    AI/ML Overview

    The provided text describes a 510(k) premarket notification for the "Pressure Therapy System PT1003". This document focuses on demonstrating substantial equivalence to predicate devices rather than proving a predetermined set of acceptance criteria for a novel AI/imaging device. As such, many of the requested categories for AI/imaging device studies (like MRMC studies, effect size of AI assistance, expert qualifications, sample provenance, training sets, etc.) are not applicable or not provided in this regulatory submission.

    However, I can extract information related to the performance characteristics, safety testing, and how the device's adherence to standards and safety was demonstrated.

    Here's a breakdown of the available information:

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

    The document doesn't explicitly state "acceptance criteria" in the format typically used for AI/imaging performance metrics (e.g., sensitivity, specificity, AUC). Instead, it demonstrates compliance with recognized medical device standards and functional tests to ensure safety and performance comparable to legally marketed predicate devices.

    Acceptance Criteria (Implied from testing)Reported Device Performance (PT1003)
    Electrical Safety (AAMI ANSI ES 60601-1:2005/(R)2012 and A1:2012, C1:2009/(R)2012 and A2:2010/(R)2012)Met the standard.
    Electromagnetic Compatibility (IEC 60601-1-2 Edition 3: 2007-03)Met the standard.
    Home Healthcare Environment Safety (IEC 60601-1-11 Edition 2.0 2015-01)Met the standard.
    Biocompatibility - Cytotoxicity (ISO10993-5)Met the standard.
    Biocompatibility - Irritation & Skin Sensitization (ISO 10993-10)Met the standard.
    Minimum and Maximum Air PressureTested as defined, result "almost same" as predicate. Max pressure 200 mmHg, Min pressure 20 mmHg.
    Maximum Electric Current ValueTested as defined, result "almost same" as predicate.
    Maximum Airflow ValueTested as defined, result "almost same" as predicate.
    Noise LevelTested as defined, result "almost same" as predicate.
    Modes A and B functionalityTested as defined, result "almost same" as predicate.
    Pressure Range Comparator (compared to K182668)Max Pressure of 200mmHg is within the safe range established by predicate K182668 (0-200mmHg).
    Indications for Use EquivalenceIdentical to predicate K183169 ("to temporarily relieve minor muscle aches and/or pains, and to temporarily increase circulation to the treated areas").

    2. Sample size used for the test set and the data provenance

    This document does not describe a test set in the context of clinical data for AI/imaging performance. The testing performed consists of bench testing and electrical/biocompatibility safety evaluations on the device itself. Therefore, concepts like "sample size" for a data set or "data provenance" (country of origin, retrospective/prospective) are not applicable. The tests were performed on the "PT1003" device following defined procedures.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

    Not applicable. "Ground truth" for AI/imaging interpretation is not relevant for this type of device (a powered inflatable tube massager). The evaluation focuses on engineering, safety, and functional performance.

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

    Not applicable. This is not a study requiring adjudication of expert interpretations.

    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 not an AI/imaging device.

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

    Not applicable. This is not an AI/imaging device. The "standalone" performance here refers to the device's functional and safety performance in isolation, which was indeed assessed through the listed standards and function tests.

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

    The "ground truth" for this device's evaluation is primarily established by regulatory standards (e.g., IEC, ISO, AAMI ANSI ES) and the functional and safety performance of legally marketed predicate devices. The device is deemed safe and effective if it meets these standards and its performance characteristics (like pressure range, cycle time) are comparable to or safely within the established parameters of already cleared devices.

    8. The sample size for the training set

    Not applicable. This is not an AI/imaging device, and therefore does not involve a "training set" in the machine learning sense.

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

    Not applicable. As above, no training set for AI was used.

    Intended Use

    The device is indicated for use by medical professionals and patient at home, who are under medical supervision, in treating many conditions, such as: Primary lymph edema following trauma and sport injuries, Post immobilization edema, Venous insufficiencies, Lymph edema.

    Device Description

    The system consists of an air pump, leg sleeves and hoses working together as one unit. The air pump is connected to the dedicated sleeves via a series of hoses; one sleeve has 4 compression chambers.

    AI/ML Overview

    The provided text is a 510(k) Pre-market Notification for the "Pressure Therapy System PT1003", which seems to be a medical device. This document focuses on demonstrating substantial equivalence to a predicate device (PT1002), rather than providing detailed acceptance criteria and a study design for a new, AI-powered diagnostic device.

    Therefore, the information required to answer your specific questions about AI/ML device acceptance criteria and a study proving performance (e.g., sample size for test set, data provenance, number of experts for ground truth, MRMC study, standalone performance, training set details) is not present in the provided document.

    The document discusses:

    • Device Description: A pneumatic compression system (PT1003) for treating conditions like lymphedema and venous insufficiencies.
    • Predicate Device: PT1002, an earlier version by the same manufacturer.
    • Substantial Equivalence: The primary goal of the 510(k) submission is to show that PT1003 is substantially equivalent to PT1002 in terms of intended use, indications, and technological characteristics.
    • Minor Differences: Changes in appearance and PCB components (microprocessors, touch keys) are noted, with the manufacturer asserting these changes do not affect safety or performance.
    • Performance Characteristics: Mentions adherence to various safety standards (AAMI ANSI ES 60601-1, IEC 60601-1-2, ISO10993-5, ISO 10993-10) and general "function tests" (min/max air pressure, electric current, airflow, noise level, modes A and B). It states that test results are "almost same" as the predicate device.

    Without the specific details about AI/ML components and their performance evaluation, I cannot generate the table or answer the questions related to AI device acceptance criteria and study proving its performance.

    The document's "Performance characteristic" section is very general and does not provide:

    • Specific Acceptance Criteria (quantitative thresholds for performance metrics).
    • Detailed Study Design: e.g., how the "function tests" were conducted, the sample size of devices tested, the number of measurements taken, or the statistical methods used to compare results between PT1003 and PT1002.
    • Ground Truth Establishment: For a simple physical therapy device evaluating pressure and airflow, "ground truth" would likely be derived from calibrated measurement instruments, not expert consensus or pathology, and these details are not provided.

    In summary, the provided text describes a traditional medical device 510(k) submission, not an AI/ML powered device, and therefore lacks the information needed to answer your questions about AI device validation.

    AI/ML Overview

    The provided document is a 510(k) Premarket Notification for a medical device (Pressure Therapy System, K161907). It aims to demonstrate substantial equivalence to a predicate device, not necessarily to prove the device meets specific performance acceptance criteria through the kind of study described in your request.

    The document discusses the device's technical characteristics and how they compare to a predicate device. It also lists the standards a performance test was conducted against to demonstrate safety and effectiveness. However, it does not include the detailed type of study you're asking about (e.g., a multi-reader multi-case clinical study with performance metrics like sensitivity/specificity, specific acceptance criteria for diagnostic performance, or extensive details on ground truth establishment from a clinical dataset).

    Here's a breakdown of what the document does provide in relation to your request, and what it does not provide:


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

    • What's explicitly stated: The document lists standards that the device was tested against. This implies that meeting these standards served as "acceptance criteria" for safety and basic operational performance.
      • IEC 60601-1 (Medical electrical equipment - Part 1: General requirements for basic safety and essential performance)
      • IEC 60601-1-2 (Medical electrical equipment - Part 1-2: General requirements for basic safety and essential performance - Collateral standard: Electromagnetic compatibility - Requirements and tests)
      • ISO10993-5 (Biological evaluations of medical devices -- Part 5: Tests for In Vitro cytotoxicity)
      • ISO 10993-10 (Biological evaluation of medical devices - Part 10: Tests for irritation and skin sensitization)
    • Reported Device Performance: The document states, "The Pt1002 pressure therapy system has been tested and met the following standards." It does not provide specific performance values (e.g., specific pressure accuracy tolerances, cycle time deviations) against quantified acceptance criteria. Instead, it concludes that the device "has substantially equivalent technological and performance characteristics" to the predicate device and "is as safe and effective as the predicate device."
    • Missing from your request: There are no specific numerical acceptance criteria for diagnostic accuracy or clinical effectiveness (e.g., sensitivity, specificity for detecting a condition) because this is a physical therapy device, not a diagnostic AI.

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

    • Not Applicable/Not Provided: This document describes a submission for a physical therapy device. The testing mentioned (compliance with IEC and ISO standards) would typically involve engineering tests on the device itself and biocompatibility tests on materials, not clinical trials with "test sets" of patient data in the way an AI diagnostic device would. Therefore, sample size for a "test set" and data provenance from patient data are not detailed, as they are not relevant to this type of device submission as described.

    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)

    • Not Applicable/Not Provided: Ground truth by experts is relevant for diagnostic AI devices, clinical studies, or performance evaluations that require expert interpretation of data (e.g., images, physiological signals). For this physical therapy device, compliance with technical safety and biocompatibility standards does not involve expert-established ground truth in this manner.

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

    • Not Applicable/Not Provided: As noted, this type of submission for a physical therapy device focuses on engineering and biocompatibility standards, not the adjudication of clinical outcomes or diagnostic interpretations.

    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

    • No: This is not a diagnostic AI device, and therefore, an MRMC study is not relevant or mentioned.

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

    • Not Applicable: This is a physical therapy device, not an algorithm, so the concept of standalone performance does not apply in the context of AI without human-in-the-loop.

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

    • Not Applicable/Implicit: For the standards listed, the "ground truth" would be the defined specifications and methodologies within those standards (e.g., a specific electrical resistance value, a specific biocompatibility response under defined lab conditions). This is not "expert consensus" or "pathology" in the clinical sense.

    8. The sample size for the training set

    • Not Applicable/Not Provided: This is not an AI/machine learning device that requires a "training set" of data.

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

    • Not Applicable/Not Provided: As it's not an AI/machine learning device, the concept of establishing ground truth for a training set does not apply.

    In summary:

    This 510(k) submission for the "Pressure Therapy System" focuses on demonstrating substantial equivalence to a predicate device by comparing technical specifications and confirming compliance with recognized safety, electromagnetic compatibility, and biocompatibility standards. It does not provide the detailed performance study information with clinical acceptance criteria, test set, ground truth, or expert involvement that would be expected for a diagnostic device or an AI-powered system as detailed in your request.
