Abstract
Medical devices and methods for making and using the same are disclosed. An example method may include a method for treating tissue near a body passageway using an apparatus including a catheter having a plurality of electrodes, a radio-frequency energy generator, and a controller coupling the energy generator to the plurality of electrodes and configured to selectively energize the electrodes. The method may include using the apparatus to subject the tissue near the body passageway to a plurality of energy treatment cycles. The treatment cycle may include determining desired voltages for at least a subset of the electrodes for maintaining a predetermined target temperature profile proximate the subset of electrodes, setting an output voltage of the energy generator to correspond to the desired voltage determined for one of the electrodes, and energizing at least some of the electrodes at the output voltage to deliver energy to the body passageway.
