Patent ID: 8818520

Claim:
A nerve stimulation system comprising: a neurostimulator unit including: a pulse generator for electrically coupling to a percutaneous needle electrode having a leading end for inserting adjacent a stimulation site of a patient and a transcutaneous electrode configured to be applied to skin adjacent the stimulation site of the patient, and a microcontroller in communication with the pulse generator for monitoring a number of available treatment credits and activating the pulse generator, each available treatment credit corresponding to a treatment session and the pulse generator operable to be activated for performing the treatment session when the number of available treatment credits is at least one, the pulse generator generating current pulses during the treatment session that pass between the transcutaneous electrode and the percutaneous needle electrode for providing stimulation to the stimulation site; and a computer system operable to communicate with the microcontroller of the neurostimulator unit, the computer system for receiving a treatment credit request having purchase information including a number of treatment credits purchased, each treatment credit purchased corresponding to an available treatment credit, and transmitting the number of treatment credits purchased to the microcontroller of the neurostimulator unit.
