Systems and methods for surgical procedures using torque driven guide wire

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 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.
