Appl. No.:

11/393623

International Classification:

A61M 5/178

US Classification:

604164010

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.

International Classification:

A61M005/178

US Classification:

604164010

Abstract:

Medical devices/methods are described that include catheter systems for crossing total occlusions in vasculature. The catheter systems are for use with numerous guide wires to direct the wires from the extraluminal or subintimal space back into a blood vessel lumen after the wire has entered the subintimal space. The catheter systems comprise a catheter body having at least one lumen configured to track over a wire. An endpiece that includes at least one port in communication with the lumen couples to the distal region of the catheter body. A working element is configured to deploy through the port for delivery from a location within the extraluminal space to locations within the vessel true lumen when advanced distally through the port. A distal region of the catheter body assumes first or second configurations when the working element is retracted into the catheter body.
