1. A method of treating a nerve in a tissue region, the method comprising:
- positioning a working end of a device into the tissue region;
where the device includes a stimulation mode and an energy delivery mode, the stimulation mode comprises at least a first parameter setting that stimulates the nerve at a first distance from the working end, and a second parameter setting that stimulates the nerve at a second distance from the working end, where the first distance is greater than the second distance, and where the device is configured to prevent activation of the energy delivery mode when the stimulation mode is in the first parameter setting;
activating the device in the stimulation mode at the first parameter setting while observing for stimulation of the nerve;
repositioning the working end of the device in the tissue region to move the working end closer to the nerve;
re-activating the device in the stimulation mode at the second parameter setting while observing for stimulation of the nerve such that observing stimulation of the nerve using the second parameter setting confirms positioning of the working end of the device closer to the nerve; and
activating the device in the energy delivery mode to create a first treatment zone on the nerve, where activating the device in the energy delivery mode causes the device to reset to the first parameter setting.

Abstract
Methods and devices for improved precision in finding one or more nerves and then interrupting the transmission of neural signals through the target nerve. The treated nerve can be rendered incapable of transmitting neural signals for a select duration of time, where such a duration can be on a temporarily basis (e.g., hours, days or weeks) or a longer term/permanent basis (e.g., months or years). One embodiment of the apparatus includes a precise energy source system which features energy transfer elements that are capable of creating areas of nerve destruction, inhibition and ablation with precision.

18. A method of treating a nerve in a tissue region, the method comprising:
- positioning a device into the tissue region at a first location;
applying energy to the tissue region through the device at the first location using a first setting configured to stimulate the nerve within a first distance from a working end of the device;
observing for stimulation of the nerve;
re-applying energy to the tissue region through the device at a second location using a second setting configured to stimulate the nerve within a second distance from the working end of the device, where the second distance is less than the first distance;
re-assessing whether the nerve is stimulated at the second setting to determine if the second location is closer to the nerve than the first location;
activating the device to apply therapeutic energy to the nerve to affect the ability of the nerve to transmit a neural signal upon observing stimulation of the nerve when using the second setting. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

19. The method of 18, wherein the device resets to the first setting after applying energy to the nerve, the method further comprising re-adjusting the device to the second setting and subsequently re-applying energy to the tissue region through the device at a subsequent location using the second setting configured to stimulate the nerve within the second distance from the working end of the device.
