Abstract
An apparatus for use in a tissue ablation procedure includes a base, a fluid delivery tube coupled to the base, a first lever rotatably coupled to the base, the first lever having a first end biased to press against a portion of the fluid delivery tube to thereby close a lumen within the fluid delivery tube, and a second end, and a securing mechanism for securing the base relative to an ablation device. An ablation system includes an ablation device having an electrode, a fluid delivery tube coupled to the ablation device, and a control for simultaneously activating the electrode and opening the fluid delivery tube. A method of performing tissue ablation includes operating a control to activate an electrode, thereby delivering ablation energy to target tissue, wherein the step of operating the control also causes fluid to be delivered to the target tissue.
