No
The summary does not mention AI, ML, or any related concepts like training sets, test sets, or specific performance metrics associated with AI/ML models. The device description focuses on hardware components and basic functional electrical stimulation.
Yes
The device's intended uses, such as "Relaxation of muscle spasms," "Prevention or retardation of disuse atrophy," "Increasing local blood circulation," and "Maintaining or increasing range of motion," are therapeutic in nature. The device also includes an FES controller and stimulators which are used for therapy.
No
The RT600 is described as a Functional Electrical Stimulation (FES) upright elliptical ergometer intended for general rehabilitation to relax muscle spasms, prevent disuse atrophy, increase local blood circulation, and maintain or increase range of motion. Its functions are therapeutic, not diagnostic. While it monitors pulse and SpO2, this is for display, recording, and alarming based on the data, not for diagnosing any condition.
No
The device description explicitly lists multiple hardware components including a motorized ergometer, FES controller, wireless stimulators, cables, electrodes, and a stimwear garment.
Based on the provided information, the RT600 is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use of the RT600 is for general rehabilitation purposes involving muscle stimulation and movement, not for the examination of specimens derived from the human body to provide information for diagnosis, monitoring, or screening.
- Device Description: The device description details a system for functional electrical stimulation and exercise, not for analyzing biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing blood, urine, tissue, or any other biological specimen. The device interacts with the body externally through electrodes and a garment.
- Predicate Device: The predicate device (RT300) is also a rehabilitation device, not an IVD.
Therefore, the RT600 falls under the category of a therapeutic or rehabilitation device, not an In Vitro Diagnostic device.

- a motorized upright ergometer (RTI part number SA211257)
- an FES controller with built in 6 channel stimulator (RTI part number SA109413)
- up to 5 additional wireless single channel stimulators (RTI part number FA106897)
- a stimulation cable which connects the controller / stimulator to cutaneous electrodes
- cutaneous electrodes (up to 22 electrodes for up to 11 stimulation channels)
- an interface to a remote database for the storage and retrieval of therapy settings and the storage of therapy session logs
- an interface to a pulse oximeter for the display and recording of pulse and SpO2 levels and provision of alarming based on the data
- a stimwear garment incorporating electrodes for lower extremity cycling in population ages 12 and above (RTI part number FA105486)
This system allows a person with impaired lower extremity movement to undertake upright elliptical ergometry both actively (utilizing FES evoked lower extremity muscle contractions) and passively (utilizing power developed by the ergometer's motor).

- Test or procedure: Review of 510(k) submission for predicate device; Description: Confirm technical specifications for completion of predicate details in comparison tables.
- Test or procedure: Output characteristic measurement of new device; Description: Confirm technical specifications for completion of new device details in comparison tables.
- Test or procedure: Conduct of system testing; Description: Conduct system testing to verify performance to specification.
Clinical Test: Testing the RT600 upright elliptical ergometer.
Description: The RT600 with 5 additional RT50 stimulation channels was validated with ten SCI individuals.
RTI concludes that:
The RT600 has the same intended use as the RT300 predicate device.
The RT600 has the same output characteristics as the predicate device. The RT600 utilizes the same control system as the predicate device including controller, motor controller and drive assembly. The different technological characteristics do not raise new questions of safety and effectiveness.
In conclusion, RTI's clinical and non-clinical testing has demonstrated that the RT600 is as safe and effective as the predicate devices.
