Abstract
Ablation devices and associated methods are provided for use in ablating a target tissue, such as a cystic lesion. The ablation apparatus includes an integral or connected elongate probe and a deployable structure that is axially slidable along the outer surface of the electrode. The electrode can be disposed at the probe's distal end region for ablating tissue when the electrode(s) are activated to create an ablated margin of tissue at least partially surrounding the target tissue. Suction can be applied with a vacuum source operably connected to the proximal end region of the deployable structure. A target tissue, such as a cystic lesion, can be drawn against the surface of the electrical probe.
