Claim 4:
5. A delivery apparatus for implanting a medical device in a patient's body, the delivery apparatus comprising:
a handle;
a plurality of elongate elements extending from the handle;
an actuation knob configured to actuate at least one of the plurality of elongate elements;
a toggle configured to toggle the actuation knob between a first state and a second state, wherein when the actuation knob is in the first state, rotation of the actuation knob moves at least two of the plurality of elongate elements axially, and wherein when the actuation knob is in the second state, rotation of the actuation knob moves only one of the plurality of elongate elements axially;
a rotatable component disposed in the handle, wherein the rotatable component is operatively coupled to a selected one of the plurality of elongate elements, such that when the actuation knob is in the first state, rotation of the actuation knob causes corresponding rotation of the rotatable component, the rotation of the rotatable component causing axial movement of the selected one of the plurality of elongate elements; and
one or more plungers disposed between the toggle and the actuation knob, wherein the toggle is configured to move the plungers between a first plunger position and a second plunger position upon movement of the toggle toward and away from the actuation knob, wherein:
when the plungers are in the first plunger position, the plungers extend through the actuation knob and into the rotatable component such that rotation of the actuation knob causes rotation of the rotatable component, and
when the plungers are in the second position, the plungers are withdrawn from the rotatable component such that rotation of the actuation knob does not cause corresponding rotation of the rotatable component.
