ABSTRACT:
An apparatus and method for guiding and centering a catheter to a treatment site within a passageway in the human body includes a flexible tube having a distal end dimension to pass freely along the passageway, and a proximal end adapted to extend outside the body. The flexible tube is provided with a peripherally expandable zone at the distal end of the tube and a longitudinal lumen through the flexible tube dimension for passing a catheter therethrough. The distal end of the flexible tube is guided to a desired location within the passageway. The peripheral zone at the distal end of the tube is then expanded so that the expandable zone pushes against the inner wall of the passageway to center the distal end of the tube within the passageway. With the tube positioned within the passageway, a catheter is passed through the longitudinal lumen of the flexible tube.
