Abstract: A ratchet wrench includes a generally open head member and a handle connected thereto. A pair of generally C-shaped collars are hingeably connected to the head member for selectively closing and opening it and a locking tab is provided for selectively locking the collars in a position for closing the head member. A pair of semi-circular inserts are disposed within the collars and form a socket axially disposed within the head member and further form a peripheral ratchet wheel. A ratchet pawl engages the ratchet wheel for facilitating ratcheting rotation. The wrench may be adapted with an electrical drive for operating the ratchet wheel.

Abstract: A method and apparatus for delivering a small elongated flexible member into a body cavity. The apparatus includes a storage chamber opened at both ends for containing substantially the entire length of the member to be delivered with one end extending through the opening at the forward end of the chamber and the other end extending through the opening at the rear end of the chamber. A first valve is attached to the rear end of the chamber and has a passageway therethrough in communication with the interior of the chamber so that extension of the other end of the member through the valve and closing of the valve will retain the other end of the member in fixed position. A fluid port is positioned between this valve and the chamber and has a passageway in communication with the interior of the chamber. A second fluid port is attached to the forward end of the chamber in position on a nozzle and has a passageway therethrough in communication with the interior of the chamber.
