    摘要: A guiding catheter comprises an outer guide having a guide lumen and an annular balloon mounted to a distal end of the outer guide, and an inner guide movably disposed within the guide lumen of the outer guide, the inner guide comprising a fluted balloon mounted to a distal end of the inner guide. A method involves selectably pressurizing and depressurizing the annular balloon to control occlusion of fluid flow relative to the annular balloon, and selectably pressurizing and depressurizing the fluted balloon independently of pressurizing and depressurizing the annular balloon to permit perfusion of fluid flow relative to the fluted balloon and control anchoring of the fluted balloon within a generally tubular structure.
