Intended Use

The LSC offers electrically powered seated and standing mobility to users with ambulatory impairments, including people with spinal cord injury, spina bifida, cerebral palsy, multiple sclerosis, muscular dystrophy, polio, rheumatism, etc.

Device Description

The LSC is a powered standup wheelchair. It is propelled and steered by varying the speed of the two back wheels. Front castors support the front of the caain and allow indirect steering through the turning back wheels. An electric lineanan anot system puts the seat into a seating or standing position.

AI/ML Overview

The provided document describes the LSC device, a powered standup wheelchair, and its substantial equivalence to predicate devices. However, it does not contain information about acceptance criteria and a study proving the device meets those criteria in the way typically expected for an AI/ML medical device submission.

This document is a 510(k) summary for a physical medical device (a wheelchair). The Acceptance Criteria and Study sections below are tailored to what is presented in the document regarding the device's conformity to standards and safety/effectiveness, rather than AI-specific performance metrics.

Here's the information extracted and interpreted based on the provided text:

1. A table of acceptance criteria and the reported device performance

For the LSC powered standup wheelchair, the "acceptance criteria" are the specific requirements and test methods outlined in various EN and ISO standards for wheelchairs. The "reported device performance" is the successful completion of tests according to these standards, as stated: "To approve the performance of the LSC, tests according to current applicable standards where performed at test-laboratories of European notified bodies."

Acceptance Criteria (Standard & Requirement)Reported Device Performance
EN 12182: 1999 - Technical aids for disabled persons. General requirements and test methodsTests performed according to standard
EN 12184: 1999 - Electrically powered wheelchairs, scooters and their chargers - requirements and test methodsTests performed according to standard
ISO 7176-1: 1999 - Wheelchairs. Determination of static stabilityTests performed according to standard
ISO 7176-2: 2001 - Wheelchairs. Determination of dynamic stability of electric wheelchairsTests performed according to standard
ISO 7176-3: 1988 - Wheelchairs. Determination of effectiveness of brakesTests performed according to standard
ISO 7176-4: 1997 - Wheelchairs. Energy consumption of electric wheelchairs and scooters for theoretical distanceTests performed according to standard
ISO 7176-5: 1986 - Wheelchair tests. Methods for determination of overall dimensions, mass and turning spaceTests performed according to standard
ISO 7176-6: 2001 - Wheelchairs. Determination of maximum speed, acceleration and decelerationTests performed according to standard
ISO 7176-7: 1998 - Wheelchairs. Measurement of seating and wheel dimensionTests performed according to standard
ISO 7176-8: 1998 - Wheelchairs. Requirements and test methods for static, impact and fatigue strengthTests performed according to standard
ISO 7176-9: 2001 - Wheelchairs. Climatic test for electric wheelchairsTests performed according to standard
ISO 7176-10: 1988 - Wheelchairs. Determination of obstacle-climbing ability of electric wheelchairsTests performed according to standard
ISO 7176-14: 1997 - Power and Control systems for electric wheelchairs – Requirements and test methodsTests performed according to standard
ISO 7176-15: 1996 - Wheelchairs. Requirements for information disclosure, documentation and labelingTests performed according to standard
ISO 7176-16: 1997 - Wheelchairs - Part 16: Resistance to ignition of upholstered partsTests performed according to standard
ISO 7176-20: 2001 - Wheelchairs. Determination of the performance of stand-up type wheelchairsTests performed according to standard
ISO 7176-21: 2003 - Wheelchairs. Requirements and test methods for electromagnetic compatibilityTests performed according to standard

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

This information is not explicitly detailed in the provided 510(k) summary for each specific test mentioned. For physical devices, compliance with standards often involves testing a specific number of units from a production batch, rather than data sets in the AI/ML context. The tests were performed "at test-laboratories of European notified bodies," implying European provenance. The nature of these tests (e.g., fatigue, stability, brake effectiveness) suggests a controlled laboratory environment.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This is not applicable to the type of device and testing described. The "ground truth" here is objective physical measurements and adherence to engineering and safety standards, performed by qualified personnel at accredited test laboratories, not by medical experts establishing diagnostic ground truth.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. The tests are based on objective performance metrics against established standards, not on expert consensus or adjudication of subjective data.

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

Not applicable. This is a physical medical device (wheelchair), not an AI/ML diagnostic or assistive tool for human readers. No MRMC study was performed.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

Not applicable. This is a physical device, not an algorithm.

7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)

The "ground truth" for this device's performance is adherence to established international and European standards (EN and ISO) for wheelchairs, which involve objective physical measurements, mechanical stress tests, electrical component tests, and biological safety evaluations.

8. The sample size for the training set

Not applicable. This is a physical medical device, not an AI/ML algorithm that requires a training set.

9. How the ground truth for the training set was established

Not applicable. As above, this is a physical medical device and does not involve a training set or corresponding ground truth establishment in the AI/ML sense.

Dear Ms. Bankston:

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. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
