1. A device for dilating a sinus cavity lumen, comprising:

  • a guide tube, having a proximal end and a distal end, the distal end terminating in a distal tip, a distal portion of the guide tube being malleable;

    a sleeve member annularly positioned over the guide tube, wherein the sleeve member is movable relative to the guide tube and is capable of being advanced over the guide tube and past the distal tip;

    a balloon coupled to the sleeve member, wherein the balloon is extendable and inflatable at or beyond the distal tip of the guide tube;

    a guidewire extending through the guide tube and terminating at a point distal with respect to the guide tube, wherein the sleeve member comprises a distal sleeve portion having a diameter smaller than a proximal sleeve portion yet slightly larger than an outer diameter of the guidewire; and

    a handle disposed along a proximal portion of the guide tube, the handle comprising a knob moveable in a distal direction relative to the handle and operatively coupled to the sleeve member, wherein distal advancement of the knob advances the sleeve member and balloon over the guide tube in a distal direction.
