Abstract
A variety of electrical ablation apparatuses and methods are disclosed. In one embodiment, an ablation apparatus includes an injector catheter electrode having a proximal end configured to couple to an energy source and a fluid source. A distal end of the injector catheter defines an injection needle and defines an electrically conductive hollow channel for communicating a fluid from the fluid source to a treatment site. A balloon electrode is in fluid communication with a balloon catheter. The balloon catheter has a proximal end configured to couple to the energy source and the fluid source and a distal end configured to inflate the balloon electrode.
