摘要：
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.
