摘要:
A system for clearing a blockage in a patient can include a tubular member that defines a channel, the tubular member being insertable into an esophagus of the patient. The system can further include a catheter assembly that includes a catheter tube, which defines a length greater than a length of the tubular member and is passable through the channel of the tubular member while the tubular member is positioned in the esophagus of the patient. The catheter tube can include a distal tip that defines a cutting element to core the blockage positioned in the esophagus of the patient. The catheter assembly can further include a proximal end coupled with the catheter tube, the proximal end being 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 from the blockage a piece of the blockage that is passed through the catheter.
