Abstract
Medical devices and methods are described that include catheter systems for use in vasculature. The catheter systems include a re-entry catheter for use with numerous guide wires to direct the guide wire from the extraluminal or subintimal space back into a true lumen after the guide wire has entered the subintimal space. An example of the re-entry catheter is a single lumen catheter configured to facilitate placement and positioning of guide wires and catheters within vasculature. An embodiment places and positions guide wires and catheters within peripheral vasculature. More specifically, the re-entry catheter provides for re-entry of a guide wire back into the true lumen of peripheral vasculature from a subintimal space.
