Tissue specimen isolating and damaging device and method

Abstract

A device and method for treatment of a tissue specimen disposed in surrounding tissue has a tissue specimen isolating toot and a tissue specimen damager. The tissue specimen isolating tool isolates the tissue specimen from the surrounding tissue. The tissue specimen damager damages the tissue, with a possible end result being necrosis. The severing tool may have a cutting member that is extendable to an outwardly radially bowed position about device. The tissue specimen is isolated by rotating the cutting member about the tissue specimen. The cutting member may be functionally connected to a cutting member radio frequency generation source. The tissue specimen damager may damage the tissue specimen using ionizing radiation, cutting devices, thermal treatment devices, chemical treatment devices, or sealing an outer boundary of the tissue specimen.
