The pulse applicator includes a first arm, including a first electrode, a second arm, including a second electrode, and a spacer. The first arm, the spacer, and the second arm are movably connected, and define a gap between the first arm and the second arm. The first electrode, the gap, and the second electrode are selectively alignable, and the first electrode and the second electrode are configured to deliver an electrical field across the gap in response to an electrical pulse received across the first and second electrodes.

A bio-electrical signal measurement and electrical stimulation device using skin resistance is provided. The biosignal measurement and electrical stimulation device includes: a pad in which a plurality of horizontal electrical wires and vertical electrical wires for electrical stimulation are formed to intersect at a constant gap; and a control module that is electrically connected to the pad to acquire body information of a patient by measuring a biosignal of intersections in which the horizontal electrical wires and the vertical electrical wires intersect and that enables generation of electrical stimulation while controlling power that is supplied to the horizontal electrical wires and the vertical electrical wires using the body information.

An apparatus for monitoring EMG signals of a patient's laryngeal muscles includes an endotracheal tube having an exterior surface and a first location configured to be positioned at the patient's vocal folds. A first electrode is formed on the exterior surface of the endotracheal tube substantially below the first location to receive EMG signals primarily from below the vocal folds. A second electrode is formed on the exterior surface of the endotracheal tube substantially above the first location to receive EMG signals primarily from above the vocal folds. The first and second electrodes are configured to receive the EMG signals from the laryngeal muscles when the endotracheal tube is placed in a trachea of the patient.

A device for providing a magnetic treatment by evoking muscle contraction by a time-varying magnetic field and providing a RF treatment by heating biological structure. The device includes an applicator having an RF electrode and a magnetic field generating device. The device may also include a main unit, a human machine interface, and a control unit. The control unit adjusts a signal provided to the RF electrode and controls an RF circuit, and also adjusts the signal provided to the magnetic field generating device and controls a magnetic circuit electrically insulated from the RF circuit. The RF circuit may include a power source and a power amplifier, and the magnetic circuit may include an energy storage device to supply the magnetic field generating device with electric current.

The present disclosure involves a method of entering data in a portable electronic device. A request is received from a healthcare professional to perform data entry in an input field. The request is received via a touch-sensitive user interface of the portable electronic device. In response to the request, a plurality of predefined suggestions is displayed as candidates for the data entry. A selection of one of the plurality of predefined suggestions by the healthcare professional is then detected. Thereafter, the selected predefined suggestion is automatically entered as the data entry in the input field.

An automated method of controlling neural stimulation. A neural stimulus is applied to a neural pathway in order to give rise to an evoked action potential on the neural pathway, and the stimulus is defined by at least one stimulus parameter. A neural compound action potential response evoked by the stimulus is measured. From the measured evoked response a feedback variable such as observed ECAP voltage (V) is derived. A feedback loop is completed by using the feedback variable to control the at least one stimulus parameter value for a future stimulus. The method adaptively compensates for changes in a gain of the feedback loop caused by electrode movement relative to the neural pathway. A compensating transfer function is applied to the feedback variable, the compensating transfer function being configured to compensate for both (i) a distance-dependent transfer function of stimulation, and (ii) a distance dependent transfer function of measurement which is distinct from (i).

Methods and systems for stimulating and monitoring electrogenic cells are described. Some systems for stimulating electrogenic cells are based on the injection of electric currents into the cells via electrodes connected to the cells. Such stimulators may comprise an impedance element having an input terminal and an output terminal coupled to an electrode, and a voltage follower coupled between the input terminal and the output terminal of the impedance element, the voltage follower being configured to maintain a substantially constant voltage between the input terminal and the output terminal of the impedance element. The impedance element may comprise one or more switched capacitors at least in some embodiments. In some embodiments, the voltage follower may be implemented using a source follower.
