Abstract

An excisional biopsy method is disclosed. The method can include rotating an arcuate shaped electrode around a tissue specimen, and drawing a sheath around the tissue specimen as the specimen is cut from a tissue mass. In one embodiment, the method includes tunneling to a tissue site with one electrode, and cutting with a second electrode to obtain the tissue specimen.
