Abstract
A system for clearing a blockage in a patient can include a tubular member that defines a channel and is insertable into an esophagus of the patient. The system can include a catheter assembly that includes a catheter tube defining a length greater than a length of the tubular member and being passable through the channel of the tubular member. The catheter tube can include a distal tip that defines a cutting element to core the blockage positioned in the esophagus. The catheter assembly can further include a catheter hub fixedly secured to the catheter tube and couplable with a vacuum line such that, when suction is provided via the vacuum line, advancement of the catheter tube into contact with the blockage cores a piece from the blockage that is passed through the catheter tube.
