Blockage clearing devices, systems, and methods

A system comprising:

• a tubular member that defines a channel and comprises a distal tip, the tubular member configured to be inserted into an esophagus of the patient;
• and
• a catheter assembly comprising:
• a catheter tube that defines a length greater than a length of the tubular member and is configured to pass through the channel of the tubular member such that a distal tip of the catheter tube extends distally past the distal tip of the tubular member while the tubular member is positioned in the esophagus of the patient, the distal tip of the catheter tube defining a cutting element configured to core a blockage positioned in the esophagus of the patient;
• and
• a catheter hub fixedly secured to a proximal end of the catheter tube, the catheter hub comprising a connector configured to couple with a vacuum line such that, when suction is provided via the vacuum line, advancement of the distal tip of the catheter tube into contact with the blockage cores a piece from the blockage that is passed through the catheter tube.
