The invention is directed to a multifunctional catheter handle. The handle comprises a handle body and a core mounted within the handle body. A piston is provided having a distal end mounted in the handle body and a proximal end extending outside the handle body, to which a catheter body can be attached. The piston is longitudinally moveable relative to the core and handle body. A first puller wire anchor is fixedly mounted to the core. A cam receiver is mounted in the handle body so that the cam receiver is longitudinally slidable relative to the piston and core. A second puller wire anchor is fixedly mounted to the cam receiver. A generally cylindrical cam is mounted distal to the cam receiver in surrounding relation to the piston and core. Rotation of the cam relative to the piston and core causes longitudinal movement of the cam receiver and second puller wire anchor.
