Indications for Use
The Extreme X8 Power Wheelchair is a battery-operated device with wheels that is intended for medical purposes to provide mobility to persons restricted to a sitting position who have the capability of operating a power wheelchair.
Device Story
The Extreme X8 is a battery-powered, electric motor-driven wheelchair for indoor and outdoor use on varied surfaces (concrete, asphalt, grass, gravel). It features a steel frame, four-wheel drive, and two seating options (MPS or Rehab). The user operates the device via a joystick and hand control buttons. The device transforms electrical energy from batteries into mechanical motion via four 24V direct drive gear motors. It includes electromagnetic, regenerative braking. Accessories include lights, luggage racks, and various cushions. The device is intended for use in residences and care facilities. It provides mobility to users with limited physical function, allowing them to navigate environments independently. Healthcare providers or therapists may assist in selecting seating configurations (Rehab option) to meet specific patient needs.
Clinical Evidence
Bench testing only. Performance verified against ISO 7176 standards for static/dynamic stability, braking, energy consumption, dimensions, obstacle climbing, and electrical safety (EMC). Biocompatibility evaluated per ISO 10993-1 and ISO 10993-5.
Technological Characteristics
Steel frame; 4-24V, 4-pole direct drive gear motors; 2x 73Ah AGM 12V batteries; electromagnetic/regenerative braking; joystick controller. Software: R-Net (PGDT). Dimensions: 45.25" x 37". Ground clearance: 4". Max speed: 6.2 mph. Range: 15.5 miles. Complies with ISO 7176 series and IEC 62304.

Dear Michelle Rubin-Onur:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrl/cfdocs/cfpmn/pmn.cfm identifies.combination product submissions. 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.
{1}------------------------------------------------
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); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531 -542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

### COMPARISON OF TECHNOLOGICAL CHARACTERISTICS
Magic Mobility believes that the Extreme X8 Power Wheelchair is substantially equivalent to the predicate device based on the information summarized here:
The subject device has a similar design and dimensions and uses similar or identical materials as the device cleared in K090350. The subject device has the same intended use and similar technological characteristics (i.e., base technology and OEM joystick control) to the devices cleared in K093050 and K172384. The subject device has the same intended use environment, including off road capabilities, as the device cleared in K090350. The subject device uses the same software as the device cleared in K172384. The Extreme X8 Power Wheelchair has undergone testing to ensure that any differences in technological characteristics (i.e., battery, castor wheels, and no anti-pitch mechanism) do not affect safety and effectiveness when compared to the predicate device.
