Abstract
A catheter for subintimally bypassing an occlusion in a vessel includes a catheter shaft including a guidewire lumen disposed therethrough and having a shaft longitudinal axis, at least two balloons coupled to an exterior of the catheter shaft such that longitudinal axes of the balloons are in a common plane with the shaft longitudinal axis when uninflated and with no external forces on the catheter. The balloons are configured such that when the catheter is disposed in the subintima of a vessel and the balloons are inflated, a tip of the catheter shaft is oriented towards a true lumen of the vessel distal of the occlusion.
