MRI Interventions, developer of innovative platforms for performing minimally invasive surgical procedures in the brain and heart, has reported that data from the use of the company's ClearPoint(NYSE:R) Neuro Intervention System in "asleep" deep brain stimulation (NYSEARCA:DBS) surgery were recently presented during the 2013 Annual Meeting of the Congress of Neurological Surgeons (NYSE:CNS) in San Francisco.
The ClearPoint System is a navigation platform designed to provide surgeons with real-time, direct visualization during minimally invasive neurosurgical procedures. Dr. Paul Larson, neurosurgeon at the University of California, San Francisco (UCSF), presented at the meeting the accuracy results from a prospective study of 60 patients who underwent asleep DBS with the ClearPoint System.
"Almost every electrode was placed with a single pass to the brain," Dr. Larson stated after his presentation, "meaning we hit the target the first time in each of those cases. More importantly, we hit the correct target based on the fact that no patients have returned for repositioning. We were able to do this through real-time image guidance enabled by ClearPoint."
In addition, Dr. Fiona Gupta, neurologist at Hackensack University Medical Center (HUMC), presented clinical outcomes of 11 patients who underwent asleep DBS with the ClearPoint System at HUMC.
"We've been very impressed with the outcomes we have seen so far," said Dr. Gupta. "My patients have had dramatic improvement in their movement scores. Many of these patients would not have had the awake surgery, so these results were made possible by iMRI asleep DBS."
Lastly, Dr. Jill Ostrem, neurologist at UCSF, presented preliminary data regarding outcomes with asleep DBS from a UCSF clinical study.
"While our data is preliminary at this point, I can say that the patients we've assessed so far are doing very well," Dr. Ostrem stated. "Initial clinical outcomes are in line with outcomes in conventional awake procedures, which is exactly what we want to see at this point."
