    摘要： The present invention relates to a system for facilitating treatment via a vascular wall defining a vascular true lumen (116) containing an occlusion (120) therein, the system comprising:
    an intramural orienting device (3400) including an outer shaft (3410) connected to a proximal end (3446) of an orienting element (3440), and an inner shaft (3420) extending through the outer shaft (3410) and the orienting element (3440), wherein a distal end of the inner shaft (3420) is connected to a distal end (3448) of the orienting element (3440);
    wherein the inner shaft (3420) includes a lumen extending therethrough to a side port (3425) adjacent the orienting element (3440);
    wherein the orienting element (3440) comprises a metallic tube with cuts made to define two wings (3442A, 3442B), wherein contracting the proximal end (3446) of the orienting element (3440) toward the distal end (3448) of the orienting element (3440) extends the wings (3442A, 3442B) outwardly in a substantially planar manner.

    摘要： The present invention relates to a medical device, comprising a handle with a main part and a movable part, wherein at least one of the main part or the movable part includes a hub to couple an energy source to the handle, a shaft including a shaft lumen and a distal end, wherein the distal end includes a passive electrode, an active electrode, wherein the active electrode includes an electrode lumen in fluid communication with an outlet at a distal tip to deliver fluid, and a proximal support coupled to and partially overlapping with the active electrode, wherein the proximal support includes a proximal support lumen that fluidly couples the shaft lumen to the electrode lumen, wherein movement of the movable part of the handle controls a position of the proximal support relative to the shaft and also controls a position of the active electrode relative to the passive electrode.
