Abstract
True lumen reentry devices and methods useable for redirecting a guidewire from a subintimal tract within a wall of a blood vessel into the true lumen of the blood vessel. A reentry catheter device comprises a main catheter shaft having at least one guidewire outlet aperture with at least one side tube located on a distal portion of the main catheter shaft. The side tube(s) is/are tracked over initially inserted guidewire(s) to advance a distal portion of the reentry catheter device into the subintimal tract with a guidewire.
