Abstract
An injection catheter is provided. The catheter comprises a catheter body comprising a flexible tubing having proximal and distal ends and at least one needle passage extending therethrough. The needle passage has a proximal region having a proximal diameter and a distal region having a distal diameter less than the proximal diameter. A needle control handle is provided at the proximal end of the catheter body. An injection needle extends through the catheter body and needle control handle and has a proximal end within the needle control handle and a distal end within the needle passage. The injection needle is longitudinally slidable within the catheter body so that its distal end can extend beyond the distal end of the catheter body. A needle stop is mounted on a portion of the injection needle that is positioned within the proximal region of the needle passage. The needle stop has a distal end that is sized to prevent passage of the portion of the injection needle on which the needle stop is mounted from passing into the distal region of the needle passage. The needle stop limits the distance that the injection needle can be extended beyond the distal end of the catheter body.
