A full CGCI Suite was installed at the University Hospital of La Paz in Madrid, Spain in order to begin a 20 patient human trail. Under the direction of noted cardiologist and Principal Investigator, Dr. Jose Merino who is the Director of the Arrhythmia and Electrophysiology Research Unit at the hospital, and with the assistance of Dr. Eli Gang, the first phase of the study consisted of 20 patients in which a highly detailed map of the heart would be created along with specific key target points within the various chambers being identified. Once completed, the catheter was removed to its starting point and then guided robotically by CGCI back to the heart and to each identified target location.

The results of Phase One testing was successfully completed in January of 2011 and Phase Two trials of the human study commenced. The Phase Two diagnostic expanded the study to an additional 20 patients undergoing the same test protocols. Again the results proved CGCI could outperform any existing robotic system on the market in its ability to track, target, and return to target on a repeated basis in less time and with less post-procedural side-effects.
