## Indications for use
The Model 90 Electrosurgical Probe is designed to supply energy (generated by the RITA Medical Systems’ electrosurgical generator) for use in electrosurgery and is designed for the following: Incorporation of multiple needles on each probe minimizing the number of invasive accesses necessary to achieve desired lesions. Provide a minimally invasive laparoscopic, percutaneous, or intraoperative access to the targeted tissue. Deliver radiofrequency energy in a controlled fashion to create coagulative necrotic lesions. Incorporate thermocouples for temperature feedback. Provide for local delivery of fluid.
