No
The device description and performance studies indicate a purely mechanical, manually operated wheelchair with no mention of AI or ML components.
Yes.
The device provides mobility for individuals with limited sitting ability, which is a therapeutic function.
No
The device description indicates it is a mechanical wheelchair, which is intended for mobility and does not perform any diagnostic functions.
No
The device description clearly states it is a mechanical wheelchair with physical components like a frame, seat, footrests, and wheels, indicating it is a hardware device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Definition of IVD: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Intended Use: The intended use of the YJ-011S Manual Wheelchair is clearly stated as providing mobility to persons limited to a sitting position. This is a physical aid, not a diagnostic test.
- Device Description: The description details a mechanical device for physical mobility, not equipment for analyzing biological samples.
- Lack of IVD-related information: The document does not mention any processes related to sample collection, analysis, reagents, or diagnostic results, which are characteristic of IVDs.
The YJ-011S Manual Wheelchair is a Class I medical device (based on the predicate device K201461, which is a Class I manual wheelchair) intended for physical support and mobility.

Device Description
The YJ-011S series is a mechanical wheelchair which is a manually operated device with wheels that is intended for medical purposes to provide mobility to persons restricted to a sitting position. It can be folded for transport by bringing the two sides together. The manual wheelchair incorporates a main frame, a seat, two adjustable footrests and four wheels.
The larger rear wheels have hand rims of slightly smaller diameter projecting just beyond the tire. These allows the user to maneuver the chair by pushing them on without requiring them to grasp the tires. The manual wheelchairs have brakes that bear on the tires of the rear wheels and two push handles at the upper rear of the frame to allow for manual propulsion by an assistant.
Main Components: Main frame, back upholstery, seat upholstery, handgrip, armrest, front wheel, rear wheel, hand rim, crossbar, footplates, brake, leg rest.
The device can be operated indoors, or outdoors on dry, level surfaces composed of concrete, blacktop, or asphalt under normal driving conditions.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical tests were conducted to verify that the subject device met all design specifications and was Substantially Equivalent (SE) to the predicate device. The test results demonstrated that the proposed device complies with the following standards: ISO 7176-1:2014, Wheelchairs - Part 1: Determination of static stability, ISO 7176-3:2012 Wheelchairs - Part 3: Determination of effectiveness of brakes, ISO 7176-5: 2008 Wheelchairs - Part 5: Determination of overall dimensions, mass and maneuvering space, ISO 7176-7: 1998 Wheelchairs - Part 7: Measurement of seating and wheel dimensions, ISO 7176-8: 2014 Wheelchairs - Part 8: Requirements and test methods for static, impact and fatigue strengths, ISO 7176-11: 2012 Wheelchairs - Part 11: Test dummies, ISO 7176-13: 1989 Wheelchairs - Part 13: Determination of coefficient of friction of test surfaces, ISO 7176-15: 1996 Wheelchairs - Part 15: Requirements for information disclosure, documentation and labeling, ISO 7176-16:2012 Wheelchairs - Part 16: Resistance to ignition of postural support devices, ISO 7176-22:2014 Wheelchairs — Part 22: Set-up procedures.
Biocompatibility testing was conducted in accordance with the 2020 FDA guidance Use of International Standard ISO 10993-1, "Biological Evaluation of Medical Devices – Part 1: Evaluation and testing within a risk management process." Testing included: Cytotoxicity (ISO 10993-5:2009), Sensitization (ISO 10993-10:2010), Irritation (ISO 10993-23:2021). The testing supports the biocompatibility of the patient-contacting device materials that were shown to be non-cytotoxic, non-irritating, and non-sensitizing.

Dear Eva Li:
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/cdrh/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.

Discussion :
| Similar*1: | Compared to the predicate device, the subject device adds two skirt guards which installed to the sides of the seat frame under the arm rests to provide a barrier between the occupant and the wheels. This feature can prevent occupant's clothes from getting caught in the wheels. This feature will not raise any new risk of safety or effectiveness. |
|---|---|
| Different*2: | Compared to the predicate device, the subject device has different value on the unfold size, stowage size, device weight, capacity, seat width, seat height, seat depth, tire size. However, the subject has passed the and , so the above different will not raise any new risk of safety or effectiveness. |
| Different*3: | Compared to the predicate device, the subject device's back is adjustable, and the arm can't be flipped. These differences will not raise any new risk of safety or effectiveness. |
| Similar*4 | The stimulation test in ISO 10993-23 replaces the stimulation test in ISO 10993-10:2010. It will not raise any new risk of safety or effectiveness. |
