Abstract
Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a medical device for modulating nerves. The medical device may include an elongate shaft having a distal region. Two or more electrodes may be positioned adjacent to the distal end region of the elongate shaft. A control unit may supply power and control algorithms to the electrodes. The control algorithm may allow the electrodes to be operated simultaneously and individually.

- two or more electrodes positioned adjacent to the distal end region of the elongate member;
- a ground pad;
- a control unit in electrical communication with each of the two or more electrodes, the control unit positioned adjacent to the proximal end of the elongate shaft;
- an electrical conductor extending between each electrode and the control unit, each electrical conductor comprising an electrical switch and a current sensing circuit;
- wherein the control unit includes a control algorithm configured to selectively control power applied to the two or more electrodes.
A method for performing nerve modulation, the method comprising:
- providing a nerve modulation system, the nerve modulation system comprising:
- an elongate member having a proximal end and a distal end region;
- two or more electrodes positioned adjacent to the distal end region of the elongate shaft;
- a ground pad;
- and
- a control unit positioned adjacent to the proximal end of the elongate member;
- advancing the nerve modulation system through a lumen such that the two or more electrodes are adjacent to a target region;
- applying power to the two or more electrodes;
- measuring a temperature adjacent to each of the two or more electrodes;
- and
- monitoring an impedance between each of the two or more electrodes and the ground pad;
- wherein the control unit includes a control algorithm for controlling a power level and a duration power is applied to each of the two or more electrodes.
