ABSTRACT:
A dilatation steerable guidewire for use in the vascular system having an inflatable balloon at the distal end and a bi-directional fluid pressure actuated ball valve forward of the balloon position. The guidewire construction provides torque and direction for manipulating the guidewire through the anatomy while the valve regulates fluid emission from the tip of the guidewire for visualization or into the balloon for inflation and deflation and is originated by fluid pressure.
