Abstract
An iontophoresis drug delivery system and method for denervation of the renal sympathetic nerve and iontophoresis drug delivery. The system includes an iontophoresis catheter fitted with a drug coated balloon. The iontophoresis catheter includes a balloon near its distal tip or end that contacts the vessel wall circumferentially when inflated. One or more electrodes are associated with a surface of the balloon, and may be disposed on an outer surface of the balloon. The electrodes are operably coupled to an energy source configured to produce a bipolar or monopolar electric field between two balloon electrodes and/or between one balloon electrode and another electrode placed in contact with a part of the patient's body. During use, the disclosed drug-delivery catheter produces an electric potential gradient within adjacent tissue, that, in turn, facilitates iontophoresis delivery of a drug. The disclosed catheter can also include a store of one or more drugs to be delivered to the targeted tissue.
