摘要：
Described herein are devices, systems and methods for determining if a nerve is nearby a device or a region of a device. In general, a device for determining if a nerve is nearby a device includes an elongate body having an outer surface with one or more bipole pairs arranged on the outer surface. Bipole pairs may also be referred to as tight bipoles. The bipole pairs may be arranged as a bipole network, and may include a cathode and an anode that are spaced relatively close together to form a limited broadcast field. In general, the broadcast filed is a controlled or “tight” broadcast field that extends from the bipole pair(s). Methods of using these devices and system are also described.
