MRI Interventions' ClearPoint System Used By Physicians In Laser Ablation Procedures For Patients With Epilepsy And Brain Tumor

MEMPHIS, Tenn., April 2, 2013 /PRNewswire/ -- MRI Interventions, Inc.'s (OTCBB: MRIC) ClearPoint ® Neuro Intervention System continues to extend its role as an integrated platform for performing a wide range of minimally-invasive neurological procedures, as physicians are now using the ClearPoint system in connection with laser ablation therapy.  The ClearPoint system provides guidance for the placement and operation of instruments or devices during the planning and operation of neurological procedures within the MRI environment, making it an ideal delivery platform to place laser probes to precisely targeted areas in the brain. 

Using the ClearPoint system to deliver laser ablation therapy, the surgeon sees and selects the desired neurological target, aims the ClearPoint SmartFrame ® targeting device, and watches under real-time MRI guidance as the laser probe is advanced through the SmartFrame device to the target.  Energy is then delivered to the target area through the laser probe, and that energy destroys the unwanted tissue.  Because the procedure is performed within the MRI environment, the surgeon is able to monitor brain tissue temperature throughout the procedure, and to verify that the targeted tissue has been destroyed.

Dr. Hooman Azmi at Hackensack University Medical Center was the first surgeon to couple the ClearPoint system with laser ablation technology in connection with the treatment of malignant brain tumors called glioblastoma multiforme (GBM). Dr. Robert Gross at Emory University Hospital was the first to use the ClearPoint system and laser ablation technology to treat patients with epilepsy.  Both Drs. Azmi and Gross originally had brought the ClearPoint system into their hospitals to assist with the placement of deep brain stimulation (DBS) electrodes.

"The combination of these two technologies – the ClearPoint MRI-guided system and laser ablation – has the potential to provide minimally-invasive treatment options for patients whose epileptic seizures cannot be controlled with medications," said Dr. Gross.
