Rhovica Neuroimaging is developing SoNav, a bedside navigation system for external ventricular drain catheter placement in emergency neurosurgery. The company focuses on patients with severe head trauma, intracranial bleeding, or other causes of elevated intracranial pressure, where rapid ventricular access is needed to drain cerebrospinal fluid and monitor pressure.

SoNav uses integrated sensors and real-time visualization to guide catheter insertion directly at the bedside. The system is designed to support accurate EVD placement in emergency and neurocritical-care settings, while also enabling monitoring of brain ventricles after placement. Rhovica has raised CHF 2.3 million to accelerate SoNav development and move the system toward clinical adoption.

Rhovica targets neurosurgeons and neurocritical-care teams managing acute patients who need fast intracranial pressure relief. The company is best understood as a focused neurosurgical navigation startup addressing one of the most common and technically variable emergency procedures in neurocritical care.
