Claim Text:
1. A recanalization catheter for facilitating re-entry into a lumen of a blood vessel from a subintimal space, comprising: an elongate shaft extending distally from a hub assembly, the elongate shaft including a guidewire lumen; first and second mechanically actuatable wings positioned at a distal region of the elongate shaft, the first and second mechanically actuatable wings being actuatable between a retracted position and an expanded position with an actuation mechanism extending through the elongate shaft to the hub assembly; the distal region of the elongate shaft including first and second elongate channels opening out to an exterior of the elongate shaft; wherein in the retracted position the first and second mechanically actuatable wings are positioned in the first and second elongate channels, respectively, and in the expanded position the first and second mechanically actuatable wings extend outward from the first and second elongate channels, respectively wherein in the expanded position, the first mechanically actuatable wing curves away from a first plane, the first plane extending through and parallel to a central longitudinal axis of the elongate shaft and through the first elongate channel, and the second mechanically actuatable wing curves away from a second plane, the second plane extending through and parallel to the central longitudinal axis and through the second elongate channel.
