Abstract: A system can include an elongated member that includes a proximal portion and a distal portion that includes an agitator. The elongated member can extend through a working channel of an endoscope placed within a patient such that the agitator extends past a distal end of the endoscope into a target region within the patient. The agitator can include a plurality of disruption elements that can be in a low-profile state when within the working channel of the endoscope and can transition to an expanded state when advanced past the distal end of the endoscope. The plurality of disruption elements can define an empty cage configuration when in the expanded state. The system can include a driver coupled to the proximal portion of the elongated member. The driver can rotate the elongated member about a longitudinal axis of the elongated member.

Abstract: A system can include a tubular member to be inserted into an esophagus of a patient and a catheter assembly that includes a catheter tube that defines a length greater than a length of the tubular member and is configured to pass through a 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 defines a cutting element to core a blockage positioned in the esophagus of the patient. Advancement of the distal tip of the catheter tube into contact with the blockage can core a piece from the blockage that is passed through the catheter tube.

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.

Abstract: A system for clearing a blockage from a lumen of a patient, such as an impacted food bolus, can include a catheter that includes a distal end for insertion into the lumen of the patient. The catheter further includes a proximal end for coupling with a suction source at a position external to the patient. The catheter further includes a lumen extending through the proximal and distal ends. The system can include a cutting tip for cutting a morsel from the bolus as suction is applied to the bolus via the lumen of the catheter. The system can also include a positioning element that transitions from an undeployed state to a deployed state, which is expanded relative to the undeployed state. The positioning element can contact the esophagus to space the cutting tip from the esophagus when in the deployed state.
