1. A lead extraction system comprising:

  • a guiding shaft having a shaft distal end, a shaft proximal end, and at least one lumen extending between the shaft distal end and the shaft proximal end;

    a handle attached to the shaft proximal end of the guiding shaft, wherein the handle has a cavity;

    a retractable inner catheter located inside the at least one lumen of the guiding shaft, wherein the retractable inner catheter has a distal end and a proximal end;

    an electrode means having a plurality of sheet members secured to the distal end of the retractable inner catheter, each of the plurality sheet members of the electrode means having a proximal end and a sharp-edge distal end, wherein the proximal ends of the plurality of sheet members are joined at the distal end of the retractable inner catheter, and wherein an electrical conductor is attached to the electrode means; and

    a deployment controller mounted on the handle and secured to the proximal end of the retractable inner catheter, the deployment controller having a deployed state for the retractable inner catheter to deploy outside of the shaft distal end of the guiding shaft, and the deployment controller having a non-deployed state for the retractable inner catheter to be retracted within the at least one lumen of the guiding shaft.
