No
The document does not mention AI, ML, or any related technologies in the device description, intended use, or performance studies. The focus is on functional electrical stimulation and cycle ergometry.
Yes
The device is intended for the relaxation of muscle spasms, prevention or retardation of disuse atrophy, increasing local blood circulation, and maintaining or increasing range of motion, all of which are considered therapeutic applications.
No
The device description and intended use outline the device's function as a functional electrical stimulation (FES) cycle ergometer for rehabilitation, explicitly stating its purpose for muscle relaxation, prevention of atrophy, increasing blood circulation, and maintaining range of motion. None of these functions involve diagnosing a medical condition.
No
The device description explicitly lists multiple hardware components, including a motorized cycle ergometer, an FES controller/stimulator, stimulation cables, and electrodes.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The RT300-S and RT300-SP are functional electrical stimulation (FES) cycle ergometers. They are used for physical rehabilitation by applying electrical stimulation to muscles and providing cycling assistance.
- Intended Use: The intended uses listed (relaxation of muscle spasms, prevention of disuse atrophy, increasing local blood circulation, maintaining or increasing range of motion) are all related to physical therapy and rehabilitation, not diagnostic testing of biological samples.
- Device Components: The components listed (cycle ergometer, FES controller/stimulator, electrodes, cables, database interface, arm crank, pulse oximeter interface) are consistent with a physical rehabilitation device, not an IVD.
The device interacts with the patient externally (via electrodes) and assists with physical activity. It does not analyze biological samples for diagnostic purposes.

Device Description
The RT300-S is a Functional Electrical Stimulation (FES) cycle ergometer which is composed of:
- a motorized cycle ergometer (RTI part number SA100047 for adults and SA100044 for children)
- an FES controller / stimulator (RTI part number SA100090)
- a stimulation cable which connects the controller / stimulator to cutaneous electrodes (RTI part number SA100091)
- cutaneous electrodes (12 electrodes for 6 stimulation channels, RTI part number FA100015)
- an interface to a remote database for the storage and retrieval of therapy settings and the storage of therapy session logs
- an optional motorized arm crank (RTI part number PP102663)
- an interface to a pulse oximeter for the display and recording of pulse and SpO2 levels and provision of alarming based on the data.
This system allows a person with impaired lower extremity movement to undertake cycle ergometry both actively (utilizing FES evoked lower extremity muscle contractions) and passively (utilizing power developed by the ergometer's motor).

Testing the pulse oximeter interface: The RT300-S pulse oximeter interface was validated with four able bodied individuals.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non clinical testing to determine equivalence has been primarily composed of the following tests:
- Review of user documentation for predicate device: Ensure that equivalent functionality is specified and implemented in the new device.
- Review of 510(k) submission for predicate device: Confirm technical specifications for completion of predicate details in comparison tables
- Output characteristic measurement of new device: Confirm technical specifications for completion of new device details in comparison tables
- Conduct of system testing: Conduct system testing to verify performance to specification.
Clinical Test: Testing the pulse oximeter interface. Description: The RT300-S pulse oximeter interface was validated with four able bodied individuals.
RTI concludes that: The RT300-S has the same intended use as the predicate device. The RT300-S has the same output characteristics as the predicate device. The different technological characteristics do not raise new questions of safety and effectiveness. The safety and effectiveness of using a motor to simulate the predicate device's mechanical flywheel and provide passive cycling assistance has been extensively demonstrated in particular by the ongoing clinical use of the motorized ergometer without the stimulation component both in the European Union and in the U.S.A. The safety and effectiveness of the controller has been demonstrated over the development period of the RT300-S. The remote database enhances the safety and effectiveness of the system by ensuring that patients always commence a therapy session with their latest, accurate device settings.
In conclusion, RTI's clinical and non clinical testing has demonstrated that the RT300-S is as safe and effective as the predicate device.

Trade/Device Name: RT300-S and RT300-SP Regulation Number: 21 CFR 882.5810 Regulation Name: External functional neuromuscular stimulator Regulatory Class: II Product Code: GZI Dated: April 19, 2007 Received: April 20, 2007
Dear Mr. Barriskill:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set
