A catheter for delivering an agent to an injection site in a wall of a patient's body lumen, with an elongated shaft having a needle-through lumen slidably containing a needle therein, and an expandable member on the distal shaft section which has a collapsed configuration and a radially expanded configuration. In the radially expanded configuration, the expandable member supports the shaft in a position spaced away from the body lumen wall, and the needle slidably exits the needle-through lumen in the extended configuration through the port spaced away from the body lumen wall as a portion of the expandable member maintains the position of the port section of the shaft in the body lumen. The expandable member typically has an open-walled, helical, or lobed configuration providing a perfusion path along the expandable member.

An agent delivery catheter having two or more axially spaced balloons and an inflation bridge providing fluid communication between the two balloons. The catheter generally has a proximal balloon, a distal balloon, and a tube defining an inflation bridge lumen which is located in part within the inflatable interiors of the balloons, and which extends therebetween, and which has a proximal port within the proximal balloon interior and a distal port within the distal balloon interior to thereby provide for inflation of the distal balloon by placing the distal balloon interior in fluid communication with the proximal balloon interior of the shaft.
