#### Intended Use

The intended use of the Invacare Model M71 Power Wheelchair is to provide mobility to persons limited to a sitting position, that have the capability of operating a powered wheelchair.

#### Technological Characteristics and Substantial Equivalence

#### A. Device Description

The Invacare Model M71 power wheelchair is a battery powered, motor driven device with the intended function and use of providing mobility to those persons limited to a sitting position that have the capability of operating a power wheelchair. It is a rigid or "non- folding" type power wheelchair, with mid wheel drive capability.

The wheelchair frame is of rigid or non-folding type design. The wheelchair frame is of rigid or non-folding type design. The frame consists predominately of round 1 1/4 " diameter x .07 wall, steel tubing. The frame is of welded construction. The chair can be disassembled into 6 pieces without the use of tools for transport in vehicles that are not equipped with wheel chair lifts and ramps. To easy re-assembly, the mating parts are color-coded or labeled at the joints. Painted shrouds are used to conceal the wheelchair frame, motors and controller.

The wheelchair is designed with front wheel, walking beam type suspension. That is, the front swivel casters are mounted to two separate front extension frame members, and are thus, independent of each other. Each extension frame member pivots independently in a vertical plane about a horizontal axis. This allows the chair to better negotiate small obstacles such as curbs, or ramps, from a complete stop. The rear casters pivot as well, and also serve as wheelchair anti-tippers.

The Invacare M71 wheelchair incorporates a direct, drive, which includes two separate right angle gear motors. Because it is a direct drive system, there are no belts, pulleys, chains, sprockets or the like, to periodically adjust or maintain. Both gearboxes are sealed and maintenance free.

The Invacare M71 wheelchair is powered by two 12 volt, U-1 deep cycle gel cell batteries. The operating range; between battery re-charging is approximately 12 miles. Range will vary with battery condition, surface terrain and operator weight. The On Board Charger is standard.

#### B. Substantial Equivalence

The Invacare Model M71 Power Wheelchair is substantially equivalent to Invacare Corporations' Action Arrow K991168, June 25, 1999), Invacare Corporations' Ranger II M6 Power Wheelchair (K002157, August 25, 2000), and Permobil's Chairman Front Wheel Drive Power Wheelchair (K960951, April 4, 1997).

#### PERFORMANCE DATA

As required by FDA's July 26, 1995, draft publication entitled "Guidance Document for the Preparation of Premarket Notification [510(k)] Applications for Mechanical and Powered Wheelchairs, and Motorized Three- Wheeled Vehicles", the Invacare M71 Power Wheelchair was tested in accordance with ISO EMC Draft Standard 7176-14 (Titled "Draft ISO EMC Group Proposal: Electromagnetic Compatibility Addition" And Dated April 3, 1995) for powered wheelchairs and motorized scooters. In all instances, the Invacare M71 Power Wheelchair met the required performance criteria and functioned as intended.
