Globus' ExcelsiusGPS is currently the closest rival to Medtronic's spine robot, but other device companies are looking for a slice of the pie. NuVasive is developing a robotic application for its Pulse integrated spine platform, Brainlab's Cirq spine robot received FDA clearance last year and Accelus — the latest company to enter the spine robotic market — is launching its Remi robotic navigation system. The next generation of spine robots aim to address some of the well-documented challenges of the legacy systems, such as extended setup and teardown time, procedural workflow disruptions, large footprints and high cost. Robots currently on the market cost about $1 million, but some companies also offer lease and bundle options with other products.
