Claim Text:
1. A catheter for bypassing an occlusion via a subintimal approach, the catheter comprising: a catheter shaft including a guidewire lumen disposed therethrough, the catheter shaft having a shaft longitudinal axis; a first balloon coupled to an exterior of the catheter shaft, wherein a proximal portion of the first balloon is coupled to the catheter shaft at a first balloon proximal bond and a distal portion of the first balloon is coupled to the catheter shaft at a first balloon distal bond, wherein the first balloon is not coupled to the catheter shaft between the first balloon proximal bond and the first balloon distal bond, and wherein the catheter shaft is external to the first balloon between the first balloon proximal bond and the first balloon distal bond; and a second balloon coupled to an exterior of the catheter shaft opposite the first balloon relative to the catheter shaft, wherein a proximal portion of the second balloon is coupled to the catheter shaft at a second balloon proximal bond and a distal portion of the second balloon is coupled to the catheter shaft at a second balloon distal bond, wherein the second balloon is not coupled to the catheter shaft between the second balloon proximal bond and the second balloon distal bond, and wherein the catheter shaft is external to the second balloon between the second balloon proximal bond and the second balloon distal bond; wherein when the catheter is disposed in the subintima of a vessel and the first balloon and the second balloon are inflated, the catheter shaft bends such that a tip of the catheter shaft distal of the first and second balloons is oriented towards a true lumen of the vessel.
