Abstract
Systems and methods are disclosed for the treatment of a target tissue by directionally delivering energy and/or bioactive materials to achieve a therapeutic effect. A balloon catheter system having a balloon portion and a plurality of electrodes may be energized to selectively deliver energy, bioactive materials, or a combination thereof to target tissue including tissues disposed about a lumen. The tissue may be targeted by applying energy, making tissue impedance analysis, and further selectively energizing electrodes through the use of an energy source with a controller.
