Publication NumberUS 10321867Filing StatusIssued PatentAvailabilityUnknownFiling Date2017-02-06Publication Date2019-06-18
A method of detecting and measuring the condition of intraluminal esophageal mucosa. An esophagus is intubated with a catheter including an inflatable and deflatable balloon and one or more impedance sensing electrodes on an exterior surface of the catheter. The balloon is inflated to press the impedance sensing electrode(s) into a mucosa of the interior esophageal wall. An electric current is directed through the mucosa via the impedance sensing electrode(s) while the impedance sensing elect…

A mucosal impedance measuring system that is capable of direct and accurate impedance measurements of esophageal mucosa includes example multi-channel intraluminal impedance catheters with inflatable and deflatable components for positioning the impedance sensor electrodes in direct contact with the esophageal mucosa on the inside surface of the esophagus. Impedance measurements from multiple locations in the esophagus are processed for indications of mucosal damage that are indicative of dam…

Tools, methods and apparatus are provided that may be used to identify ineffective swallowing in the subject, including ineffective swallowing due to an obstruction, and may further be used to determine risk of aspiration in the subject. In one aspect, a method includes accessing intraluminal impedance measurements and pressure measurements obtained from the pharynx and/or esophagus of a subject during clearance of a bolus from the mouth and/or throat of the subject. The method further includ…

A system and method for automatically analyzing impedance and pH data from an esophageal probe includes a data collection system that collects and stores the output from the sensors for a certain period of time to locate reflux episodes in the waveforms. The data analysis system uses wavelet analysis to assist in locating bolus entry and exit points in the waveforms and to smooth waveforms for additional analysis. It also distinguishes between candidate acid reflux episodes and candidate non-…

A swallow challenge medium is thixotropic for easy swallowing and to provide enough viscosity for effective challenge to peristalsis and has high ionic density for effective impedance measurements by contact with electrodes positioned in a person's esophagus or oropharynx during swallow testing. The medium also has a high surface tension so as not to adhere to or coat the electrodes or probe surfaces. These physical characteristics are stabilized and consistent enough to provide standard for …
