  • Patent number: 11406319
    Abstract: A method classifies vibrational data acquired for a swallowing event to identify a possible swallowing impairment in a candidate. The method includes receiving axis-specific vibrational data for an anterior-posterior (A-P) axis and a superior-inferior (S-I) axis and representative of the swallowing event, for example from a sensor operatively coupled to a processing module that is a local or remote computing device. A portion of the axis-specific vibrational data for the A-P axis can be combined with a portion of the axis-specific vibrational data for the S-I axis on the processing module using one or more of linear combination, squared (power) sum, moving window correlation of the two signals, local minimum or local maximum of the two signals, and trigonometric relation. The method can include outputting from the processing module a classification of the swallowing event based on the combined vibrational data.

  • Patent number: 11147502
    Abstract: A method for quantifying swallowing function can include subjecting swallowing segments and non-swallowing segments of vibrational data to processing selected from the group consisting of adaptive trimming, false positive reduction, and a combination thereof. Preferably the vibrational data represents swallowing activity, is from a sensor positioned on the throat of a patient, and is associated with at least one axis selected from the group consisting of an anterior-posterior axis and a superior-inferior axis. Preferably a processing module operatively connected to the sensor performs the processing of the swallowing segments and the non-swallowing segments of the vibrational data. A device comprising a processing module and a sensor such as a single-axis accelerometer or a dual axis accelerometer can perform one or more steps of the method.

  • Patent number: 8992446
    Abstract: Dual-axis swallowing accelerometry is an emerging tool for the assessment of dysphagia (swallowing difficulties). These signals however can be very noisy as a result of physiological and motion artifacts. A novel scheme for denoising those signals is proposed, i.e., a computationally efficient search for the optimal denoising threshold within a reduced wavelet subspace. To determine a viable subspace, the algorithm relies on the minimum value of the estimated upper bound for the reconstruction error. A numerical analysis of the proposed scheme using synthetic test signals demonstrated that the proposed scheme is computationally more efficient than minimum noiseless description length (MNDL) based de-noising. It also yields smaller reconstruction errors (i.e., higher signal-to-noise (SNR) ratio) than MNDL, SURE and Donoho denoising methods. When applied to dual-axis swallowing accelerometry signals, the proposed scheme improves the SNR values for dry, wet and wet chin tuck swallows.

  • Patent number: 8986230
    Abstract: An enteral tube includes a built-in Gastric Residual Volume (GRV) detection sensor at the distal end and a GRV indicating device at the proximal end for indicating the current GRV without requiring the aspiration of any stomach contents. The enteral tube with integrated GRV detection sensor is flexible and long enough to be looped around within the stomach. Weights may be employed to keep the sensor located generally at the lowest portion of the gastric cavity. The GRV detection sensor may include a sealed air column terminating with a flexible membrane. When the enteral tube and sealed air column are inserted into the stomach and submerged in gastric contents, pressure is exerted against the flexible membrane, and therefore against the sealed air column. A pressure sensor detects the pressure within the sealed air column and provides a signal or level representative of the amount of gastric contents in the stomach.

  • Patent number: 8968217
    Abstract: An apparatus for determining an optimal amount of tissue compression for applying a surgical element to tissue is disclosed. The apparatus includes a device for compressing tissue which supports a measuring device adapted to detect a tissue parameter upon the compression of tissue. The measuring device communicates with an indicator. Upon compressing tissue, when the measuring device determines that the compressed tissue parameter reaches a predetermined threshold, the measuring device sends a signal to the indicator such that the indicator provides an indication to a surgeon that the threshold has been reached. The measuring device may include a load cell and the tissue parameter may be a viscoelastic reactive force of the tissue per unit time.

  • Publication number: 20150038805
    Abstract: A method for characterization of a patient's esophagus may include receiving data measured by an impedance and high resolution manometry catheter in an esophagus in which the data may be representative of a pressure and/or an impedance associated with a swallowing event. The method may also include determining a cross-sectional area of the esophagus based on the received data and a pre-determined amount of a bolus consumed during the swallowing event. Systems and apparatus for characterizing a patient's esophagus may also include measuring data with a high resolution manometry catheter to determine the cross-sectional area, work, and compliance of the esophagus as a function of time during a swallowing event. Averaged data may establish a database of normal values for work done and compliance and allow for comparison of a patient to normal pathology.

  • Patent number: 8915867
    Abstract: A device and method for mapping, diagnosing and treating the intestinal tract is provided using a capsule passing through the intestinal tract. Further, a capsule tracking system is provided for tracking a capsule's location along the length of an intestinal tract as various treatment and/or sensing modalities are employed. In one variation, an acoustic signal is used to determine the location of the capsule. A map of sensed information may be derived from the pass of a capsule. Capsules may be subsequently passed through to treat the intestinal tract at a determined location along its length. One variation uses an electrical stimulation capsule to treat and/or diagnose a condition in the intestinal tract.

  • Patent number: 8827929
    Abstract: An apparatus for measuring distensibility of a vessel, lumen or sphincter includes a balloon catheter having a balloon located adjacent a distal end of a catheter for inserting in, for example, the sphincter, the distensibility of which is to be determined. The balloon is inflated to respective first and second pressures to distend the sphincter to respective first and second transverse cross-sectional areas which are measured. The first and second pressures are selected so that the relationship between the pressure and the cross-sectional area of the sphincter is linear. The distensibility of the sphincter is determined as a distensibility index, which is the value of c from the equation of a line y=mx+c containing the values of the first and second pressures and areas, where x represents pressure and y represents area.

  • Patent number: 8827934
    Abstract: A medical system provides navigation assistance to a surgeon for navigating a flexible medical device through linked passages of an anatomical structure to a target area. For tracking, navigation, and other purposes, information of extrema is determined during expansion and contraction cycles of an object by receiving time sampled information from sensors distributed along a length of a flexible device so as to indicate the shape of the device over time while the device extends through a lumen of the object so as to conform to and resemble the shape of the lumen, displacements over time of a selected point at a selected insertion length of the flexible device into the lumen of the object relative to a reference point are determined, extrema time points are determined by identifying sign changes of the slope of the determined displacements over time, and extrema types are determined using extrema type characteristics.
