Abstract

A method of managing a system of minimally invasive surgery. The management method includes providing a practitioner with a minimally invasive surgery system including a controller. One or more use parameters is stored to memory associated with the controller. In addition, an electrosurgical probe having its own memory is provided to mate with the remaining elements of the system. Complementary use parameters are stored in the memory of the probe. The management method also includes communicating and comparing the use parameters of the controller with the complementary use parameters of the probe and managing the use of the electrosurgical probe according to the use parameters.
