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 lumen therethrough. A tip section comprising a flexible tubing is mounted at the distal end of the catheter body. The tip section has a needle passage extending therethough. 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 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 needle passage. The injection needle is longitudinally slidable so that its distal end can extend beyond the distal end of the tip section upon suitable manipulation of the needle control handle.
