Abstract
An intravascular device to assist in the visualization of intravascular lumens and the navigation of guide members, the device including two elongate coaxial tubes which define a central lumen and an annular lumen. A manifold is coupled to the proximal end of the two tubes and includes a first port connected to the central lumen and a second port in fluid communication with the annular lumen. The central lumen and the annular lumen are fluidly independent at the proximal end and are open to the vasculature at the distal end. The coaxial tubes engage each other at the distal end to limit longitudinal movement therebetween.
