An injection catheter is provided. The injection catheter comprises a catheter body comprising a flexible tubing having proximal and distal ends and at least one lumen therethrough. A tip section comprising a flexible tubing having proximal and distal ends is mounted on the distal end of the catheter body. A needle control handle is provided at the proximal end of the catheter body. The needle control handle comprises an outer body having a piston chamber therein, a piston having two ends, wherein one end of the piston is slidably mounted within the piston chamber, and a compression spring in the piston chamber between the outer body and the piston. An injection needle extends through the tip section, catheter body, and needle control handle. The injection needle has a proximal end attached to one of the outer body and the piston and a distal end within the distal end of the tip section. Longitudinal force applied to one of the outer body and the piston causes longitudinal movement of the other of the outer body and the piston, thereby compressing the compression spring, resulting in distal movement of the injection needle relative to the catheter body so that the distal end of the injection needle extends outside the distal end of the tip section.
