There is provided a system for managing reflux during an enteral feeding, comprising: (i) a non-transitory memory having stored thereon a code for execution by at least one hardware processor of a computing device, the code comprising: code for receiving electrical signals outputted by at least one reflux event sensor disposed within a digestive system of a patient; code for determining a gastric reflux event based on an analysis of the electrical signals; code for outputting instructions to pause enteral feeding of the patient by a feeding controller that regulates enteral feeding of the patient using an enteral feeding tube positioned within the digestive system of the patient; and (ii) an evacuation controller that directs back-flow of digestive contents from the digestive system of the patient to an external evacuation reservoir through an evacuation tube.

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.

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.

The invention relates to a diagnostic system for the simultaneous long-term registration of heart rate variability as well as the pressure value and/or the impedance and, if so desired, further measured values of a patient with a measuring probe system suitable for deriving data for electrocardiogram generation, a catheter for insertion into the esophagus of the patient, the catheter being provided with several measuring probes each for pressure determination and/or for impedance measurement, and, if required, further measuring probes for determining further measured values, a recording apparatus having a voltage source and a plurality of channels for the registration and recording of the measurement data originating from the measuring probes, at least one memory for time-dependent storage of the measurement data and means for data transmission from the measuring probes to the recording apparatus for use in the diagnosis of motility disorders influenced by the autonomic nervous system and the use of this system in the differential diagnosis of motility disorders.

A system and method for monitoring a patient's compliance with a medication regimen includes an electronic tag integral with or attached to a medicine delivery device such as a capsule, the tag having an antenna and a receiver/transmitter, the system also including a reader positioned externally for detecting the presence and location of the delivery device in the patient.

A method may include positioning a catheter, including at least one electrode, within an esophagus such that the electrode is proximate to at least one sympathetic ganglion. The methods may further include recruiting the sympathetic ganglion via an electrical signal, monitoring the recruitment of the sympathetic ganglion, and, based on the monitoring the recruitment of the sympathetic ganglion, adjusting the electrical signal from the at least one electrode.

A method of preventing or suppressing a false alarm during administration of food or medicine to a human or animal through a feeding tube having one or more sensors that generate a signal, comprises analyzing the signals to determine whether food or medicine is being administered and, if it is determined that food or medicine is present, preventing or suppressing an alarm. In a further step, the time and length of administration of food or medicine is recorded. When the feeding tube has at least two temperature sensors, differences in the temperatures recorded for the different temperature sensors indicate that food or medicine was administered. In a case where there is only one temperature sensor, the rate and extent of any temperature change of temperatures recorded from that temperature sensor are compared to an algorithm to determine whether feeding occurred. If the feeding tube has two or more electrodes that sense a change in impedance (galvanic or non-galvanic), that change indicates whether food or medicine is being administered. The signals are analyzed by a processor, monitor, or controller that generates an alarm signal.
