    Abstract: In a method and an apparatus for determining the position of an esophageal catheter that is inserted into the esophagus of a patient, the catheter having a number of electrodes, muscular activity of the diaphragm is stimulated by applying a stimulus signal that produces a myoelectrical signal in the diaphragm having a well-defined peak at a specific point in time. The myoelectrical signal is detected by respective pairs of electrodes of said catheter, and the electrode pair or pairs that detected the signal having the highest amplitude at the specific point in time is identified. If this electrode pair or these electrode pairs that detected the signal with highest amplitude are not located approximately at the middle of the catheter, an indication is emitted that the position of the catheter should be adjusted.

    Abstract: 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. A second electrode is formed on the exterior surface of the endotracheal tube substantially above the first location. 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.

  • Publication number: 20100317956
    Abstract: A nerve monitoring device, including a cannula, a sensor for monitoring a nerve, and an optional support element, can be inserted into an anatomic space. The cannula, sensor and/or support element can automatically conform to and match the geometry of the anatomic space, which can enhance desired contact between the sensor and anatomic features, such as muscles, nerves or tissue in the space in an atraumatic manner. The sensor, cannula and/or support element can include one or more strips or other elements that convert from a retracted mode to an expanded mode in which the strips or elements expand, enlarge or otherwise move to match the geometry of the space and place the sensors in precise monitoring proximity relative to the target muscles, nerves or tissues. An exemplary application of the device is in the field of laryngeal monitoring, however, the device is well suited for other applications.

  • Publication number: 20100087715
    Abstract: The present invention is directed to a feeding tube in particular for total parental nutrition and/or medicine dosing. The feeding tube functionality is combined with internal monitoring of vital functions, such as ECG, PH, etc. The position of the electrodes is essential for measuring the optimal signal. In this invention the optimal position is determined by measuring the inversion point of the ECG signal. During insertion of the catheter or modified feeding tube the ECG signal is continuously monitored. Via an acoustic signal the strength of the signal is notable. This enables the nursing staff a simple control of the insertion process.

  • Publication number: 20100063376
    Abstract: The present invention provides a nerve monitoring device. The device includes a cannula, a sensor for monitoring the nerve and an alignment device. The cannula can be any surgical cannula, and is preferably an endotracheal tube. The sensor can be an electrode or other sensor that is capable of sensing nerve activity. The alignment device is a device that ensures that after insertion of the nerve sensor into a patient, the sensors are aligned to properly monitor the target nerve or muscle. The internal alignment device may communicate externally to surgeon by using electromagnetic energy as either a transmittor or a receiver. The mismatch of triangular laryngeal anatomy to circular cannula anatomy can be compensated for by a) altering the geometry (external shape) of the cannula and b) using soft, felt-like expandable electrodes. Rotational error can be compensated for by using a multi-electrode array wherein the optimized recording montage can be simply selected on the external recording device.

  • Patent number: 7277749
    Abstract: Many individuals generate excessively loud snoring during their sleep, often to the point where others cannot tolerate sleeping in the same room with them. Most cases of snoring are caused by excessive bulk and flaccidity of soft tissues of the palate and uvula that vibrate as air flows past them. These palate and uvula contain muscles whose contractions can stiffen and displace the soft tissues so that they do not vibrate. The invention provides electrical stimulation that causes the oropharyngeal muscles to contract during sleep using one or more microstimulators injected into or near these muscles or the nerves which innervate them. The invention also provides methods of determining the anatomical structures implicated in snoring and testing such locations for effective placement and stimulation of muscle contraction to decrease the frequency or magnitude of snoring.
