  • Patent number: 10799707
    Abstract: In an electrostimulator which applies electrical stimulation to patient tissue, measurements of lead impedance (tissue resistance), battery status, and like matters are used to format and/or truncate the ranges of programmable therapeutic output settings available for selection by a clinician. The clinician can therefore better tell whether chosen settings can actually be successfully implemented, and/or whether they may have adverse effects on device lifespan or patient safety.

  • Patent number: 10780285
    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.

  • Patent number: 10751003
    Abstract: Vital sign monitors are plagued by noisy photoplethysmography (PPG) data, making it difficult for the monitors to output consistently accurate readings. Noise in PPG signals is often caused by motion. The present disclosure provides improved techniques for reducing motion-related artifacts in optical/PPG measurements for vital signs monitoring. In general, techniques described herein are based on using measurements of reference sensors that include sensors other than optical sensors used for the optical measurements, e.g., biopotential sensors, bioimpedance sensors, and/or capacitive sensors. In particular, techniques described herein aim to filter PPG signals using substantially only the noise components of signals generated by reference sensors, by attenuating or altogether eliminating components of the signals generated by reference sensors which are indicative of the parameter the reference sensors are designed to measure.

  • Patent number: 10751535
    Abstract: Systems and methods provide stimulation of peripheral targets such as targets in the lower limbs. Electrode arrays realized in circumferential or longitudinal embodiments have pads with horizontal and/or vertical offsets. Electrode array geometries are customizable and adaptable to individual users and treatment of different disorders. Novel systems of customization include software and hardware implemented solutions. A single device can provide treatment of two or more disorders or unwanted states using selected electrode geometries and stimulation protocols. Systems and methods for assessment of candidate stimulation sites and protocols use subjective or objective measures or both to determine which meet stimulation success criteria. Simulation is provided using transcutaneous, percutaneous, or implantable stimulators. A main advantage is the improved treatment of pelvic floor disorders, and especially overactive bladder (OAB).

    Abstract: For example, one or more non-transitory computer-readable media includes executable instructions to perform a method. The method includes defining a plurality of spatial regions distributed across a geometric surface. At least one wave front that propagates across the geometric surface is detected based on electrical data representing electrophysiological signals for each of a plurality of nodes distributed on the geometric surface over at least one time interval. An indication of conduction velocity of the wave front is determined for at least one spatial region of the plurality of spatial regions during the time interval based on a duration that the wave front resides within the at least one spatial region. Slow conduction activity is identified for the at least one spatial region based on comparing the indication of conduction velocity relative to a threshold. Conduction data is stored in memory to represent each slow conduction event.
