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.

         21 . A system for removing material from a lumen or a duct, comprising:
 a guide wire;   a flexible tube sized to be disposed through a flexible endoscope or a percutaneous access port;   a cutting tool coupled with a distal end of the flexible tube, the cutting tool configured to remove the material; and   a locking mechanism to couple the guide wire with the cutting tool to rotate the cutting tool using torque provided to the guide wire by a motor.   
     
     
         22 . The system of  claim 21 , further comprising at least one sensor coupled with the guide wire, the at least one sensor to provide data for navigating the guide wire through the lumen or duct. 
     
     
         23 . The system of  claim 21 , wherein the cutting assembly comprises an aspiration channel configured to retrieve the material removed from the lumen or duct. 
     
     
         24 . The system of  claim 23 , further comprising an irrigation channel configured to provide an irrigation substance to the lumen or duct, wherein the aspiration channel and the irrigation channel are connected to a pump device coupled to the proximal tube end of the cutting assembly. 
     
     
         25 . The system of  claim 21 , wherein:
 the cutting tool is further configured to maneuver from a first position at which the locking mechanism is adjacent to a proximal end of the guide wire to a second position at which the locking mechanism is adjacent to the distal end of the guide wire;   the locking mechanism is configured to couple with the guide wire positioned at the second position adjacent to the distal wire end of the guide wire; and   the cutting tool is configured to remove the material in response to the locking mechanism coupled with the coupling assembly and receiving the torque provided by the motor.   
     
     
         26 . The system of  claim 21 , wherein the guide wire comprises at least one of metal, steel, plastic, titanium, nickel, or carbon fiber. 
     
     
         27 . The system of  claim 21 , wherein the guide wire is radio opaque. 
     
     
         28 . The system of  claim 21 , wherein the guide wire comprises a flexible coil, a navigation wire, a motorized wire, or a braid. 
     
     
         29 . The system of  claim 21 , wherein a length of the guide wire is between 10 centimeters (cm) and 1000 cm. 
     
     
         30 . The system of  claim 21 , wherein the cutting tool is made of at least one of a metal or a plastic. 
     
     
         31 . The system of  claim 21 , wherein a length of the cutting tool is between 1 cm and 100 cm. 
     
     
         32 . A method, comprising:
 inserting a guide wire into a lumen or duct;   moving a flexible tube to a location of the material using the guide wire;   coupling a cutting tool with the guide wire using a locking mechanism; and   removing, by the cutting tool in response to the guide wire receiving torque provided by a motor coupled with the guide wire, the material from the lumen or duct.   
     
     
         33 . The method of  claim 32 , further comprising identifying the location of the material using an imaging technique. 
     
     
         34 . The method of  claim 33 , further comprising navigating the guide wire to the location of the material using the identified location. 
     
     
         35 . The method of  claim 33 , wherein the imaging technique comprises at least one of an ultrasound, fluoroscopic, or electromagnetic imaging technique. 
     
     
         36 . The method of  claim 32 , further comprising retrieving, through the cutting tool, the material removed from the lumen or duct. 
     
     
         37 . The method of  claim 32 , further comprising:
 determining the location of the material using at least one of x-ray, ultrasound, magnetic resonance imaging (“MRI”), or computer tomography (“CT”).   
     
     
         38 . The method of  claim 32 , further comprising providing, by at least one sensor coupled with the guide wire, data for navigating the guide wire through the lumen or duct. 
     
     
         39 . The method of  claim 32 , wherein the guide wire is radio opaque. 
     
     
         40 . The method of  claim 32 , wherein the cutting tool is made of at least one of a metal or a plastic.
