1. Apparatus for intracardiac drug administration, comprising a catheter which is inserted into a chamber of the heart and brought into engagement with a site in the heart wall, the catheter comprising:
- at least one position sensor at a distal end of the catheter for determining position and orientation coordinates of the distal end of the catheter by generating signals responsive to the position of the distal end of the catheter within the heart; and
a drug delivery device, which administers a desired dose of a therapeutic drug at the site determined responsive to the signals from the position sensor.
