1. A system comprising:
a catheter having a wall that defines an inner lumen of the catheter, the inner lumen extending between a proximal hub with an electrical current controller, and a distal tip;
a metallic region comprising at least two abutting metals in a coiled configuration positioned at the distal tip of the catheter,
wherein at least a portion of a first metal of the metallic region comprises an outer perimeter of a bimetallic coil and at least a portion of a second metal of the metallic region comprises an inner perimeter of the bimetallic coil; and
two conductive wires extending along a longitudinal axis of the catheter in electrical communication with the electrical current controller and in electrical communication with at least a portion of the metallic region.
