With the objective of giving electrophysiologists a better view of the heart during a catheter ablation procedure, Imricor Medical Systems, Inc. is developing magnetic resonance imaging (MRI) compatible electrophysiology tools for the treatment of cardiac arrhythmias. The company offers Vision MR EP Ablation Catheter that looks and performs as a conventional ablation catheter; and Horizon MR EP Recording System, which performs the recording and pacing function of conventional recording and pacing systems for use with MRI. The firm's products also allow electrophysiologists to perform cardiac electrophysiology procedures in the MRI lab to image a patient's heart. Closer to securing regulatory approval in Europe than in the US, with an active licensing program, some med-tech companies have used Imricor's technology to develop MRI compatible devices.,
