Industry-leading Commitment to Clinical Research

We are driven to improve and extend the life of patients suffering from neurological diseases by providing a minimally invasive option for patients. Our commitment to clinical research is an essential and integral part of our mission and is demonstrated in our clinical trial work and the resulting clinical evidence.

NeuroBlate Clinical Evidence

Monteris Medical has sponsored the collection of acute and long-term outcomes with the NeuroBlate System across eight clinical studies.1 All currently enrolling studies are conducted under post-market protocols due to the commercial nature of the device.

LITT Clinical Evidence

Published data has greatly expanded in recent years. Prospective outcomes for Laser Interstitial Thermal Therapy (LITT) are published for brain tumors, radiation necrosis and drug-resistant epilepsy.

Clinical Guidelines and Societal Recommendations on LITT

The National Comprehensive Cancer Network® (NCCN) issued guidelines on the use of LITT (Central Nervous System Cancers, V1.2023, BRAIN-B), indicating LITT may be considered for patients who are poor surgical candidates (craniotomy or resection). Potential indications include recurrent brain metastases, radiation necrosis and recurrent glioblastoma.

Societal recommendations supporting the use of LITT for people with brain tumors and drug-resistant epilepsy have been issued by the American Association of Neurological Surgeons (AANS), the College of Neurological Surgeons (CNS), and the American Society of Stereotactic and Functional Neurosurgery (ASSFN). Because updates to the medical guidelines can take several years, the joint position statements represent an evidence-based summary and the societies’ current thinking, to guide health care providers in the use of magnetic resonance (MR)-guided LITT for the management of selected patients who may benefit from a minimally invasive laser procedure.


REMASTer: Randomized Controlled Trial (NCT05124912)

The Recurrent Brain Metastases After SRS Trial (REMASTer) study is a randomized, post-market multi-center study investigating the efficacy of two sets of treatment algorithms in brain metastases (BM) patients at the time of radiographic progression evidence after stereotactic radiosurgery (SRS), with or without resection. Currently Enrolling.

LAANTERN: Laser Ablation of Abnormal Neurological Tissue Using Robotic NeuroBlate System Trial (NCT02392078)

Monteris is the sponsor of the largest laser ablation registry for brain: LAANTERN—a prospective, multi-center study of outcomes for patients undergoing the NeuroBlate procedure. LAANTERN enrolled over 1,000 patients in the United States and Canada and followed them for a 5-year period. Not currently enrolling.

LAANTERN study has produced a number of peer-reviewed publications highlighting NeuroBlate® utilization, safety, quality of life, health economics, and procedural outcomes including survival and seizure freedom. Published articles from LAANTERN:

Investigator Initiated Research Support

Monteris has an active investigator initiated research program, which allows us to partner with investigators in their LITT early phase research. For more information contact


Monteris provides technology for neurosurgeons, which allows them to ablate (destroy with heat), brain structures such as brain tumors, radiation necrosis, and epileptic foci. Monteris technology includes the NeuroBlate System, AtamA, and MiniBolt devices, which may be used together to apply the focused laser energy with little or no effect on surrounding healthy tissue. The NeuroBlate System provides clinicians a tool that offers near real-time control and MRI visualization of the therapy during laser ablation treatment.

All brain surgeries carry risk. Possible adverse events include, but are not limited to, hematoma, embolic events, edema, bleeding, cerebral spinal fluid (CSF) leakage, infection, unintended major tissue damage and permanent neurological deficits. Prior to using these devices, please review the Instructions for Use for a complete listing of indications, contraindications, warnings, precautions and potential adverse events.
