Merlexi Craft Bariatric series of manual wheelchairs
The Merlexi Craft Bariatric series of manual wheelchairs are intended for use to empower physically challenged persons by providing a means of mobility. This includes temporary and permanent conditions for which manual wheelchairs are generally prescribed for use. In particular, the Merlexi Craft Bariatric wheelchairs are intended for users up to 425 pounds. They are not for MRI environment use.
Not Found
Due to the nature of the provided document, which is a letter from the FDA regarding a 510(k) premarket notification for a medical device (manual wheelchairs), the requested information about acceptance criteria and a study proving those criteria are met is not present in the document.
This document is primarily concerned with confirming that the Merlexi Craft Bariatric series of manual wheelchairs is substantially equivalent to legally marketed predicate devices, and it outlines regulatory requirements and general controls for marketing such a device.
Here's why the requested information is not found:
- Acceptance Criteria and Device Performance: The letter states the device is "substantially equivalent" to predicate devices. This means it has similar technological characteristics and is intended for the same use as a device already on the market. It does not provide specific performance metrics or acceptance criteria for the new device itself. Information like wheelchair weight capacity (up to 425 pounds) is an "indication for use" rather than a performance criterion for a study.
- Study Details: A 510(k) submission generally relies on comparisons to predicate devices or on non-clinical (bench) testing to demonstrate substantial equivalence, rather than a clinical study with human subjects, especially for a Class I device like a manual wheelchair. The letter itself does not describe any specific study, sample sizes, ground truth, or expert involvement as typically would be found for AI/software devices requiring detailed performance evaluation.
- AI/Software-Specific Information: Questions 5, 6, 8, and 9 are highly specific to AI/software performance studies (MRMC, standalone algorithm, training set size, etc.). The Merlexi Craft Bariatric series of manual wheelchairs is a mechanical device, and these types of studies are not applicable.
Therefore, I cannot populate the table or answer the specific questions based on the provided text. The document serves a different regulatory purpose than detailing performance study results.

Manual Wheelchair (A006)
The A006 Manual Wheelchair is to provide mobility to persons limited to a sitting position.
The subject device 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.
This document describes the FDA's clearance of a Manual Wheelchair (Model A006) and is a 510(k) Premarket Notification. The purpose of a 510(k) submission is to demonstrate that a new device is "substantially equivalent" to a legally marketed predicate device. This process differs significantly from studies that prove a medical device, especially AI/ML-driven software, meets specific performance acceptance criteria through clinical or non-clinical trials.
Therefore, the provided text does not contain the information required to answer the prompt. It is a regulatory clearance document for a mechanical device, not a study evaluating the performance of an AI/ML device against acceptance criteria.
Here's why the prompt cannot be answered with this document:
- No AI/ML device: The device in question is a manual wheelchair, a physical, mechanical product. There is no software, AI, or algorithm involved.
- No "acceptance criteria" in the AI/ML performance sense: The "acceptance criteria" here refer to meeting regulatory standards for safety and effectiveness in comparison to a predicate mechanical device (another wheelchair), not to the performance metrics (like accuracy, sensitivity, specificity, AUC) typically established for AI/ML devices.
- No "study" in the AI/ML performance sense: The document describes non-clinical performance testing against established ISO standards for wheelchairs (e.g., static stability, brake effectiveness, dimensions, strength). It explicitly states, "No clinical study is included in this submission." There are no human readers, ground truth establishment, training sets, test sets, or MRMC studies as would be relevant for an AI/ML device.
To answer the prompt, a document describing the development and validation of an AI/ML-driven medical device, including performance data from a clinical or non-clinical study, would be necessary.

Manual Wheelchair
The Manual Wheelchair is intended for medical purposes to provide mobility to persons restricted to a sitting position.
The Manual Wheelchair is a wheeled personal mobility device that incorporates a seat-support system for a person with a disability or a person without the full capacity to walk designed to be manually propelled by the user while seated in the device or by an attendant. The occupant moves the wheelchair by rotating two handrims protruding from rear wheels. An attendant moves the device by pushing or pulling handles on the device. The device can be folded for transport. The device can be operated indoor or outdoor on dry, smooth surfaces composed of concrete, blacktop or asphalt under normal driving conditions. The subject manual wheelchair is a mechanical wheelchair with four wheels, including two front casters and two rear wheels, a frame made of carbon steel, a seat and a backrest made of oxford fabric, which is soft and water-resistant, two handles, armrests, handrims, foot pedals, legrest strap and seat belt. The subject manual wheelchair has a physical dimension of 1085mm × 700mm ×935mm (length × width × height). The device has a weight capacity of 100 kilograms, and its total mass is 17.3kg. The color is black.
This document describes the premarket notification (510(k)) for a Manual Wheelchair (Model: SYIV100-RLD-G01) seeking clearance from the U.S. Food and Drug Administration (FDA).
It's important to note that this is a Class I medical device (Mechanical Wheelchair, Product Code: IOR), which are generally considered low risk and do not require extensive clinical trials or complex AI performance criteria as seen with higher-class devices. The primary method for proving substantial equivalence for such devices is often through non-clinical performance testing and comparison to an existing predicate device.
Therefore, many of the typical "AI device" specific questions (like MRMC studies, training set details, or expert consensus for ground truth) are not applicable to this specific submission, as the device is not an AI-powered diagnostic or therapeutic tool. The "acceptance criteria" here refer to the device meeting established performance standards for manual wheelchairs, rather than AI performance metrics.

RoughRider Aurora Manual Wheelchair
The RoughRider America™ RoughRider Aurora™ Manual Wheelchair is indicated to provide mobility to persons restricted to a seated position up to a weight capacity of up to 250 lb / 114 kg.
The RoughRider America™ RoughRider Aurora™ Manual Wheelchair (Aurora) is a user propelled, manually operated folding wheelchair. The Aurora is designed for everyday use and to help its rider move around easily, safely, and without the restrictions imposed by much of the terrain encounter in daily life. The Aurora is expected to perform well:
- Indoors and outdoors; ●
- Over smooth, rough, and uneven ground; ●
- Over soft and hard surfaces; ●
- Over small obstacles, like door jams; and ●
- Up, down and across slopes. ●
The Aurora utilizes primarily aluminum tubing that is bent, fastened, and/or welded to create a frame. The frame is comprised primarily of side frame, X-brace, foot rest, and caster fork subassemblies. Upholstery is made from fire-resistance fabric. The rear wheels of the Aurora can be removed making the wheelchair lighter for lifting or carrying.
The side frames have three axle holes that allow the rear wheel position to be adjusted forward and backward. Wheel position affects the rider's forward and backward stability by changing wheel axle position relative to the person's center of gravity. The position of the rear wheel relative to the rider's center of gravity also affects the amount of the rider's weight that is distributed onto the front casters, and allows the rider to maximize maneuverability and control.
The Aurora side frame fenders act as fixed arm rests and enable transferring in and out of the wheelchair. The side frame also includes the backrest tubes and push handles. The backrest tubes can be adjusted up and down to meet basic support requirements of the rider and/or their companion. Wheel locks attach to the side frame and prevent the rear wheels from turning. The locks keep the wheels from moving during transfers or when a stationary position is necessary.
An X-Brace connects the side frames of the wheelchair together, determines the chair width, and allows the frame to fold. With the X-Brace in the unfolded position, the chair performs much like a typical X-Brace folding wheelchair. The Aurora can be easily folded for stowage or storage and fits easily into the cargo carrying areas of most vehicles.
The seat upholstery fastens to the top surface of each X-brace seat tube and provides support for the rider to sit. The angled, sling-style seat and tension-adjustable back fabric offers seating suitable for many different riders. The tilted seat helps keep the rider slightly reclined to reduce the chances of tipping forward and out of the chair. The back fabric can be adjusted to increase or reduce back fabric tension. The seat width of the Aurora is determined by the size of the x
brace and the seat fabric and fixed at the point of fabrication, based on the customer order. The seat can be used with a range of wheelchair and flotation (pressure relief) cushions.
The footrests are not easily removable and support the rider's lower legs or feet. The footrests are independently adjustable up and down to position the rider's legs appropriately. The footrests are hinged and can be folded up to enable easier transfers into and out of the Aurora. When the Aurora is unfolded, and the rider is sitting in the chair, the footrest design can give the rider added protection for their toes from doors or other obstacles.
The casters include the caster wheels (hubs and tires) and a caster fork. The caster is mounted to the front of the side frame using the caster barrel. The casters can turn freely 360°. The casters of the Aurora are positioned approximately five inches further forward than most hospital- or boxstyle wheelchair designs. This additional distance gives the rider of the Aurora a stable ride, in terms of forward stability.
To prevent unintended changes to the chair configuration and reduce risk to the rider, most adjustment (footrest and backrest height) require access to basic tools.
The maximum weight capacity of the chair is 250 lb (114kg).
The Aurora is based on and substantially equivalent to the established and tested design, of the Whirlwind RoughRider. This design has been refined with input from thousands of wheelchair riders around the world after over 15 years of use. The Aurora is easy to clean and uses a range of standardized components that are easy to maintain and replace.
The provided text is a 510(k) Summary for a manual wheelchair, the "RoughRider America™ RoughRider Aurora™ Manual Wheelchair." It primarily focuses on demonstrating substantial equivalence to a predicate device, the "Whirlwind RoughRider Wheelchair," by comparing technological characteristics and presenting performance data based on recognized consensus standards.

2. Sample Size Used for the Test Set and the Data Provenance
For a physical device like a wheelchair, "test set" typically refers to the number of physical units subjected to testing, rather than a dataset of clinical images. The document does not specify the number of wheelchair units tested. The data provenance is implied to be from laboratory testing conducted by the manufacturer or a contracted testing facility, as per the mentioned ISO standards. It is not clinical data (retrospective or prospective).
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
This question is not applicable to the validation of a physical manual wheelchair. "Ground truth" in this context would be derived from physical measurements and mechanical stress tests according to standardized protocols, not expert clinical interpretation.
4. Adjudication Method for the Test Set
This question is not applicable. The "tests" here are standardized engineering and mechanical performance tests, not subjective interpretations requiring adjudication.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
This question is not applicable. The device is a manual wheelchair, not an AI or imaging diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This question is not applicable as the device is not an algorithm. The "standalone performance" of the wheelchair refers to its ability to meet the stated ISO standards and functional specifications independently.
7. The Type of Ground Truth Used
For this medical device, the "ground truth" is established by:
- Standardized Test Protocols: The specific methodologies and measurements defined within the cited ISO 7176 series standards.
- Physical Measurements and Mechanical Performance: Quantitative outcomes from these standardized tests, such as stability angles, dimensions, mass, and resistance to force (fatigue, impact).
- Material Properties: Verification that the aluminum frame meets material strength and durability specifications to support increased weight capacity.
8. The Sample Size for the Training Set
This question is not applicable. There is no "training set" in the context of validating a physical manual wheelchair. The design refinements over 15 years, informed by "thousands of wheelchair riders around the world," represent an iterative design and improvement process, but not an algorithmic training set.
9. How the Ground Truth for the Training Set was Established
Not applicable, as there is no training set as defined for an AI device. The design evolution was based on real-world use and feedback, leading to refinements in features like the adjustable backrest and material choice (aluminum for lighter weight and higher capacity).

Manual Wheelchair (Model W28)
The W28 Manual Wheelchair is to provide mobility to persons limited to a sitting position.
A mechanical wheelchair is a chair with wheels, designed to be a replacement for walking, where it is propelled by the seated occupant turning the rear wheels by hand. There are also handles behind the seat for someone else to do the pushing. Wheelchairs are used by people for whom walking is difficult or impossible due to illness, injury, or disability. The device is intended for adults only.
W28 is a mechanical wheelchair including four wheels, a steel frame cover black paint and a textilene upholstery that is flame resistant. W28 has a physical dimension of 1100mm × 908mm (depth × width × height) with the seat itself has a dimension of 415mm × 500mm × 475mm (depth × height). The device has a weight capacity of 136 kilograms, and weighs about 20.5 kilograms. The color is dark black.

The provided text describes the regulatory clearance for the "Manual Wheelchair (Model W28)" and its substantial equivalence to a predicate device. It does not describe an AI/ML powered medical device, an acceptance criteria table related to AI model performance, or a study to prove an AI model meets acceptance criteria.
Therefore, I cannot provide the requested information regarding acceptance criteria and a study proving an AI device meets those criteria based on the provided document. The document details the physical characteristics, performance standards, and biocompatibility of a manual wheelchair.
However, I can extract the acceptance criteria and study information related to the manual wheelchair's physical and performance aspects if that is what you intended. Please clarify if you are interested in the acceptance criteria and performance study for the manual wheelchair itself, rather than an AI/ML device.
