Abstract
A catheter for facilitating re-entry of a re-entry wire into a true lumen or into any desired region of a blood vessel may have an elongate shaft with a first lumen. A distal port and a first proximal port are fluidly coupled with the first lumen. A wire re-entry port is adjacent the distal end of the elongate shaft. The wire re-entry port has a re-entry axis. An ultrasound transducer on the catheter is configured to produce an image the blood vessel, and has a central axis that allows visualization of the re-entry wire as it exits the re-entry port and re-enters the true lumen. This allows the operator to ensure that the re-entry wire re-enters the true lumen in a desired location and does not damage the vessel.
