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.

Blockage clearing devices, systems, and methods

A device is configured to clear a bolus of food impacted within an esophagus, the device including a catheter tube having a hollow interior and a distal end configured to core the bolus of food and a proximal end configured to be coupled to a source of suction to clear the core.

Blockage removal

This invention provides a light delivery catheter having a proximal shaft with two lumens and a distal shaft connected to the proximal shaft, which distal shaft has only a single lumen. A guidewire and a light guide are received in the first and second lumens resectively, of the proximal shaft, either of which may be extended into the single lumen of the distal shaft, the distal shaft being sufficiently flexible to facilitate movement of the catheter through tortuous paths. A hub is provided having ports through which appropriate fluids may be applied to the lumens. When used to remove a blood clot in a blood vessel of the brain or other part of the body, the guidewire is extended through the single lumen in the distal shaft and is utilized to guide the catheter adjacent the clot, at least one guidewire/light guide exchange being performed to ablate the clot. Alternatively, the catheter may initially be passed through the clot to the distal side thereof and the catheter retracted through the clot as light energy and contrast fluid are applied therethrough.
