Abstract
The present invention provides an energy delivery device for use with a medical treatment system for the more efficacious treatment of patients during laser surgery which limits the number of uses or prevents reuse of the energy delivery device after a certain threshold limit has been reached. The energy delivery device comprises a diffusing optical fiber and a memory device having data programmed therein and being operatively connected to an energy generator the optical fiber includes a temperature sensor for generating a temperature signal in a closed loop manner. The data stored in the memory device includes a multiplicity of use parameters, usage limits, usage counts, and count limits all relating to the properties of the medical treatment system. The use parameters may include an elapsed time, a total treatment time, and a number of treatment sites. A main processor is also included for calculating a temperature from the temperature signal and for updating the use parameters in response to data received by the main processor. The main processor is also used to compare the use parameters to their corresponding usage limits. The main processor can create and increment a usage count when at least one of the use parameters exceeds its corresponding usage limit. Thereafter, the main processor compares the usage count to the count limit and disables the energy delivery device when the usage count exceeds a predetermined count limit.
