Accuro 3S

The Rivanna Medical Accuro 3S is a Class II ultrasonic pulsed echo imaging system designed for point-of-care diagnostic ultrasound, particularly for musculoskeletal imaging and needle/catheter placement guidance like neuraxial anesthesia. Its core innovation lies in the SpineNav-AI™ image processing software, which leverages machine learning to achieve high accuracy in lumbar spine anatomical annotation and epidural region indication, thereby enhancing procedural guidance for healthcare professionals.

The Rivanna Medical Accuro 3S device, classified as an Ultrasonic Pulsed Echo Imaging System (Class II), has received a determination of substantial equivalence to legally marketed devices, allowing its marketing for diagnostic ultrasound imaging. It is designed for use by trained healthcare professionals at the point of care within hospital or medical clinic environments, supporting clinical applications such as musculoskeletal imaging and guiding needle or catheter placements, with a primary application being neuraxial anesthesia guidance. This diagnostic system incorporates B-mode imaging and features the SpineNav-AI™ image processing software, which leverages machine learning to assist in lumbar spine imaging assessments. Non-clinical safety testing confirmed the device's compliance with relevant standards across acoustic output, cleaning, electrical, thermal, mechanical, and electromagnetic compatibility. Crucially, the SpineNav-AI™ software underwent specific validation testing using a diverse dataset, successfully demonstrating high accuracy in anatomical annotation and precise indication of the epidural region.
