1. An orienting catheter for facilitating reentry into a lumen of a vessel having an occlusion therein from a subintimal space in a wall of the vessel, the orienting catheter comprising:
a catheter shaft extending distally from a hub, the catheter shaft defining a guidewire lumen extending therethrough;
first and second inflatable balloon members disposed on a distal end region of the catheter shaft, the catheter shaft including an inflation lumen in fluid communication with the first and second inflatable balloon members;
a first aperture in communication with the guidewire lumen, the first aperture opening to an exterior of the catheter shaft between the first and second inflatable balloon members on a first side of the catheter shaft; and
a second aperture in communication with the guidewire lumen, the second aperture opening to an exterior of the catheter shaft between the first and second inflatable balloon members on a second side of the catheter shaft, the first side of the catheter shaft being opposite the second side of the catheter shaft;
wherein the first and second inflatable balloon members are configured to cooperate with the wall of the vessel to self-orient the distal end region of the catheter shaft within the subintimal space such that the first aperture or the second aperture opens toward the lumen of the vessel.
