Abstract
A steerable injection catheter comprises a catheter body, a deflection control handle, a needle control handle, a tip section, and a means for deflecting the tip section by manipulation of the deflection control handle. A moveable injection needle extends from the needle control handle and through the catheter body and tip section. The needle may be moved out of the distal tip of the catheter by manipulation of the catheter control handle. The catheter also comprises a tip electrode mounted at the distal end of the tip section. An electrode lead wire is electrically connected to the tip electrode. The lead wire extends through a lumen in the tip section, through a lumen in the catheter body and into the deflection control handle. The injection catheter also includes an electromagnetic mapping sensor which is disposed within the distal tip of the catheter for providing tip location information.
