Epidural positioning device Accuro

Overview
Accuro is a portable, handheld neuraxial guidance system that combines Multi-Frequency BoneEnhance Image Reconstruction with SpineNav3D AI-enabled image recognition to improve bone-to-tissue contrast and automatically identify spinal midline, interlaminar space and epidural depth. The device delivers automated image interpretation and graphical insertion guidance to support spinals and epidurals at point of care.

Key benefits

• Enhanced bone-to-tissue contrast using Multi-Frequency BoneEnhance Image Reconstruction (reported 5–10× improvement).
• Automated identification of spinal midline, interlaminar space and epidural depth with SpineNav3D AI (reported success rates >94%).
• Graphical insertion guidance (midline indicator and cross-hair) to locate optimal needle entry.
• Option to mark needle placement or perform real-time needle guidance using the Accuro Locator accessory.

Features

• Automated, AI-enabled image interpretation.
• Multi-Frequency BoneEnhance Image Reconstruction for superior bony landmark visualization.
• SpineNav3D AI image recognition for epidural detection and depth measurement.
• Portable, handheld form factor with rotatable touchscreen.
• Pocket-sized, battery-operated for point-of-care workflow.
• Compatible with Accuro Locator for needle guidance and marking.
• Clinically studied with published data supporting increased first-attempt success and reduced paresthesia/wet-tap in difficult anatomies.

Use cases
Designed to assist neuraxial procedures in patients with challenging anatomy, including morbid obesity, prior spinal surgery or instrumentation, scoliosis, and other situations where bony landmarks are difficult to palpate. Clinical examples include improved first-attempt epidural placement in high-BMI patients and patients with spinal hardware or scoliosis.

Customer update
Rivanna will discontinue sales of new Accuro systems on December 31, 2026; eligible final system orders must be placed by December 1, 2026. Existing warranties and service plans will continue to be honored according to their written terms.
