Monteris Medical Raises $28 Million Series E, Secures New $35 Million Credit Facility to Accelerate Growth

New updates have been reported about Monteris Medical.

Monteris Medical has strengthened its balance sheet with $28 million in Series E equity financing and a new $35 million credit facility, capital that will support expansion of its NeuroBlate System for minimally invasive, MR-guided laser neurosurgery. The company plans to use the equity proceeds to scale its U.S. commercial presence and fund technology development, clinical research, and selective geographic expansion, positioning the business for accelerated revenue growth.

The round was led by existing investors InnovaHealth Partners and Birchview Capital, with new participation from OSF Ventures and the Colorado University Healthcare Innovation Fund, both tied to health systems already using NeuroBlate, while prior credit partner Madryn Asset Management also joined as a major equity investor. Citing strong operating performance and a near-term path to profitability and positive cash flow, Monteris refinanced and retired its previous facility with Madryn in favor of a larger, lower-cost, longer-duration facility from Trinity Capital, which described Monteris as a category leader in minimally invasive neurosurgery, and both OSF Ventures’ Mayank Taneja and Madryn’s Alex Marcantonio have joined the board, reinforcing governance depth as the company seeks to capture rising demand for laser interstitial thermal therapy in brain tumors and drug‑resistant epilepsy across nearly 130 North American health systems.
