(57) SUMMARY An apparatus and method according to the present invention for treating a tissue sample disposed in a surrounding tissue includes a tissue sample isolation tool and a tissue sample damager. The tissue sample isolation tool isolates a tissue sample from surrounding tissue. On the other hand, the tissue sample damageer damages the tissue in a state where the final result can be necrosis. The severing tool may include a cutting member that is expandable to an outwardly bowed position about the device. The tissue sample is isolated by rotating the cutting member around the tissue sample. The cutting member may be operatively connected to a cutting member radio frequency source. The tissue sample damageer can damage the tissue sample using ionizing radiation, a cutting device, a thermal treatment device, a chemical treatment device, or sealing the outer boundary of the tissue sample. |
