Abstract
A medical probe kit and method of treating abnormal tissue within a patient is provided. The kit comprises a cannula having a shaft, a lumen extending through the cannula shaft, and a first ablation electrode disposed on the distal end of the cannula shaft. The cannula may have a handle mounted to the proximal end of the cannula shaft, and an optional fluid delivery port on the handle in fluid communication with the cannula lumen. The kit further comprises an ablation probe configured to be removably disposed within the delivery cannula lumen. The ablation probe has a shaft and a second ablation electrode disposed on a distal end of the probe shaft, wherein the first and second ablation electrodes are arranged in a bipolar configuration. Preferably, the ablation probe is slidable relative to the delivery cannula, whereby the distance between the first and second ablation electrodes can be adjusted. Thus, the delivery cannula can be used to interchangeably deliver the ablation probe and other medical elements, such as a biopsy needle, obturator, and chemotherapeutic agent.
