Patent ID: 7625385

Claim:
A medical apparatus for selectively deploying one or more sequentially positioned medical appliances at a target site, the apparatus comprising: a shaft having an outside surface, a proximal end, a distal end, and a channel having an opening; a handle slidably coupled to the outside surface of the shaft and moveable between the proximal and distal ends; at least one first stop located along the outside surface of the shaft to preclude movement of the handle along the shaft; and a string extending through the opening having one end in physical communication with the one or more sequentially positioned medical appliances and the other end in physical communication with the handle, wherein movement of the handle moves the string so that the at least one or more sequentially positioned medical appliances deploy from the apparatus; and wherein the at least one first stop is moveable from a first position in which said at least one first stop protrudes upwardly from the shaft to preclude proximal movement of the handle along the shaft to a second position in which said at least one first stop is depressed to allow the handle to be moved proximally along the shaft and over said at least one first stop.
