A robotically controlled laser probe is placed through a small burr hole and delivers heat while MR thermometry shows the ablation zone in real time, offering a minimally invasive alternative to open resection for brain tumours, radiation necrosis and drug-resistant epilepsy. NeuroBlate is FDA cleared and marketed in the US. In 2026 the company published the LAANTERN prospective registry in the Journal of Clinical Oncology, covering 787 oncology patients treated at 25 centres. In March 2026 Monteris closed a USD 28 million Series E led by InnovaHealth Partners and Birchview Capital, with OSF Ventures, the Colorado University Healthcare Innovation Fund and Madryn Asset Management participating, and secured a USD 35 million credit facility from Trinity Capital.","asOf":"2026-09-10","links":[{"label":"Official website","url":"https://www.monteris.com"},{"label":"Series E growth equity press release (March 2026)","url":"https://www.prnewswire.com/news-releases/monteris-medical-secures-28-million-in-growth-equity-to-accelerate-revenue-and-innovation-in-minimally-invasive-neurosurgery-302711794.html"},{"label":"Trinity Capital USD 35 million credit facility (March 2026)","url":"https://www.prnewswire.com/news-releases/trinity-capital-inc-provides-35-million-in-growth-capital-to-monteris-medical-to-support-neurosurgical-technology-advancements-302711455.html"},{"label":"LAANTERN 787-patient publication (2026)","url":"https://www.prnewswire.com/news-releases/monteris-medical-announces-publication-of-landmark-study-on-787-brain-tumor-patients-treated-with-neuroblate-laser-interstitial-thermal-therapy-litt-302854905.html"}],"tags":[],"related":[],"cancers":["glioblastoma"],"sections":["surgery","devices"],"technologies":["thermal-ablation","mri","robotic-surgery"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":["Website returns HTTP 403 to curl but loads via WebFetch.
