Claim Text:
1. A method for separating two or more portions of a vessel wall, the method comprising: intravascularly delivering a dissection assembly to a dissection site adjacent the vessel wall, the dissection assembly including an elongated tubular member having a slanted distal face and an exit port positioned along the distal face, wherein the distal face has a distal-most edge and a proximal-most edge, and wherein a central longitudinal axis of the exit port is offset from a central longitudinal axis of the elongated tubular member such that the exit port is positioned along the distal face closer to the distal-most edge than the proximal-most edge, and wherein the elongated tubular member further includes forming an opening in the vessel wall with the elongated tubular member; advancing the exit port through the opening; and separating vessel wall tissue by ejecting fluid through the exit port while a portion of the distal face remains outside of the opening.
