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. The catheter further comprises a tip section comprising a flexible tubing having proximal and distal ends, wherein the proximal end of the tip section is mounted at the distal end of the catheter body. A needle control handle is provided at the proximal end of the catheter body. An injection needle comprising elongated tubing extends through the tip section, catheter body, and needle control handle. The injection needle has a proximal end attached to the needle control handle, a distal region within the tip section, and an open distal end. The injection needle is longitudinally slidable within the tip section so that its distal region can extend beyond the distal end of the tip section upon suitable manipulation of the needle control handle. The distal region of the injection needle has at least one fluid port along its length. In use, fluid passes out of the needle through the open distal end and the at least one fluid port along the length of the distal region.
