More Information

Not Found

No
The description focuses on the mechanical and electrical components of a standard mobility scooter, with no mention of AI or ML capabilities.

No
Explanation: A therapeutic device is designed to treat or alleviate a medical condition. This device is a mobility aid for individuals restricted to a seated position, not for treatment.

No
The device description and intended use clearly state that it is an electric scooter for mobility, not for diagnosing medical conditions.

No

The device description clearly outlines a physical, battery-operated electric scooter with hardware components like wheels, a seat, armrests, and hand controls. It is not solely software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is clearly stated as providing mobility to persons restricted to a seated position. This is a physical function, not a diagnostic one.
  • Device Description: The description details a mobility scooter with wheels, a seat, controls, and a battery. There is no mention of analyzing biological samples or providing diagnostic information.
  • Lack of IVD Indicators: The document explicitly states "Not Found" for key indicators typically associated with IVDs, such as:
    • Mentions image processing
    • Mentions AI, DNN, or ML (often used in diagnostic analysis)
    • Input Imaging Modality
    • Anatomical Site (IVDs often target specific anatomical sites for sample collection)
    • Indicated Patient Age Range (while some IVDs have age ranges, the absence here is consistent with a non-IVD)
    • Description of training/test sets for performance evaluation (crucial for validating diagnostic accuracy)
    • Key Metrics (Sensitivity, Specificity, etc. - essential for evaluating diagnostic performance)

The performance testing mentioned (EMC Report) relates to electrical and mechanical safety and performance, not diagnostic accuracy.

In summary, the device's function and the information provided strongly indicate it is a mobility aid, not an in vitro diagnostic device.

The device is intended for medical purposes to provide mobility to persons restricted to a seated position.

Description of the device:

The WU'S 4-WHEELED SCOOTER WT-XL is an indoor / outdoor electric scooter that is battery operated. It has a base with four-wheeled with a seat, armrests, and a front basket.

Summary for substantial equivalence comparison:

The intended uses, similar batteries, cruising range, back upholstery, armrest types, and warranty period between the new device WT-XL4 and the predicate device WT-L4 are all the same. Especially the electronic systems between two devices, except the recharge are the different suppliers, they are the same suppliers and all passed by the UL certificated, for instance the controller, the batteries and recharge and switching power supplier. Thus the same safety level for the two devices is assured.

The major differences existing of the two scooters are the new device WT-XLA is huger for the patients that weight limit are 550 lbs and the predicate device WT-L4 is for general use for the 300 lbs patients. Thus the new device needs bigger the overall dimension, the size of tires, and the weights are differences between the two devices. The overall appearance differences are not safety aspect. So the new device is substantially equivalent to the predicate devices in this aspect.

Dear Dr. Ke Min Jen:

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.
