Autonomix Medical said on September 30 that FDA supported a Class II route for its sensing platform at a pre-submission meeting. The company plans to claim substantial equivalence to a device already cleared. It is targeting US clearance in about 15 months, subject to development and validation work and to FDA review. Autonomix named neither the predicate nor a lead indication.

The platform is a catheter-based microchip sensing array built to pick out faint biological signals. It is aimed at transvascular diagnosis and treatment of peripheral nervous system disease, and Autonomix lists cardiology, hypertension and chronic pain as targets. Splitting the sensing array off as a standalone 510(k) gets a platform on the market before the therapy data lands.
