Hansen Medical has made an equity investment in Advanced Cardiac Therapeutics (ACT), and secured exclusive rights to ACT intellectual property for certain robotic applications.

ACT, based in Laguna Beach, Calif., has developed a technology that is designed to measure the temperature in a lesion during cardiac ablation procedures. The Mountain View, Calif.-based Hansen said its Sensei Robotic Catheter System's electrophysiologic mapping catheters uses medical robotics technology to provide control of catheter movement inside the heart.

ACT said its patented Microwave Radiometry System could be incorporated into standard and irrigated cardiac catheters. A catheter with ACT's technology would have the potential to assist electrophysiologists by providing real-time feedback about energy delivery by the catheter. ACT's technology has not been clinically tested and has not received regulatory approval, Hansen said.
