Abstract
A device for localizing a target tissue mass in a body includes a tubular trocar portion having a distal end and a proximal end portion that is removably attachable to a handle portion. The trocar portion contains at least a first plurality of locator wires that are movable between a retracted position within the trocar and a deployed position extending radially from the trocar. The first plurality of locator wires mounted for axial movement within the trocar portion between a proximal retracted position and a deployed distal position. The second plurality of locator wires is mounted for movement between a distal retracted position and a proximal deployed position. The locator wires are electrically energized to facilitate their deployment electrosurgically.
