Abstract: An apparatus and method for performing a medical procedure comprising an elongated member having an aperture extending longitudinally therethrough. The member has a proximal and an opposite distal end. An actuator is positioned within the aperture and has a proximal end and an opposite distal end. Biopsy means are connected to the distal end of the actuator for cutting and collecting biopsy specimens. Either the elongated member or the distal tip is modified to receive the cut specimens in the order of acquisition. After serial acquisition, the holding segment is separated from the remainder and closed by a cap to form a processing cassette. The cassette holds the specimens in the order of acquisition through fixation and processing to be opened for slicing or analysis.
