Beschreibung
Zusammenfassung:	Intravascular catheters with fluoroscopically visible indicium of rotational orientation. The catheter includes an elongate flexible tubular body, having a proximal end, a distal end and a tubular side wall defining at least one lumen extending therethrough. At least first and second opposing pairs of radiopaque rings are embedded in the side wall, spaced axially apart from each other. A first transverse axis extending through the first pair of rings is rotationally offset from a second transverse axis extending through the second pair of rings. The rings may be supported by a subassembly integrated into the wall of the catheter. The subassembly may include a tubular body having a plurality of aperture portions connected by intervening hinge portions. In one implementation, the catheter is a reentry catheter.
