The device is described as a manual wheelchair intended for mobility, not for treating or curing medical conditions.
No
Explanation: The device is a manual wheelchair providing mobility, not a diagnostic tool used to identify or analyze medical conditions.
No
The device description clearly outlines a physical manual wheelchair with various adjustable hardware components. There is no mention of software as the primary or sole component of the device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to provide mobility for physically challenged persons. This is a physical aid, not a diagnostic test performed on biological samples.
- Device Description: The device is a manual wheelchair with various adjustable components. It does not involve analyzing biological specimens.
- Lack of IVD Characteristics: There is no mention of analyzing blood, urine, tissue, or any other biological sample. There is no mention of detecting diseases, conditions, or states of health through in vitro examination.
IVD devices are used to perform tests on samples taken from the human body to provide information about a person's health. This wheelchair is a medical device that provides physical support and mobility.

Device Description
The tool-less wheel chair is a light weight manual chair. Which is intended to provide mobility based on an individual users' needs and capabilities. It is available in a range of sizes (dimensions) to allow fit to a particular user, and is adjustable in various ways, including: The key change covered by this submission is the ability to make several routine adjustments quickly, and without the need for additional parts or the use of tools. These typical routine adjustments include:
CHAIR STANCE
Camber - The angle of the wheels with respect to the side frame of the chair
Forward / aft - wheel position Axle location with respect to front/back of chair
Toe in/ toe out - The amount by which the distance between the front of the two rear wheels varies from the distance at the back.
Track Width - The distance between the wheels
Caster height - Adjusting the relative height of the front of the chair or adjusting to accommodate for rear camber adjustments and/or seat height.
RIDER POSITION
Back Rest Angle - The angle of the back of the chair with respect to the side frame
Squeeze - The angle or slope of the seat with respect to the side frame
The combination of chair stance and rider position determine the center of gravity, a factor on the performance of the chair.
Center of Gravity - The center of Mass (the point at which the entire weight of a body may be considered as concentrated so that if supported at this point the body would remain in equilibrium in any position)
These factors are interrelated and must be adjusted to complement each other to tune the chair’s performance.
Adjustable from 16 degrees forward Back Rest Angle to 8 degrees back, the angle from the seat to the backrest upholster. This angle is usually adjusted when the squeeze is adjusted.
Any one of four preset settings, Seat Angle or Squeeze changing the squeeze fine tunes the ride height for propelling and reach. This adjusts the comfort level of the user, and also raises or lowers the center of gravity.
Center of Gravity The balance point. Different for each individual occupying a chair. This adjustment is made by the rider to his personal sense of balance, and reactivity. Center of gravity is adjusted by changes to wheel width, forward/aft axle position, seat angle, seat depth (weight distribution) , and caster height.
Chairs are configured to customer orders when sold. Configuration to order allows flexibility. Features such as width, depth, and back height are specific configuration includes chair accessories and desired safety features. Any combination of features from the approved matrix may be configured to create the chair features needed by a given rider It is the rider and the health care professional that determine the appropriate configuration for the users needs. As the individuals condition or size change, other components or accessories may be ordered and the chair reconfigured to meet the evolving needs of its user.
Tool less wheelchairs consists of typical components found on most wheelchairs, such as backrest, seat frame, cushion, footrest and casters. Accessories include items such as armrests, positioning belts, backpacks, seat pouches, oxygen tank holders, IV poles, etc.
Many of these components may become available in a range of sizes, shapes, angles, forms, materials or coverings. These variations allow the chairs to be configured to meet the specific desires and needs of the user. .
The chairs have excellent performance indoors and are very good outdoors over surfaces that are firm ad free of large obstacles and long steep inclines. That makes them an ideal maneuverable, light duty, light weight "Get out there chair".
Warnings, cautions and contraindications are detailed in the users manual.

PERFORMANCE FACTORS
The impact of each adjustment has a different performance implication for the rider.
Currently adjustable to five positions ranging from Camber zero to sixteen degrees the camber is easy to adjust as the rider lines up color coded marks to obtain the desired angle. Wheels straight up (0 degrees) provides the most narrow chair, but is less stable. As the top of the wheels are brought closer together, the bottoms become farther apart. This increases the wheel base, and creates improved stability. It also allows the chair to turn with less effort. A rider may want stability on the basketball court, and maneuverability in the office. To adjust to changing needs, he may set the camber high for the basketball court, low to maneuver tight office spaces, and mid range for daily home use.
Forward / aft wheel position Currently adjustable over a four inch range, placement of the rear wheels in the forward position on the splined frame section makes the chair very responsive and maneuverable. However, it also makes it very susceptible to tipping over backwards. Sunrise recommends the use of anti tip tubes when the rear wheels are in the forward positions.
Usually desired to be neutral for best Toe in/ toe out alignment. Alignment is built into the locked variable positions. It is also tied to caster adjustment. (Casters must be set to same height or chair will be misaligned.
Adjustable over a four inch range, a Wheel Base or Track Width wider wheel base increases stability. Width can be adjusted to weigh gain or other environmental changes to allow enough space between the rider and the wheel.
Caster height.

COMPARISON OF DEVICE CHARACTERISTICS TO PREDICATE(S):
The chairs have similar performance features, the Tool-less allows chair adjustment quickly, any time, any where, with no tools required.
These adjustments are routinely made today, but usually require disassembly and often the exchange of one part for another with different dimensions or geometry. The toolless wheel chair achieves the same goal through the use of self contained, variable position, adjustments.
The predicate devices including the Quickie GPS allow the dealer to make adjustments to these factors relating to chair stance and rider position. The tool-less chair's construction allows these routine adjustments, without tools.
Testing:
| This device has been tested to both ISO7176 and ANSI/RESNA

Safety:
An analysis of complaints against Quickie manual chairs was completed and charted. This analysis was supported by a literature search which was conducted by a third party to determine the number of complaints. MDR's and recalls that have been reported to the FDA concerning wheelchairs in general. This information was summarized, and presented in a Management Review report dated 2/20/97. The data and charts are included as Appendix C. The analysis demonstrated common issues across all manufacturers product lines, and varying levels approximately comparable to relative market share.

Conclusion:
The Tool-less Wheel Chair, shares performance features and technology with a number of devices already legally marketed within the United States. The design changes that allow the user to adjust his chair without the use of tools do not introduce issues of safety or efficacy. They introduce convenience. Therefore, the Tool-less wheel chair is substantially equivalent to the predicate devices.
