Abstract

The invention features a medical instrument for collecting multiple biopsy specimens including a long shaft having proximal and distal ends; a biopsy assembly located at the distal end of the long shaft defining an exposed biopsy space for receiving tissue to be severed and an enclosed storage space located proximally of the biopsy space and axially moveable with respect to the shaft for storing severed tissue; an actuator located at the proximal end of the shaft; and a force-transmitting member associated with the shaft, extending from the actuator to the biopsy assembly. Driving the actuator severs tissue which is located in the biopsy space and thereafter stored in the storage space. Multiple specimens may be taken sequentially and stored in the assembly.
