Intended Use

The intended use of the Pride Mobility Products Corporation Victory Four Wheel Scooter, is to provide mobility to persons having limited walking capabilities.

Device Description

The Victory Four Wheel Scooter is a mid-size battery-operated scooter having a programmable 70-amp Digital Controller. Features include a removable molded plastic seat, a foldable tiller, and an off board charger. Additional safety features include electronic regenerative and electromechanical disc brakes, and rear anti-tip wheels. The Victory Four Wheel Scooter is designed for, but not limited to Pride Mobility Products Corp. providers / retailers and their consumers.

The Victory Four Wheel Scooter is designed with ultimate safety, stability, performance, and portability in mind. The main feature of the Scooter is a narrow wheelbase (22"), which allows better maneuverability from a mid-sized product.

AI/ML Overview

The provided text describes the regulatory submission for the "Victory Four Wheel Scooter" and primarily focuses on its substantial equivalence to a predicate device, the Pride Mobility SC340 (K930952). The content does not describe a study that involves acceptance criteria, device performance, sample sizes, ground truth from experts, or comparative effectiveness studies in the context of AI/algorithm performance.

Instead, the document details non-clinical testing for compliance with established standards for wheelchairs and scooters. Since the request specifically asks for information related to AI/algorithm performance studies, and this document pertains to a physical medical device (a scooter) and its regulatory approval based on non-clinical testing and predicate device comparison, most of the requested information is not applicable.

Here's a breakdown based on the provided text, highlighting where information is N/A (Not Applicable) or not provided.


Acceptance Criteria and Device Performance (Not Applicable for AI/Algorithm Study)

The document lists compliance with various testing standards for the physical scooter. These are "acceptance criteria" in the sense of regulatory compliance for a physical device, but not in the context of an AI/algorithm performance study.

Table of Acceptance Criteria and Reported Device Performance:

Acceptance Criteria CategorySpecific Standard/RequirementReported Device Performance / Compliance Status
Non-Clinical TestingANSI/RESNA WC Vol. 1-1998Compliant
ANSI/RESNA WC Vol. 2-1998Compliant
ANSI/RESNA WC Vol. 2-1998 Section 21 (Electromagnetic Compatibility)Compliant
IEC 60335-2-29 (Battery Chargers)Compliant
IEC 601-1-1 (Electrical Medical Equipment Safety)Compliant
CAL 117 (Flammability Testing)Compliant
Substantial EquivalenceComparison to Predicate Device (Pride Mobility SC340, K930952)Considered substantially equivalent based on similar intended use, technological characteristics, components, performance, maneuverability, stability, and structure. Differences (wheelbase, frame construction, control mechanisms) do not raise new safety/effectiveness questions.

Study Details (Not Applicable for AI/Algorithm Study)

This section is largely N/A as the document explicitly states "N/A" for "Discussion of Clinical Testing Performed" and focuses on non-clinical engineering and design compliance.

  1. Sample size used for the test set and the data provenance:

    • N/A. This device is a physical scooter, not an AI/algorithm. Test sets, in the context of AI, are not relevant here. The "testing" involved physical product performance against engineering standards.
    • Data provenance: N/A.
  2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

    • N/A. Ground truth, in the context of expert review for AI, is not applicable. Regulatory compliance is assessed by adherence to established engineering standards, presumably by qualified engineers/testers.
  3. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

    • N/A. Adjudication methods for expert consensus on ground truth are not applicable to non-clinical engineering tests.
  4. 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:

    • N/A. This is a physical device, not an AI solution designed to "assist human readers."
  5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

    • N/A. This is a physical product, not an algorithm.
  6. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

    • N/A (in the AI sense). For this device, "ground truth" would be compliance with objective engineering specifications and safety standards (e.g., a specific torque, speed, stability angle, or flammability resistance measured during testing).
  7. The sample size for the training set:

    • N/A. No AI training set is involved.
  8. How the ground truth for the training set was established:

    • N/A. No AI training set is involved.
