The device description clearly details numerous hardware components including a battery, motor, gear box, brakes, wheels, frame, and a physical control lever and speed knob. While it mentions a controller (which likely contains software), the device is fundamentally a physical mobility aid with integrated hardware.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to provide mobility to adult persons. This is a physical function, not a diagnostic test performed on samples taken from the body.
- Device Description: The description details a power scooter with mechanical and electrical components for movement and control. It does not mention any components or processes related to analyzing biological samples.
- Lack of IVD Indicators: The document does not mention any of the typical characteristics of an IVD, such as:
- Analysis of biological samples (blood, urine, tissue, etc.)
- Detection or measurement of analytes
- Diagnosis, monitoring, or screening of diseases or conditions based on sample analysis
- Reagents, calibrators, or controls
The device is clearly a mobility aid designed for personal transportation.

Device Description
The Merits Yoga Power Scooter, S542, is battery powered, rear transaxle driven and is controlled by the PG S-Drive 45amp controller. The user interface is a wig-wag control lever and a speed knob on the control panel. S542 is powered by one 12 VDC 11.5Ah battery. The batteries are charged by 4.3A off-board charger connect with 3-pin Microphone Connector to charging socket on the rear shroud. The approximate driving range on fully charged batteries is up to 18km (11.3mi). The scooter frame is a welded aluminum construction and includes 2 rear wheels with drive units (including motor, gear box, and brake), a removable battery pack, a front wheel set which consists of 2 wheels for better stability and a tiller to control its turning direction. When the user activates the wig-wag control lever, the controller receives a signal to release the brakes. With the brakes released, the scooter is allowed to move forwards or backwards. When the user releases the control lever, the scooter slows to a stop and the brakes are automatically re-engaged. The solenoid electromechanical brakes allow the user stop by letting go of the control lever. The frame is designed to be foldable for easy storage and transportation. For safety reason, this solenoid electromechanical brake is designed as normal close type. In case of the brake or electrical failure, the brake shoe will re-engage automatically to prevent the movement of the scooter. The upholstery of the device complies with ISO 7176-16:2012 Resistance to ignition of postural support devices. The device can be operated on dry, level surfaces composed of concrete, blacktop, or asphalt under normal driving conditions.

Substantial Equivalence Discussion
The Merits S542 Scooter is substantially equivalent to the Merits Travel Ease Electric Scooter, Model Pioneer 5 (K013788). Both products are battery power, motorized, seating systems designed for use with electric scooters. Performance characteristics and drive mechanisms are similar and all have the same intended function and use which is to provide mobility to adult persons limited to a sitting position and capable to operate a few simple controls. Additional, they are all constructed from the same basic materials, have the same basic operational principles and all use DC batteries as their source of power. The comparison table is as follow:

There are some difference between S542 and its predicate device raise:
- a. Turning Radius: The device passed ISO 7176-2:2001(Determination of Dynamic Stability of electric wheelchairs): Item 10.3 and 10.4. So there is no deleterious affection of safety and effectiveness about the difference on Turning Radius with predicated device.
- b. Dimension: The device passed ISO 7176-1:1999 (Determination of Static Stability) and ISO 7176-2:2001(Determination of Dynamic Stability of electric wheelchairs). So there is no deleterious affection of safety and effectiveness about the difference on Dimension with predicated device.
- c. Range up to: The travel range of S542 is better than the predicated device.
- d. Max. Speed: The device has passed ISO 7176-2:2001(Determination of Dynamic Stability of electric wheelchairs) & ISO 7176-8 (Requirements and test methods for static, impact and fatigue strengths) test (Please see Appendix IV: Test reports). So there is no deleterious affection of safety and
