Patent number: 9301705Abstract: A system and method for using magnetic resonance imaging to increase the accuracy of electrophysiologic procedures includes an invasive combined electrophysiology and imaging antenna catheter which includes an RF antenna for receiving magnetic resonance signals and diagnostic electrodes for receiving electrical potentials. The combined electrophysiology and imaging antenna catheter is used in combination with a magnetic resonance imaging scanner to guide and provide visualization during electrophysiologic diagnostic or therapeutic procedures, such as ablation of cardiac arrhythmias. The combined electrophysiology and imaging antenna catheter may further include an ablation tip, and be used as an intracardiac device to deliver energy to selected areas of tissue and visualize the resulting ablation lesions.Type: GrantFiled: December 30, 2011Date of Patent: April 5, 2016Assignee: Johns Hopkins University School of MedicineInventors: Henry R. Halperin, Ronald D. Berger, Ergin Atalar, Elliott R. McVeigh, Albert Lardo, Hugh Caikins, Joao Lima

Patent number: 7822460Abstract: A system and method for using magnetic resonance imaging to increase the accuracy of electrophysiologic procedures is disclosed. The system in its preferred embodiment provides an invasive combined electrophysiology and imaging antenna catheter which includes an RF antenna for receiving magnetic resonance signals and diagnostic electrodes for receiving electrical potentials. The combined electrophysiology and imaging antenna catheter is used in combination with a magnetic resonance imaging scanner to guide and provide visualization during electrophysiologic diagnostic or therapeutic procedures. The invention further provides a system for eliminating the pickup of RF energy in which intracardiac wires are detuned by filtering so that they become very inefficient antennas. An RF filtering system is provided for suppressing the MR imaging signal while not attenuating the RF ablative current. Steering means may be provided for steering the invasive catheter under MR guidance.Type: GrantFiled: October 26, 2007Date of Patent: October 26, 2010Assignee: Surgi-Vision, Inc.Inventors: Henry R. Halperin, Ronald D. Berger, Ergin Atalar, Elliot R. McVeigh, Albert Lardo, Hugh Calkins, Joao Lima
