Claim:
1. A device for cutting breast tissue for removal, the device comprising: a shaft, comprising a trough including a ledge portion; an elongate cutting element coupled with the shaft for cutting the breast tissue and movable between a bowed position, in which the cutting element extends at least partially out of the trough of the shaft, and a retracted position, in which the cutting element is retracted into the trough, wherein the cutting element has a radially outer side and a radially inner side, and wherein the radially outer side has a larger surface area for transmitting energy to cut the tissue than the radially inner side; an actuator coupled with the cutting element to slidably move the cutting element between the bowed position and the retracted position; and a flexible membrane attached to the cutting element and the shaft for collecting the cut breast tissue, wherein the flexible membrane is attached such that an opening in the flexible membrane opens automatically when the cutting element is moved from the retracted position to the bowed position, and wherein the flexible membrane retracts at least partially into the trough and the ledge portion of the shaft when the cutting element is in the retracted position.
