Abstract

An occlusion bypassing apparatus for re-entering the true lumen of a vessel after subintimally bypassing an occlusion in a vessel. The apparatus includes an outer shaft component, a needle component, and an inflatable balloon. The outer shaft component has a side port proximal to a distal end thereof and a needle lumen there-through that includes a curved distal portion that terminates at the side port of the outer shaft component. The needle component is configured to be slidably disposed within the needle lumen of the outer shaft component. The inflatable balloon includes a body portion that is disposed distal to the side port of the outer shaft component, and the body portion of the balloon has a flattened profile in an inflated state with first and second chambers that laterally extend from opposing sides of the outer shaft component for stabilizing the apparatus within a subintimal space.
