  • Patent number: 10179225
    Abstract: A guidewire introducable into a bodily lumen having an obstruction therein is provided. An introducer needle is advanced through tissue and into the bodily lumen. A guidewire is advanced through the introducer and into the lumen. The guidewire is advanced further through the lumen until an atraumatic distal tip of the guidewire encounters an obstruction the distal tip cannot pass in a straight forward manner. The distal tip is pressed against the obstruction such that a flexible segment proximal of the distal tip forms a loop distal of the distal tip. The guidewire is advanced further through the lumen such that the loop of the flexible segment is pushed past the obstruction and the distal tip is pulled distally past the obstruction. A greater diameter guidewire extension can be coupled to the back end of the guidewire, providing function as a larger diameter guidewire.

  • Patent number: 10143416
    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.
