ABSTRACT:
A catheter for preventing the stenosis or restenosis of a body vessel or cavity, e.g., a blood vessel, whereby a membrane may be applied to the inner surface of the vessel or cavity. The inventive catheter tip utilizes (a) two inflatable chamber balloons which, when inflated, isolate a portion of the vessel or cavity for treatment and (b) an inflatable treatment balloon disposed between the two chamber balloons which provides a means for treating the isolated site. The invention permits the flow of body fluid, e.g., blood, to the distal side of the catheter tip while the balloons are in an inflated state. The invention further permits the rinsing and flushing of fluids or medications of an isolated longitudinal portion of the vessel or cavity prior to and after an application of a membrane located on the treatment balloon. The invention is useful for the prevention of restenosis of a blood vessel after PTA, PTCA or atherectomy or like procedures, or more generally for the treatment of any cavity requiring a membrane, film or coating.
