Accelus Announces Successful First Surgeries Using Remi Robotic Navigation System with LineSider Spinal System


Accelus, a privately held medical technology company focused on accelerating the adoption of minimally invasive surgery (MIS) as the standard of care in spine, today announced the successful completion of the first cases utilizing its Remi™ robotic targeting and navigation platform with its LineSider™ posterior fixation system. Renowned neurosurgeon and Accelus Chief Robotics Officer Kevin Foley, MD, who was a key contributor in the development of the robotic navigation system, performed the first Remi case using LineSider at Baptist Memorial Hospital-Memphis in December 2021. Since then, successful procedures using Remi with LineSider have also been performed by Dr. Kornelis Poelstra at Sunrise Hospital and Medical Center in Las Vegas, Dr. Pierce Nunley at Specialists Hospital Shreveport, and Dr. Richard Hynes at Melbourne Regional Medical Center.

Remi is a comprehensive robotic targeting and navigation platform that provides robotic-assisted pedicle screw placement for surgeons performing lumbar spine fixation. It is designed to provide the same precision and accuracy as legacy spinal robotic systems but with a smaller footprint, optimized procedural workflow, shorter setup and teardown times, and economically accessible pricing.

“The goal with Remi was to address the limitations of current spinal robotic systems—inefficient workflow, large footprints and high cost—while providing the same accuracy,” said Dr. Foley. “LineSider adds to this efficiency with its versatile and streamlined instrumentation. I have been extremely pleased with my first cases utilizing Remi with the LineSider system.”

The Remi Robotic Navigation System is comprised of a workstation that serves as the primary user interface, an ultra-lightweight nearfield camera and a four-pound robotic targeting platform. Both the camera and targeting platform are attached to the operating room table, minimizing the system’s footprint. Its camera also features a wide angle of capture designed to track instrumentation throughout the surgical field and minimize the line-of-sight issues commonly experienced with legacy spine surgery robotic platforms. Remi’s workstation features a touch-screen computer that receives the intraoperative 3-D images and automatically registers the navigation system to the patient’s anatomy. The computer sits atop a 30-inch by 30-inch system cart that is easily transportable and provides storage for all the system’s components when not being used in surgery. This compact footprint makes it suitable for use in all facilities, including ASCs and hospitals with smaller operating rooms.

“Remi represents a substantial evolution in robotic spine surgery as we desired greater efficiency for our robotic-assisted cases,” said Dr. Poelstra, an orthopedic and neurological spine surgeon, founder of The Robotic Spine Institute of Las Vegas and a long-term pioneer of MIS robotic technology. “Remi seamlessly integrates with my surgical workflow due to its fast setup time and provides highly accurate and consistent screw placement to help reduce variability and improve my patient outcomes. It has been great fun using it in my OR!”

Remi is designed to simplify surgical workflow and provide procedural efficiencies. In a study published in The Cureus Journal of Medicine in 2021, the Remi robotic targeting and navigation system was determined to have significantly shorter procedure workflow duration while maintaining equivalent accuracy as compared to the most common alternative robotic spine platform1. The average total procedure time using the Remi system was 36.6 minutes compared to a total procedure time of 55.0 minutes using an alternative legacy robotic system.

“We believe these procedural efficiencies will offer significant economic benefits to facilities, in addition to its already attractive price point,” said Chris Walsh, CEO and Co-founder of Accelus. “Our goal is to accelerate the move to minimally invasive spine surgery, and we believe these advantages will make Remi easily accessible to cost-constrained facilities, such as ASCs, and eventually international markets.”

Dr. Nunley, Director of the Spine Institute of Louisiana and Chairman of the American Board of Spine Surgery, recently performed the world’s first four-level surgery using the Remi with the LineSider system.

“Remi’s simplified, intuitive design made it easy to incorporate into my procedural workflow,” Dr. Nunley said. “Its rapid system positioning and efficient setup and breakdown may even provide the potential to treat more patients. I also like the fact that it helps me perform an MIS procedure with reduced need for interoperative fluoroscopic images, helping reduce radiation exposure for my patients and staff. This is potentially disruptive and a ‘game changer’ compared to other current robot technologies.”
