#### Substantial equivalence comparison discussion:

We know from the above table that the intended use between two devices is the same; and they are from the same LERADO group and the same manufacturer. Mainframes of two devices are not foldable and all meet the strength and fatigue tests, thus they are similar for the material aspects. The overall dimensions are similar. The weight capabilities, maximum speed, suspension of cross brace, footplates, armrest, and the warranty are all the same. Back upholstery material is also the same fabric.

Especially, the electronic systems of two devices, for instance the motor, batteries, and charger are from the same supplier, and both are UL-certified. For the electronic controller, the predicate device uses the Dynamic DA series and the subject device use Dynamic Shark series, and both are UL-certified. Thus the same safety level for the two devices is assured.

Incline capabilities for the two devices are the same. The subject device and the predicate device can both drive under 6 degrees of incline. We place the limit of 6 degrees of climbing incline on the page 2 of the Owner's Manual and the user is not allowed to operate the device on the incline over the specified angle. The safety levels of the two devices are the same when operating the devices on the adequate inclines. They are substantially equivalent.

{6}------------------------------------------------

Image /page/6/Picture/0 description: The image shows the word "LERADO" in a stylized font. The letters are in black and are spaced apart. The letter "A" is replaced by a black triangle. Below the word "LERADO" is the text "LERADO DESIGNS" in a smaller font.

The cruising ranges per charge are different; and the subject device is 12.4 miles and 22.5 miles for the predicate device. Certainly the real range depends on the practical environmental conditions, i.e., loading weight, driving surface, incline angle, and temperature. For the real life use, the two devices are substantially equivalent.

To sum up, the major differences existing between the two devices are the overall dimensions and cruising ranges. The overall appearance differences are not safety aspect. Thus the new device is substantially equivalent to the predicate devices in this aspect.

Based on the above the information and the analysis, we know that the subject device and the predicate device have the same intended use, the same technological aspects and only minor dimensions and material differences exist. We believe that FDA can decide the subject device and the predicate device are substantially equivalent.

Dear Dr. Ke-Min:

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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
