Abstract
A device and method for intravascular dissection of a body lumen, and particularly a blood vessel wall, is disclosed herein. One aspect of the present technology, for example, is directed toward a tubular elongated member having a lumen therethrough, wherein the elongated member includes a distal region configured to be positioned within a blood vessel wall. The distal region can include an angled distal face having a distal-most edge configured to puncture the vessel wall and a proximal-most edge. The member can include an exit port fluidly coupled to the lumen, and positioned along the distal face between the distal-most edge and the proximal-most edge. A central longitudinal axis of the exit port can be offset from a central longitudinal axis of the elongated member such that the exit port is closer to the distal-most edge than the proximal-most edge.
