An injection catheter comprises a catheter body (12) comprising a flexible tubing having proximal and distal ends and at least one lumen therethrough. The catheter has a tip section (14) comprising a flexible tubing (19) having proximal and distal ends. The proximal end of the tip section is mounted at the distal end of the catheter body. A needle control handle (17) is provided at the proximal end of the catheter body. An injection needle (46) extends through the tip section, catheter body, and needle control handle and has a proximal end attached to the needle control handle and a distal end within the tip section. The injection needle is longitudinally slidable within the tip section so that its distal end can extend beyond the distal end of the tip section upon suitable manipulation of the needle control handle. The injection needle consists of plastic.
