Rf bipolar steam generation ablation device

Abstract

Disclosed embodiments include apparatuses, systems, and methods for vaporizing a conductive fluid at or adjacent a reference point. In an illustrative embodiment, an apparatus includes a primary electrode extending to a first distal end positionable adjacent to a reference point and having a first proximal end selectively couplable with a first pole of a power source. The primary electrode defines a lumen therein and defines at least one opening to the lumen within a distal range adjacent the first distal end. A secondary electrode extends through the lumen of the primary electrode and has a second distal end extending into the distal range and a second proximal end selectively couplable with a second pole of the power source. The secondary electrode is electrically insulated from the primary electrode except within the distal range, where a conductive fluid is receivable within the distal range so as to be in electrical contact with the primary electrode and the secondary electrode. The conductive fluid is vaporizable at the distal range responsive to application of power across the first pole and the second pole of the power source and vaporized conductive fluid is expellable through the at least one opening.
