April 22, 2026, located in VirginiaThe Virginia Spine Institute (VSI) team at Reston Hospital Center (HCA Virginia system) announced the completion of the world's first clinical use of Medtronic's Stealth AXiS Autopilot surgical robot.The surgeons were Christopher Good, Colin Haines, and Ehsan Jazini, three spinal surgeons. The patient underwent staged surgeries, including single-level direct lateral interbody fusion (DLIF), three-level posterior pedicle screw fixation with laminectomy, and bilateral sacroiliac joint fusion.The real-time segment tracking, integrated navigation, and robotic guidance functions of Stealth AXiS were used during the surgery.

This marks the first time Stealth AXiS has been utilized in a real clinical setting since receiving FDA 510(k) clearance for spinal indications in February 2026 and subsequent approval for cranial and ENT indications in March.

# Product Positioning: Iterating from Mazor to Platform-level Integration

The core positioning of Stealth AXiS is to integrate preoperative planning, intraoperative navigation, and robotic execution into a single platform, replacing the previous workflow that required multiple independent systems to collaborate.This system is built on Medtronic's existing Mazor robotics and StealthStation navigation technology but features significant upgrades at the architectural level.

Key technical features include:

• LiveAlign Segment Tracking——Medtronic calls it an "industry first," enabling real-time intraoperative tracking of the motion of each vertebral segment, surgical adjustments, and changes in patient alignment without the need for repeated fluoroscopic imaging. This feature addresses the core pain point in spinal surgery where vertebral displacement during the operation (especially in multi-level surgeries) causes a mismatch between preoperative planning and actual anatomy. Traditional systems rely on static reference frames, whereas Stealth AXiS uses multi-sensor fusion to track individual vertebrae.

• Modular Design——Support hospitals to deploy as needed, starting with navigation functions and gradually expanding to robot-assisted applications, adapting to both hospital and ASC (Ambulatory Surgery Center) scenarios.

• AI-Assisted Architecture——Supports advanced planning and visualization for pre-operative, intra-operative, and post-operative procedures, integrated into Medtronic's AiBLE intelligent ecosystem.

• Cross-departmental expansion——The same platform has obtained FDA approval for three indications: spine, cranium, and ENT, which represents a differentiated strategy in the field of spinal surgical robotics.

In addition, on April 9, 2026, GE HealthCare announced the commercial launch of the digital integration of its bkActiv intraoperative ultrasound system with Stealth AXiS, primarily targeting the "brain shift" issue in cranial surgeries. This integration allows real-time ultrasound images to be connected to the navigation platform in a plug-and-play manner.

# Competitive Landscape: Spine Robots Enter Multi-Platform Parallel Period

The launch of Stealth AXiS has further evolved the "two-strong" competitive landscape in the U.S. spinal surgery robotics market. Medtronic previously competed in the market with the Mazor X Stealth Edition, and the Stealth AXiS represents a generational replacement in its product line rather than a new entrant.

Comparison of Major Spinal Surgery Robot Competitors in the U.S. Market

Globus Medical (which expanded in size after acquiring NuVasive in 2024) remains a major competitor to Medtronic in terms of installed base and market penetration. Gabelli's investment research report estimates that Globus has approximately 500 ExcelsiusGPS systems installed globally by the end of 2024. In 2024, Globus also launched the ExcelsiusHub navigation system and the Excelsius XR augmented reality navigation headset, further expanding its product portfolio. Stryker’s Mako Spine received approval in mid-2024, focusing on pedicle screw placement, and is currently in the early stages of commercial promotion.

Notably, Medtronic has chosen to"Platform Integration + Cross-Department Reuse"As a core competitive strategy —— the same hardware platform simultaneously covers spine, craniocerebral, and ENT, which differs from Globus Medical's path of expanding from spine to joint areas (ExcelsiusFlex received FDA approval for total knee replacement in April 2025).

# The Signal Significance of the First Surgery

It took about two months from approval to the first surgery, and the execution site was chosen to be a community hospital under the HCA Virginia system rather than a large academic medical center. This choice may reflect Medtronic'sThe Design Intent of the Stealth AXiS Promotion Pathway in Non-Academic Institutions and ASC Scenarios.The first surgery was a multi-level complex procedure (DLIF + three-level posterior fixation + bilateral sacroiliac joint fusion), covering both lateral and posterior approaches, serving as a practical test for the system's multi-scenario adaptability.

Surgeon feedback has mainly focused on real-time segment tracking, improved accuracy, and reduced radiation exposure, but no quantitative data has been disclosed yet. As the first use report, the reference value of this feedback is limited. What needs to be followed up on are multicenter usage data and comparative results with the Mazor X Stealth Edition.

Medtronic completed within the first four months of 2026"Dual Indication Approval - Cross-Enterprise Imaging Integration Commercialization - World's First Clinical Use"The pace is proceeding at a faster rate. Whether Stealth AXiS can substantially replace the installed base of Mazor X and gain market share in direct competition with ExcelsiusGPS depends on the accumulation of clinical data and the efficiency of installed base conversion.
