  • Patent number: 10987004
    Abstract: The invention provides a body-worn monitor that measures a patient's vital signs (e.g. blood pressure, SpO2, heart rate, respiratory rate, and temperature) while simultaneously characterizing their activity state (e.g. resting, walking, convulsing, falling). The body-worn monitor processes this information to minimize corruption of the vital signs by motion-related artifacts. A software framework generates alarms/alerts based on threshold values that are either preset or determined in real time. The framework additionally includes a series of ‘heuristic’ rules that take the patient's activity state and motion into account, and process the vital signs accordingly. These rules, for example, indicate that a walking patient is likely breathing and has a regular heart rate, even if their motion-corrupted vital signs suggest otherwise.

  • Patent number: 10966754
    Abstract: An apparatus for delivering an electrical microstimulator having a microstimulator body comprises a handle having a handle body. An elongate delivery rod includes a delivery sleeve and a stretching shaft, with one of the delivery sleeve and the stretching shaft configured for reciprocal movement with respect to the handle body, and the other extending longitudinally from, and stationary relative to, the handle body. The delivery sleeve selectively engages a fixation aperture of a microstimulator docking feature having a fixation base and a fixation member, concurrent with the stretching shaft engaging a proximal end of the microstimulator body. Longitudinal motion of the delivery sleeve with respect to the stretching shaft causes longitudinal motion of the fixation base to responsively move the fixation member between substantially linear and substantially coiled states. A method of delivering an electrical microstimulator to a target implant site of a patient's body is also provided.

  • Patent number: 10960205
    Abstract: An electric treatment device includes an impedance detector to measure bioelectrical impedance at a site of a body of a user by using electrodes in contact with the site, a voltage controller to perform treatment of the site by controlling a voltage applied to the electrodes, and a timer to set a target time from when treatment of the site is started by the voltage controller to when the voltage value of the applied voltage reaches the target voltage value, based on the measured bioelectrical impedance. The greater the measured bioelectrical impedance is, the shorter the timer sets the target time. The voltage controller increases the voltage value of the applied voltage to the target voltage value based on the set target time.

  • Patent number: 10912942
    Abstract: An implantable pulse generator (IPG) is disclosed having an improved ability to steer anodic and cathodic currents between the IPG's electrodes. Each electrode node has at least one PDAC/NDAC pair to source/sink or sink/source a stimulation current to an associated electrode node. Each PDAC and NDAC receives a current with a magnitude indicative of a total anodic and cathodic current, and data indicative of a percentage of that total that each PDAC and NDAC will produce in the patient's tissue at any given time, which activates a number of branches in each PDAC or NDAC. Each PDAC and NDAC may also receive one or more resolution control signals specifying an increment by which the stimulation current may be adjusted at each electrode. The current received by each PDAC and NDAC is generated by a master DAC, and is preferably distributed to the PDACs and NDACs by distribution circuitry.
