Patent ID: 6866669

Claim:
A medical device delivery system for therapeutically treating a patient, comprising: an inner shaft, having proximal and distal ends; a tubular outer sheath, at least a portion of which surrounds a portion of the inner shaft member; a medical device within the outer sheath in an initial configuration; a handle operatively coupled with the inner shaft and the outer sheath; the handle having a first and second independently moveable actuator for adjusting the relative positions of the inner shaft and the outer sheath, each of the first and second actuators providing a different amount of mechanical advantage between an input to one of the first and second actuators by a physician and a resulting relative position of the inner shaft and the outer sheath respectively; and a locking member that releasably holds the outer sheath relative to the inner shaft in an initial configuration, thereby holding the outer sheath in the initial configuration and tending to resist inadvertently uncovering the medical device; and a unified actuator knob, wherein the first actuator is a slider coupled to the outer shaft adapted to slide with respect to the handle, wherein the second actuator is a threaded coupling between the knob and the slider; such that the unified actuator knob is adapted to operate both the first and second actuators.
