Claim 0:
1. A system for providing transvascular access to an extravascular site, comprising:
an access catheter for supporting transvascular access, the access catheter comprising:
an elongate tubular body having a proximal end, a distal end, and a lumen extending between the proximal end and the distal end, the distal end comprising an atraumatic tip;
an inclined barrier within the lumen at a distal portion of the elongate tubular body;
an aperture passing through the inclined barrier, the aperture having an aperture diameter; and
a side exit port in the elongate tubular body, in communication with the lumen and located proximally adjacent to the inclined barrier, the side exit port having a transverse dimension at a longitudinally central portion of the side exit port, wherein the aperture diameter is less than the transverse dimension, wherein the access catheter further comprises a laterally expandable support carried on the elongate tubular body on an opposite side of the elongate tubular body from the side exit port and diametrically opposite to the side exit port, and wherein the laterally expandable support has an unexpanded state and an expanded state, and wherein the laterally expandable support is configured to expand from the unexpanded state toward the expanded state in a first radial direction against a first side of a vessel wall of a blood vessel, thus causing the side exit port and a portion of the elongate tubular body surrounding the side exit port to be forced in a second radial direction, opposite the first radial direction, such that the side exit port and the portion of the elongate tubular body are positioned against a second side of the vessel wall, opposite the first side.
