1. A method for accessing a wall of a blood vessel, the method comprising:
intravascularly positioning a distal portion of an elongated shaft of a treatment device in the blood vessel at a puncture site;
advancing a visualization device through a visualization lumen of the elongated shaft to identify the puncture site;
expanding an expansion member on the elongated shaft to move an exit port of a tool lumen of the elongated shaft to be substantially in line with a longitudinal segment of the wall of the vessel and place a tissue engaging surface of an open trough against the wall of the blood vessel, wherein the open trough extends distally from the exit port;
advancing a first tool through the tool lumen beyond the exit port to form an intramural pocket between at least a first portion and a second portion of the wall of the blood vessel; and
delivering a fluid into the intramural pocket via the first tool.
