Abstract
A method of cutting breast tissue for removal may include a step of providing a tissue cutting device having an elongate cutting element, the cutting element being movable between a bowed position and a retracted position, the cutting element having a radially outer side and a radially inner side. The tissue cutting device may be introduced into a breast and the elongate cutting element may be moved to the bowed position. A power source may be coupled to the elongate cutting element; and the cutting element may be rotated after the moving step so that the cutting element cuts the breast tissue. The radially outer side of the cutting element may have a larger surface area for transmitting energy to cut the tissue than the radially inner side.
