1. A catheter for use in analyzing neural activity of nerves that surround a biological lumen, the catheter comprising:
a handle including first, second, and third actuators; and
a shaft extending from the handle and including proximal and distal electrodes that are selectively deployable;
the first actuator configured to selectively deploy the proximal electrode in response to the first actuator being manually maneuvered;
the second actuator configured to selectively deploy the distal electrode in response to the second actuator being manually maneuvered; and
the third actuator configured to selectively adjust a longitudinal distance between the proximal and distal electrodes in response to the third actuator being manually maneuvered; wherein: the shaft also includes a plurality of nested and concentric tubes; one of the tubes is mechanically coupled between the first actuator and the proximal electrode that is selectively deployable such that the one of the tubes and the first actuator are collectively configured to deploy the proximal electrode in response to the first actuator being manually maneuvered; another one of the tubes is mechanically coupled between the second actuator and the distal electrode that is selectively deployable such that the another one of the tubes and the second actuator are collectively configured to deploy the distal electrode in response to the second actuator being manually maneuvered; and a further one of the tubes is mechanically coupled to the third actuator such that the further one of the tubes and the third actuator are collectively configured to adjust a longitudinal distance between the proximal and distal electrodes, while one of the proximal and distal electrodes is deployed, in response to the third actuator being manually maneuvered.
