Abstract:
A handle for loading and controlling relative axial movement of the first and second coaxial members of a medical device, the handle comprising:an outer elongated housing having a distal end, a passage extending longitudinally therealong and having external communication thereto, and an end cap with a boss and a coating at a proximal end of the end cap, and further comprising a first attachment mechanism for attaching the outer elongated housing of the first coaxial member when the proximal end of the medical device is in the passage for constraining the first coaxial member against axial movement relative to the outer elongated housing; an inner elongated member positioned in said passage and extending therealong supported for axial movement relative to the outer elongated housing, and an insert slotted to accommodate the boss, and further comprising a second attachment mechanism for attaching the inner elongate member to the second coaxial member when the proximal end of the medical device is in the passage for constraining the second coaxial member against axial movement relative to the inner elongated member; the outer housing and the inner member including a projection positionable in an associated channel arrangement to achieve relative rotational and longitudinal movement of the first and second device members; and a spring operably coupled between the outer elongated housing and the inner elongated member for biasing the outer elongated housing and the inner elongated member toward a particular relative longitudinal position.
