An inflation adaptor is provided to move a wire within a hollow tubular body, the movement of the wire enabling actuation of an expandable member at the distal end of the hollow tubular body. The expandable member can be a balloon, filter or similar device. The adaptor generally includes a clamping mechanism which clamps the hollow tubular body and wire within the adaptor, and also includes a drive mechanism for moving the wire within the hollow tubular body. An actuator, such as a rotatable knob, is provided to operate both the clamping mechanism and the drive mechanism. The adaptor may also include a fluid delivery and expansion system within a housing when the expandable member is a balloon, wherein movement of the actuator delivers a predetermined amount to the balloon while still operating the clamping mechanism and the drive mechanism. The adaptor may also include one or more magnets within the housing to prevent kinking of the wire and the hollow tubular body during loading of the hollow tubular body.
