A steerable electromagnetic catheter comprises a catheter body, tip section, and control handle. The catheter body has proximal and distal ends and at least one lumen extending therethrough. The control handle is fixedly attached to the proximal end of the catheter body. The tip section comprises tubing having proximal and distal ends and at least one lumen extending therethrough. The proximal end of the tip section is fixedly attached to the distal end of the catheter body. A tip electrode is mounted at the distal end of the tip section and has at least one blind hole extending from its proximal end. The blind hole is in communication with at least one lumen in the tip section. An electromagnetic sensor is mounted in the tip section. The catheter further comprises a means for deflecting the tip section.

[ I claim:] [1.] A steerable catheter comprising:a catheter body having proximal and distal ends and at least one lumen extending therethrough;a control handle fixedly attached to the proximal end of the catheter body;a tip section comprising:a flexible tubing having proximal and distal ends and at least one lumen extending therethrough, wherein the proximal end of the tip section is fixedly attached to the distal end of the catheter body;a tip electrode having a distal end and a proximal end mounted at the distal end of the flexible tubing, wherein the tip electrode has a blind hole extending from its proximal end into the electrode to a position proximal its distal end, said blind hole in communication with at least one lumen in the tip section; andan electromagnetic sensor having proximal and distal ends, wherein the distal end of the sensor is mounted at least partially within the blind hole in the tip electrode;means for connecting the electromagnetic sensor to an imaging system; andmeans for deflecting the tip section.
