A dual function catheter handle is provided for simultaneous movement of two control wires. The catheter handle has a handle housing having proximal and distal ends and a generally hollow interior. A core is mounted in the interior of the handle housing, the core having a longitudinal slot therethrough. A first moveable member is provided with a proximal end mounted in the interior of the handle housing and a distal end extending outside the handle housing. The first moveable member is longitudinally moveable relative to the handle housing. A second moveable member is mounted in the longitudinal slot of the core and is longitudinally moveable relative to the core and handle housing. The second moveable member has a threaded surface. A rotatable member is mounted on the handle housing. The rotatable member has a threaded inner surface that mates with the threaded surface of the second moveable member so that rotation of the rotatable member causes longitudinal movement of the second moveable member. The first moveable member and second moveable member are capable of simultaneously moving proximally relative to the handle housing. |
