Abstract
Devices and methods for exploiting intramural (e.g., subintimal) space of a vascular wall to facilitate the treatment of vascular disease, particularly total occlusions. For example, the devices and methods disclosed herein may be used to visually define the vessel wall boundary, protect the vessel wall boundary from perforation, bypass an occlusion, and/or remove an occlusion.

3. A system for facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein, the system comprising:
-
an intramural orienting device having an elongate shaft with a central lumen extending therethrough to a distal opening, the device terminating at a distal tip configured for controlled deflection; a first actuation member connected to the distal tip and extending to a proximal end of the shaft for causing deflection of the distal tip upon movement of the first actuation member; an orienting element having a first collapsed configuration and a second expanded, substantially planar configuration; and a second actuation member connected to a portion of the planar orienting element and extending to a proximal end of the shaft for causing expansion of the orienting element upon actuation of the second actuation member. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
