DEVICES, SYSTEMS, AND METHODS FOR CONTROLLED HYDRODISSECTION OF VESSEL WALLS

摘要

A device and method for intravascular dissection of a body lumen, and particularly a blood vessel wall (VW), is disclosed herein. One aspect of the present technology, for example, is directed toward a tubular elongated member (110) having a lumen therethrough, wherein the elongated member (110) includes a distal region configured to be positioned within a blood vessel wall (VW). The distal region can include an angled distal face (120) having a distal- most edge (126) configured to puncture the vessel wall (VW) and a proximal-most edge. The member can include an exit port (124) fluidly coupled to the lumen, and positioned along the distal face between the distal-most edge (126) and the proximal-most edge. A central longitudinal axis of the exit port (124) can be offset from a central longitudinal axis of the elongated member such that the exit port is closer to the distal-most edge (126) than the proximal-most edge.
