Overall dimensions and seat dimensions: the proposed device has minor difference with the predicate device, which will only affect the appearance of the device but not affect the safety and effectiveness of the subject manual wheelchair. The subject manual wheelchair has already been tested for performance according to ISO 7176-1/-3/-5/-7/-8/-11/-13/-16/-22 and complies with the standards. Therefore, the subject manual wheelchair is as safe, effective and performs as well as the legally marketed predicate device. b. Rear Wheel : the size, tire material and rim diameter of the proposed device are similar with the predicate device. The handrim material of the proposed device is different with the predicate device. The handrim of the proposed device has been tested for biocompatibility according to ISO 10993-10 and {7}------------------------------------------------ complies with the requirements. Therefore, the subject manual wheelchair is as safe, effective and performs as well as the legally marketed predicate device. c. Min. Turning Diameter, the proposed device has smaller min. turning diameter than predicate device, which meet the design specification and has better flexibility than predicate device. The subject manual wheelchair has already been tested for performance and complies with the standards. Therefore, the subject manual wheelchair is as safe, effective and performs as well as the legally marketed predicate device. d. Armrest: the armrest of the proposed device is solid PP material while the armrest of the predicate device is padded. The PP material has been tested for biocompatibility according to ISO 10993-10 and it was proven to be safe. Therefore, the subject manual wheelchair is as safe, effective and performs as well as the legally marketed predicate device. e. Casters: the proposed device has minor difference with the predicate device, which will only affect the appearance of the device but not affect the safety and effectiveness of the subject manual wheelchair. The material of casters is different with the predicate device. The PP material has been tested for biocompatibility according to ISO 10993-5 and ISO 10993-10 and it was proven to be safe. Therefore, the subject manual wheelchair is as safe, effective and performs as well as the legally marketed predicate device. f. Weight of wheelchair, the proposed device has minor difference with predicate device, this different is caused by different framework design, but it could not affect the safety and effectiveness of proposed device. The subject manual wheelchair has already been tested for performance and complies with the standards. Therefore, the subject manual wheelchair is as safe, effective and performs as well as the legally marketed predicate device. g. Although the stowage length, stowage width and stowage height of the predicate device are not available, the folding mechanism of the proposed device and the predicate device is same. In light of the slight difference of overall dimension between the proposed device and the predicate device, and the same folding way of the two devices, the difference of the stowage length/width/height between the devices can be considered as minor, which will not affect the safety and effectiveness of proposed device. Therefore, the subject manual wheelchair is as safe, effective and performs as well as the legally marketed predicate device. | Item | Proposed Device | Predicate Device | Result | |--------------------------|---------------------------------------------------------------|---------------------------------------------------------------|--------| | Performance Test | Comply with ISO<br>7176-1/-3/-5/-7/-8/-11/-13/-15/<br>-16/-22 | Comply with ISO<br>7176-1/-3/-5/-7/-8/-11/-13/-1<br>5/-16/-22 | Same | | Biocompatibility | Comply with ISO 10993-1 | Comply with ISO 10993-1 | Same | | Label<br>and<br>labeling | Conforms to FDA Regulatory<br>Requirements | Conforms to FDA Regulatory<br>Requirements | Same | Table 3 Safety Comparison of Proposed and Predicate Devices ## G.
