Abstract: Ablation devices and associated methods are provided for use in ablating the margin of a cavity such as a surgical or body cavity. The ablation apparatus includes an integral or connected elongate probe and an elongate sleeve. Suction can be applied with a vacuum source operably connected to the proximal end region of the sleeve, whereby tissue of the surgical cavity is drawn against the surface of the sleeve. The probe includes one or more electrodes 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 surgical cavity.

Abstract: An ablation apparatus includes an introducer with a distal end sufficiently sharp to penetrate tissue. An energy delivery device is configured to be coupled to an energy source. The energy delivery device includes a first electrode and a second electrode each with a tissue piercing distal portion. The first and second electrodes are at least partially positionable in the introducer and deployable from the introducer at a selected tissue site to an expanded state. In the expanded state the deployed first and second electrodes distend laterally away from the introducer with a radius of curvature to form a shaped array of deployed electrodes at the tissue site when positioned at the selected tissue site. The first electrode distal portion and the second electrode distal portion are each at least partially made of a shaped memory alloy material that displays stress induced martensite behavior above body temperature. A cable couples the energy source to the energy delivery device.
