Abstract
A method of directing energy to tissue using a fluid-cooled antenna assembly includes the initial step of providing an energy applicator. The energy applicator includes an antenna assembly and a hub providing at least one coolant connection to the energy applicator. The method also includes the steps of providing a coolant supply system including a fluid-flow path fluidly-coupled to the hub for providing fluid flow to the energy applicator, positioning the energy applicator in tissue for the delivery of energy to tissue when the antenna assembly is energized, and providing a thermal-feedback-controlled rate of fluid flow to the antenna assembly when energized using a feedback control system operably-coupled to a flow-control device disposed in fluid communication with the fluid-flow path.
