摘要：
Flow within a blood vessel or other body lumen may become constricted orultimatelyinterrupted. An apparatus is provided to perform various functions, such asinfusing fluid intoa body lumen and/or removing thrombus, objects, and/or obstructive materialfrom within abody lumen. The apparatus includes a shaft including a proximal end, distalend, lumenextending therebetween, and a balloon on the distal end having an interiorcommunicating withthe lumen. The apparatus includes a valve on the distal end that selectivelyopens or closes anoutlet communicating with the lumen. With the valve open, fluid introducedinto the lumenexits the outlet. With the valve closed, fluid introduced into the lumenexpands the balloon. Theapparatus also includes an actuator for axially compressing the balloon. Ahelical memberextends between ends of the balloon interior that expands the balloon from acontractedcondition to an expanded helical shape.
