## Indications for Use

To provide improved mobility, both indoors and outdoors, for persons who have adequate upper body strength suitable for manual steering, and who have a medical condition that impairs their ability to stand for periods of time or to walk.

## Device Story

Navigator I is a motorized 3-wheeled vehicle for mobility-impaired individuals. Input: user-operated manual steering and 6-position variable speed control via tiller. Operation: 24V DC permanent magnet motor, rear-wheel drive, powered by two 12V sealed lead-acid batteries. Features: 16" front wheels, 5.4" ground clearance, 27.5" turning radius, and patented Torsional Elements connecting front/rear frames to allow 5° rotation for stability. Output: motorized propulsion. Used in homes, shopping malls, or trails; operated by the patient. Benefits: improved mobility, active lifestyle, and enhanced side-tip resistance via occupant-initiated swing-out anti-tip wheels.

## Clinical Evidence

Bench testing only. No clinical data provided. Safety and effectiveness were established through mechanical testing of the Torsional Elements and anti-tip wheel system to demonstrate improved side-tip resistance and stability.

## Technological Characteristics

Motorized 3-wheeled vehicle; 24V DC permanent magnet motor; two 12V sealed lead-acid deep cycle batteries; 16" front wheels; 11.5" rear drive tire; Torsional Elements for frame articulation (up to 5°); manual steering tiller; electronic motor controller; 6-position variable speed control; curb climbing ability (5.5").

Intended use - To provide improved mobility, both indoors and outdoors, for persons who have adequate upper body strength suitable for manual steering, and who have a medical condition that impairs their ability to stand for periods of time or to walk.

Description of the device - Navigator I was designed to assist individuals with limited mobility to maintain an active lifestyle. Its manual steering, high-torque four brush motor with rear wheel drive, large diameter (16") front wheels, high ground clearance (5.4"), full circle turning radius (27.5"), side to side anti-tip resistance, and curb climbing (5.5") ability make it a versatile vehicle equally adept in the shopping mall, on firm surface wilderness trails, or in the close quarters of a restaurant or home kitchen. Navigator I is a blended hybrid drawine elements from both scooters and wheelchairs, to meet desired features requested by long term scooter users. It does this while still maintaining the three-wheel scooter configuration with manual steering and anti-tip wheels adjacent to the single steering wheel. Navigator I is an clectronically controlled motorized 3-wheeled vehicle employing a rear single wheel remotely steerable motor drive system (11.5" tire). It employs a 24 Volt DC permanent magnet motor powered by two 12 Volt scaled lead acid deep cycle batteries. The rigid Front Frame Assembly holds the two batteries, mounts the two front 16" diameter wheels, the two front hand controlled parking brakes, the swing up front foot rests, the electronic motor controller, and the steering arm with handle incorporating the 6-position variable speed-control. The Rear Frame Assembly is made up of the rear motor drive, the swing out Anti-tip wheels, the rear bearing block assembly and pivot wheel assembly. The Front and Rear Frame Assemblies are connected together by two semi-rigid Torsional Elements™ (relatively rigid to a vertical load, but allowing limited rotation), which also support the scat block mounting assembly. The Torsional Elements™ allow limited twist (similar to the Articulation Beam in the Pride Jazzy, K945936) to occur between the Front and Rear Frame Assemblics up to 5° of rotation, at which point one Anti-tip wheel with the ground. This greatly enhances side to side stability when driving Navigator I over rough terrain, since Navigator I is smothly transformed from three wheels to four wheels with ground contact on all four wheels.

Substantial equivalence - The Navigator I design is shown to be substantially cauvalent to the motorized threewheeled scoolers that were classified in class II under 21 CFR Section 890,3800. The basic three-wheeled scooter design is augmented with a patented frame design with anti-tip wheels that improve stability. Navigator I is a blended hybrid drawing features primarily from scooters, with some mechanical wheelchair features to improve safety and effectiveness, as outlined in the list of specific features from the predicate devices listed above and detailed in this 510(k).

Safety and effectiveness - The Navigator I Powered Scooter is substantially equivalent to the technology cmployed in the predicate devices listed in this 510(k). Navigator I docs not raise any new issues of salety and clectiveness. The occupant initiated swing-out anti-tip wheels allow the occupant to readily improve resistance to side-tip and the Torsional Elements™ provide both a smooth ground engagement of the anti-tip wheels and a side-tip warning mechanism via front wheel pickup, which we have shown by testing to significantly improve occupant safety.
