1. A method of treating an occlusion of a blood vessel, comprising:
advancing an intravascular device within a lumen of the blood vessel to a position adjacent the occlusion, wherein the intravascular device comprises:
an elongate shaft defining a central longitudinal axis;
a first lumen extending to a distal opening at a distal end of the elongate shaft;
a second lumen extending to a distal opening located proximal of the distal end of the elongate shaft; and
an inflatable balloon secured to the elongate shaft, the inflatable balloon including an expandable portion;
inflating the inflatable balloon to orient the distal opening of the second lumen toward an intimal layer of a wall of the blood vessel; and
thereafter, advancing a subintimal device through the second lumen and into a subintimal space of the blood vessel proximal of the distal end of the elongate shaft.
