摘要： 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.

摘要： An apparatus for providing arrhythmia information uses an esophageal probe having a longitudinal axis oriented in the direction of the esophagus where it is intended to be lodged, the probe comprising at least three electrode portions spaced in the longitudinal esophageal direction of the probe. The apparatus comprises a control unit, wherein the electrode portions are connected to the control unit, wherein the control unit is configured to detect potential differences between different pairs of the electrode portions. The control unit is configured to determine a repeating heart beat pattern as basis for a time resolved determination of the potential in the direction of the longitudinal axis and possibly also a perpendicular axis of the esophageal probe using compressive sensing. The apparatus is configured to provide a plot with the representation of the activation map as observed on the posterior wall or any other wall of the heart.

摘要： An instrument for internal mapping includes a flexible elongated portion (702) and an expandable portion (710) coupled distally to the elongated portion, the expandable portion having one or more expandable loops. An array of sensors (706) and electrodes (708) is distributed on the expandable portion and is configured to concurrently register the instrument to real-time images of an anatomy using the sensors and measure electrical characteristics of the anatomy with the electrodes to generate an electro-physiology (EP) map having the anatomy and intensities of the electrical characteristics mapped together in the real-time images.

摘要： A method is proposed for determining a pulse rate through a sound-sensing means placed on an individual's trachea, the method comprising a preliminary step for recording sound signals for a lengthy duration, wherein it comprises subsequently the following steps: filtering digital signals representative of the sound signals by using an adaptive filter, applying a lowpass filter to the signals obtained in order to select the signals comprised in a specified passband, selecting a first temporal portion of filtered digital signals of a specified duration, intercorrelation with a temporal portion of filtered digital signals that follows the first temporal portion in time and is of a same duration, searching (4.6) for the intercorrelation, computing the time interval corresponding to this temporal position and computing the corresponding pulse rate throughout the recording duration, to obtain a temporal series of pulse rates S1.
