Abstract

A cooling radiofrequency ablation probe for delivering electrical and thermal energy to tissue of a patient's body is provided. The probe comprises a handle having an upper portion, a lower portion, and a Luer connector. The probe further comprises an extended electrocap assembly interfacing with one end of the handle, and a cable-tubing assembly interfacing with another end of the handle. The cable-tubing assembly includes an electrical cable that terminates at an electrical connector and a dual-lumen fluid tubing that terminates at inlet and outlet fluid connectors. An active tip of the extended electrocap assembly is configured to deliver the electrical and thermal energy to the tissue of the patient's body.
