ABSTRACT:
A bifurcated balloon catheter for use in dilation of blood vessels includes separate catheter shaft and distal end portions interconnected in a movable manner. The catheter shaft and distal end portion each include guidewire and inflation lumens extending therethrough which the moveable distal end portion includes a perfusion lumen which is exposed to blood flow when the catheter is rotated or twisted a blood vessel so that the distal end portion is displaced relative to the catheter shaft. A tube interconnects the catheter shaft and the distal end portion and provides an axis of rotation for the distal end portion.
