Abstract
Occlusion bypassing apparatuses are disclosed for re-entering the true lumen of a vessel after subintimally bypassing an occlusion in a vessel. The occlusion bypassing apparatuses include a shaft component and a needle component slidably disposed within the shaft component and having an angled configuration when deployed. In embodiments hereof, the needle component has an angled distal tip segment that may be utilized to selectively bend a flexible distal portion of the shaft component in order to extend the flexible distal portion towards the true lumen of the vessel. The needle component is distally advanced relative to the shaft component to pierce through the intima of the vessel and thereafter enter the true lumen.
