Monteris NeuroBlate system

New data from two separate studies looking at the use of the NeuroBlate system from Monteris for brain lesions were presented at the American Association of Neurological Surgeons (AANS) 84th Annual Scientific Meeting.

Data evaluating customised 3D printed mini-platforms in laser interstitial thermal therapy (LITT) were also presented at the meeting.

Sujit S Prabhu, professor in the Department of Neurosurgery at The University of Texas MD Anderson Cancer Center (Austin, USA), delivered an oral presentation on 27 patients titled “Laser-Induced Thermal Therapy in Treatment of Recurrent Intracranial Metastatic Disease post-Stereotactic Radiosurgery.”

Veronica L Chiang, associate professor of Neurosurgery and of Therapeutic Radiology,
director of Stereotactic Radiosurgery, and medical director at the Yale-New Haven Hospital Gamma Knife Center (New Haven, USA), reported preliminary results titled “Laser Ablation After Stereotactic Radiosurgery.”

Additionally, Joseph S Neimat, professor and chairman at the Center for Advanced Neurosurgery in the Department of Neurological Surgery at University of Louisville (Louisville, USA) presented results from a study evaluating customized 3D mini-platforms in LITT. In a poster presentation, titled “Use of Customized 3-D Printed Platforms for Targeting in Laser Interstitial Thermal Therapy,” described the use of custom 3D mini-platforms to target LITT in 9 patients. Such platforms have been used extensively to accurately position probes used in deep brain stimulation surgery and offer a promising approach to increase the precision of catheter placement within the brain during LITT procedures. The results show that laser placement was successful in all 9 patients, with good accuracy. There were no complications or intraoperative frame instability. The total frame cost per procedure was less than US$6,000. Study investigators concluded that customised 3D printed platforms can provide accurate, simple, and rapid implantation of laser catheters for LITT procedures. They also note that the versatility of the design platform should enable future modifications as LITT technology evolves.

“These results demonstrate that customized printed 3D platforms can provide accurate, non-complex and rapid implantation of the laser catheter for performing LITT,” says Neimat. “The versatility of the platform allows for both growth and flexible, iterative design modifications as LITT technology continues to evolve.”
