direct targeted stimulation of the corresponding muscles or nerve fibers on a paralyzed side of the face of the subject.Type: GrantFiled: April 8, 2016Date of Patent: July 3, 2018Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventor: Harrison W.

Patent number: 10004898Abstract: A system and method to treat neuromuscular conditions, including spinal cord injury, by what is characterized as dipole (two point) cortico-muscular stimulation. Two-point stimulation, with oppositely charged electrodes, allows pulsed, direct current to pass through the cortico-muscular pathway. The electrodes are placed on nerves, muscles, or a combination of both, that are on opposite sides of the spinal column, forming a current that passes across the spinal column. Further, an active electrode can be placed on the spinal column and a reference electrode can be placed outside the central nervous system. These methods improve functional recovery of the motor pathway.Type: GrantFiled: May 25, 2016Date of Patent: June 26, 2018Assignee: THE RESEARCH FOUNDATION OF THE CITY UNIVERSITY OF NEW YORKInventors: Zaghloul Ahmed, Andrzej Wieraszko

Patent number: 9993651Abstract: A system for treating chronic inflammation may include an implantable microstimulator, a wearable charger, and optionally an external controller. The implantable microstimulator may be implemented as a leadless neurostimulator implantable in communication with a cervical region of a vagus nerve. The microstimulator can address several types of stimulation including regular dose delivery. The wearable charger may be worn around the subject's neck to rapidly (<10 minutes per week) charge an implanted microstimulator. The external controller may be configured as a prescription pad that controls the dosing and activity of the microstimulator.Type: GrantFiled: October 19, 2015Date of Patent: June 12, 2018Assignee: SetPoint Medical CorporationInventors: Michael A.

The apparatus for controlling smart wear includes a motion capture unit, an error information unit, a motion estimation unit, and an actuation unit. The motion capture unit captures a motion of a user using sensors included in the smart wear. Then error information unit generates user error information using reference motion information and the results of the motion capture. The motion estimation unit estimates a subsequent motion of the user using the user error information. The actuation unit controls the smart wear of the user in real time using the estimated subsequent motion and the user error information.Type: GrantFiled: January 23, 2014Date of Patent: June 5, 2018Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Hyung-Il Park, Byoung-Gun Choi, Sung-Weon Kang, Chang-Hee Hyoung, In-Gi Lim, Tae-Wook Kang, Jung-Hwan Hwang, Kyung-Soo Kim, Jung-Bum Kim, Sung-Eun Kim, Kyung-Hwan Park, Tae-Young Kang
