Abstract: Systems and methods for removing a material from a lumen or duct include a guide wire to navigate to the material and a cutting assembly that can then be guided along the guide wire to reach the material. A proximal wire end can be connected to a pump device configured to provide an irrigation substance along a delivery channel of the guide wire and release the irrigation substance at a distal wire end. A power source can apply a current to the guide wire to magnetize a coupling assembly disposed on the guide wire. The cutting assembly can couple to the guide wire by engaging a locking mechanism of the cutting assembly with a coupling assembly of the guide wire.

The cutting assembly can couple to the guide wire by engaging a locking mechanism of the cutting assembly with a coupling assembly of the guide wire. The locking mechanism can receive torque provided by a motor coupled to the proximal wire end of the guide wire to rotate the cutting tool of the cutting assembly to remove the material.

Abstract: An endoscopic instrument (312, 820, 824) includes an outer tubing (206) extending from a proximal tubing end to a distal tubing end, a flexible torque component (200) extending through the outer tubing, an articulation assembly (400, 500, 600, 700, 828), and an end effector (450, 550, 650, 750, 824). The articulation assembly (400, 500, 600, 700, 828) is coupled to the distal tubing end and includes a plurality of segments (404, 408, 504, 604, 704) and at least one control member (412, 512, 612, 712) extending from a proximal control end to a distal control end coupled with the plurality of segments. The control member manipulates an orientation of at least one segment of the plurality of segments responsive to receiving a control input at the proximal control end.
