Medical devices for the treatment of sinus openings include handles, grooming sheaths, rails, guide wires, balloon catheter and balloon catheter movement mechanism. The handle has a proximal end, a distal end, and a longitudinal axis along the length of the handle. The grooming sheath has a distal end and a proximal end, wherein the proximal end of the grooming sheath is attached to the distal end of the handle. The rail has a distal end and a proximal end and is partially disposed within the grooming sheath to define an annular lumen between the rail and the grooming sheath. The guide wire operably extends from the distal end of the rail, and the balloon catheter is at least partially disposed within the handle and the annular lumen. The balloon catheter movement mechanism is operably disposed on the handle and configured to advance and retract the balloon catheter through both the handle and the annular lumen and along both the rail and the guide wire by user manipulation of the balloon catheter movement mechanism. . A method for treating a sinus opening includes the steps of partially inserting a medical device for the treatment of a sinus opening into the patient's anatomical structure, and then guiding a guide wire operably extending from the rail of the medical device into the patient's sinus opening. Positioning. The method further includes advancing the balloon catheter from the annular lumen of the medical device and along both the rail and the guide wire of the medical device. The method also includes treating the sinus opening through inflation of the balloon catheter. In this method, the annular lumen is between the rail of the medical device and the grooming sheath, and advancement is achieved through user manipulation of the balloon catheter movement mechanism of the medical device. |
