Here's an analysis of the provided text regarding acceptance criteria and the study conducted for the Revolve Envi 600 Advanced Adipose System:
This document is a 510(k) summary for a medical device (Revolve Envi 600 Advanced Adipose System). As such, it reports on studies performed to demonstrate substantial equivalence to a predicate device, rather than a clinical trial demonstrating efficacy of a novel device. Therefore, many of the typical elements of an AI-specific study focusing on metrics like sensitivity, specificity, and reader performance are not applicable or not reported in this type of submission. The 'acceptance criteria' in this context refer to engineering and performance benchmarks for the device itself, rather than diagnostic performance metrics.
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria (Bench Testing / Evaluation) | Reported Device Performance |

- Data Provenance: Not applicable in the context of clinical data for a diagnostic device. The data are from laboratory bench testing of the physical medical device and its components, in-house or by contracted labs.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- Not Applicable. This device is a mechanical system for processing adipose tissue, not an AI or diagnostic device requiring expert interpretation for "ground truth" establishment in a diagnostic context. The "ground truth" here is the physical performance of the device and biological response to its materials.
4. Adjudication Method for the Test Set
- Not Applicable. As there are no human interpretations or diagnostic outcomes to adjudicate, this concept does not apply to the provided study summary.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs Without AI Assistance
- No, an MRMC study was not done. This is a review of a device for processing adipose tissue, not an AI-assisted diagnostic tool. Therefore, such a study is not relevant to this submission.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done
- Not Applicable. This device does not involve an algorithm or AI. It is a physical medical device.
7. The Type of Ground Truth Used

Summary of the Study:
The provided document describes a 510(k) premarket notification for the Revolve Envi 600 Advanced Adipose System. The "study" refers to a series of bench tests and biocompatibility assessments designed to demonstrate the device's safety and effectiveness and its substantial equivalence to a legally marketed predicate device (Revolve™ System, K120902).
The core of the "study" is:
- Biocompatibility Testing: According to ISO 10993-1 and FDA guidance, classifying the device as an "Externally Communicating Device, Tissue, Limited Contact (≤24 hours)". It passed tests for cytotoxicity, sensitization, irritation, acute systemic toxicity, and material-mediated pyrogenicity.
- Sterilization Validation: Demonstrated a Sterility Assurance Level (SAL) of 10⁻⁵ through gamma irradiation, validated per ISO 11137-2:2013.
- Bench Testing: Included evaluation of adipose tissue viability (via Lactate Dehydrogenase assessment) and simulated use testing covering device stability, leakage, processing time, functionality under vacuum, and tubing connection tensile strength. These tests were performed on both the subject and predicate devices to show comparability.
Crucially, no clinical testing was included in this submission, and this is explicitly stated. The acceptance criteria are engineering and biological safety standards for a mechanical medical device, rather than diagnostic performance metrics (like sensitivity/specificity) typical for AI or imaging devices. Environmental or operational conditions are tested, but not in a 'diagnostic accuracy' sense.

ARTIA Tissue Matrix is intended for use as a soft tissue patch to reinforce soft tissue where weakness exists and for the surgical repair of damaged or ruptured soft tissue membranes which require or bridging material to obtain the desired surgical outcome. The implant is intended for reinforcement in plastic and reconstructive surgery.
ARTIA Tissue Matrix is intended for single patient, one time use only.
ARTIA Reconstructive Tissue Matrix Perforated (ARTIA Tissue Matrix Perforated) is a surgical mesh that is derived from porcine dermis and is processed and preserved in a patented phosphate buffered aqueous solution containing matrix stabilizers. ARTIA Tissue Matrix Perforated is designed to perform as a surgical mesh for soft tissue repair while presenting a scaffold for cellular and microvascular ingrowth. ARTIA Tissue Matrix Perforated consists of a terminally sterilized sheet of processed porcine dermal matrix provided in various geometric configurations and packaged in a plastic holder enclosed within a pouch. The device is sterilized via electron beam irradiation. The subject device has the same underlying scientific technology, principles of operation, Intended Use and Indications for Use as the cleared predicate device, ARTIA Tissue Matrix (K142326). This 510(k) premarket notification describes a new design feature of the subject device, which introduces a 3mm diameter circular pattern of perforations (holes) throughout the tissue matrix.
I am sorry, but the provided text does not contain the detailed information necessary to complete the requested table and answer all the questions regarding acceptance criteria and a study proving device performance as it relates to an AI/ML device.
The document is a 510(k) premarket notification for a medical device called ARTIA Reconstructive Tissue Matrix Perforated, which is a surgical mesh. This process establishes substantial equivalence to a predicate device, not necessarily a study demonstrating the device meets specific acceptance criteria in the manner one would for an AI/ML product's performance metrics.
Specifically, the document discusses bench testing for the surgical mesh to demonstrate substantial equivalence to a predicate device, not clinical performance or AI/ML algorithm performance.
Here's a breakdown of why the information is not available in the provided text:
- No AI/ML Device: The device described (ARTIA Reconstructive Tissue Matrix Perforated) is a surgical mesh, not an AI/ML-driven medical device. Therefore, questions related to AI/ML performance, training sets, and expert adjudication are not applicable.
- No Acceptance Criteria for AI/ML Performance: The acceptance criteria mentioned are for mechanical properties of a surgical mesh (e.g., mesh thickness, tensile strength, burst strength), not for AI/ML algorithm outputs like sensitivity, specificity, or accuracy.
- No Performance Data in the Requested Format: While the document states that "Performance data demonstrates that ARTIA Tissue Matrix Perforated has similar mechanical properties and meets the established specifications as the predicate device," it does not provide the specific numerical results or a direct comparison table as requested for an AI/ML device.
- No Clinical Study for Effectiveness: The document explicitly states: "Clinical Testing: No clinical testing was included in this submission." This means there is no study establishing clinical effectiveness or comparative performance with human readers.
- No Ground Truth: The concept of "ground truth" as it applies to AI/ML model training and evaluation (e.g., pathology, expert consensus on imaging) is not relevant for a surgical mesh. The "ground truth" for the mesh would be its physical and chemical properties, which are evaluated by bench tests.
- No Training/Test Sets: As this is not an AI/ML device, the concepts of training sets and test sets for algorithm development and evaluation are not applicable.
Therefore, I cannot fulfill your request based on the provided text. The information requested pertains to the evaluation of AI/ML-driven medical devices, while the provided document describes a traditional surgical mesh device.

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample Size: Not specified for the bench tests.
- Data Provenance: Not applicable as this is bench testing on materials, not human data. There is no mention of country of origin.
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. This document describes bench testing of a physical medical device, not an AI or diagnostic device requiring expert interpretation for ground truth.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. There is no human interpretation or adjudication involved in the described bench testing.
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. The document explicitly states: "No clinical testing was included in this submission." This is a 510(k) submission for a surgical mesh, not a diagnostic AI device, so such a study would not be expected or relevant here.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is not an algorithm or AI device. The "device" is a physical surgical mesh.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
Not applicable. For the bench tests, the "ground truth" would be the measured physical properties of the material, compared to established material standards (like ASTM or ISO) or the predicate device.
8. The sample size for the training set
Not applicable. This is not an AI or algorithm device requiring a training set.
9. How the ground truth for the training set was established
Not applicable.
