ABSTRACT:
A dilation steerable guidewire for use in the vascular system having an inflatable balloon at the distal end and a bi-directional fluid and/or mechanical pressure operated valve forward of the balloon position. The guidewire construction provides torque and improved flexibility 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. One embodiment provides connection to the distal end via a spring element under the balloon to provide enhanced flexibility.
