The provided text discusses the Affinity Fusion Oxygenator and its acceptance criteria, specifically focusing on the addition of an alternate hollow fiber supplier.

Here's an analysis of the acceptance criteria and the study that proves the device meets them:

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

Biocompatibility Testing:

*Note on "Pressure Integrity": Devices conditioned only to factors significant for leaks (per Two Proportion statistical test).

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

The document does not explicitly state the sample sizes for the test sets (number of oxygenator units tested) for design verification or biocompatibility. It also does not specify the country of origin of the data or whether the studies were retrospective or prospective. The nature of the tests (engineering performance and biocompatibility) suggests these were primarily laboratory-based prospective tests.

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 information is not applicable to the type of device and testing described. The "ground truth" for a medical device like an oxygenator is established through objective performance measurements and standardized biocompatibility tests, not subjective expert assessment as would be the case for image interpretation or diagnosis.

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

This information is not applicable. Adjudication methods like "2+1" or "3+1" are typically used in clinical studies or studies involving subjective human interpretation (e.g., radiology reads) to resolve discrepancies. The tests described here are objective performance and safety tests.

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 is not applicable. The device is an oxygenator, not an AI-powered diagnostic tool requiring human reader studies.

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

This is not applicable. The device is an oxygenator, not an algorithm.

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

The ground truth for this device is based on:

• Engineering specifications and standards: For performance characteristics like O2 Transfer, CO2 Transfer, Pressure Drop, Burst, Filtration Efficiency, etc. "PASS" implies meeting predefined, objective measurable criteria.
• International standards for biocompatibility (ISO 10993-1:2018): For tests like cytotoxicity, sensitization, genotoxicity, hemocompatibility, etc. "PASS" means meeting the established safety thresholds for these biological endpoints.

8. The sample size for the training set:

This is not applicable. This is not an AI/machine learning device that requires a training set. The "study" described is a series of laboratory-based design verification and biocompatibility tests.

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

This is not applicable, as there is no training set for this type of device.

The Luer cap 1140008-503 that is the 'subject' of this special 510(k) serve as protection of the Luer Access Port. This port can be used to prime the circuit or connect to another support device with a luer connector.

This is a 510(k) summary for a medical device change, not a study proving device meets acceptance criteria. Here's a breakdown of why and what information is provided:

This document describes a "Special 510(k) submission" for a change in a small component (a luer cap) within an already cleared medical device (Affinity NT Oxygenator). It is not a standalone study proving the device meets general acceptance criteria for a new device. The purpose of this submission is to demonstrate that the change to the luer cap does not adversely affect the safety and effectiveness of the previously cleared device, maintaining substantial equivalence to the predicate.

Therefore, most of the requested information (sample sizes, expert consensus, MRMC studies, etc.) is not applicable or not provided in the context of this specific regulatory submission.

Here's how to address the prompt based on the provided text:

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

The document doesn't explicitly define acceptance criteria in a quantitative table form for the overall device's performance. Instead, it focuses on demonstrating that the change to the luer cap does not negatively impact the device's functionality. The "acceptance criteria" for this specific change are implicitly tied to maintaining the original device's performance and safety.

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

• Test Set Sample Size: Not explicitly stated for specific tests related to the luer cap change. The document mentions "Risk-based testing and evaluations," suggesting a sample size appropriate for these specific tests, but the number is not provided.
• Data Provenance: Not specified. Given it's a regulatory submission by Medtronic, it's presumably internal testing conducted to support the change.

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 is a technical validation of a component change, not an evaluation requiring expert clinical interpretation for ground truth.

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

Not applicable. This is not a study requiring adjudication of 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-enabled device or an MRMC study.

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

Not applicable. This is not an algorithm-only device.

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

For the luer cap change, the "ground truth" is established through engineering and biological testing:

• Biocompatibility: Conformance to ISO 10993-1:2018 standards, which involves specific chemical and biological tests. The "ground truth" here is the pass/fail result based on laboratory analysis against these standards, leveraged from a previous clearance (K240534) for a higher-risk product.
• Functionality: Direct measurements and observations (dimensional comparison, torque removal, pressure integrity) against established engineering specifications.

8. The sample size for the training set

Not applicable. This is not a machine learning or AI device that requires a training set.

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

Not applicable.

The provided text is a 510(k) Summary for the Medtronic Affinity Fusion Oxygenator System. This document focuses on demonstrating substantial equivalence to a predicate device rather than presenting a standalone study with detailed acceptance criteria and performance data for a novel device. Therefore, much of the requested information about a specific study proving the device meets acceptance criteria is not explicitly provided in this type of regulatory submission.

However, I can extract the relevant information that is available and clarify what is not present.

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state quantitative acceptance criteria in a table format for performance metrics relevant to an "AI system" or "medical device performance" in the general sense, as typically sought in such a request. Instead, it refers to "predetermined requirements" and "improved bond performance" for specific components.

The "performance" referred to in this document primarily relates to the device meeting its intended function as an oxygenator and arterial filter during cardiopulmonary bypass. The summary states that "Operation and performance qualification... were completed" and that "the manufacturing process consistently produces product that meets predetermined requirements."

2. Sample Size Used for the Test Set and Data Provenance

The document does not specify a "test set" in the context of an AI/algorithm evaluation. For the physical device modifications, it mentions "random sampling and statistical modeling" for the TMA seal, but no specific sample sizes or data provenance (country, retrospective/prospective) are provided for these manufacturing/design evaluations.

3. Number of Experts Used to Establish Ground Truth and Qualifications

This information is not applicable to the provided document. The submission pertains to modifications of a physical medical device (oxygenator) and its manufacturing process, not to an AI/algorithm that requires expert-established ground truth from a dataset.

4. Adjudication Method

This information is not applicable to the provided document, as it does not describe an AI/algorithm evaluation requiring adjudication of ground truth.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

This information is not applicable to the provided document. The submission is for a physical medical device and does not involve AI assistance to human readers.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

This information is not applicable to the provided document. The submission is for a physical medical device and does not involve an AI algorithm.

7. Type of Ground Truth Used

This information is not applicable in the context of an AI/algorithm. For the physical device, the "ground truth" or verification is based on engineering specifications, performance testing (pressure integrity, burst, torque, insertion depth), and biocompatibility standards (ISO 10993).

8. Sample Size for the Training Set

This information is not applicable to the provided document, as it does not describe an AI/algorithm that would require a training set.

9. How the Ground Truth for the Training Set Was Established

This information is not applicable to the provided document, as it does not describe an AI/algorithm.

Summary of what the document does provide:

The document describes a 510(k) premarket notification for the Affinity Fusion Oxygenator System, which involves modifications to a legally marketed predicate device (K203111). The core of the submission is to demonstrate substantial equivalence to this predicate device.

The study presented is not a classic "clinical trial" or "AI validation study" but rather a series of engineering and qualification tests to ensure that the modifications (specifically, changes to the Temperature Monitoring Adapter (TMA) insert component material and insertion depth, and different bioactive surfaces) do not alter the fundamental performance, safety, or efficacy of the device.

Key points from the document regarding "proof" and "acceptance":

• Proof of Meeting Acceptance Criteria: The proof is based on "Operation and performance qualification (OQ/PQ)" and "Design Characterization" activities. These activities evaluate various physical properties and manufacturing consistency.
• Acceptance Criteria (Implied): The implied acceptance criteria are that the modified device's performance (e.g., pressure integrity, burst, torque, insertion depth, biocompatibility) meets internal predetermined requirements and does not introduce new hazards compared to the predicate device. For example, the TMA bond evaluation "indicated improved bond performance relative to the current material," suggesting a performance target was met or exceeded. Biocompatibility was accepted based on the new material already being used in another cleared device and conforming to ISO 10993.
• Study Design: The study is a non-clinical engineering and bench testing evaluation rather than a clinical trial or AI performance study. It's focused on validating the impact of specific component changes.
• Conclusion: The manufacturer concluded, and the FDA agreed by clearing the device, that these modifications maintain substantial equivalence to the predicate device, meaning it is as safe and effective as a device already on the market.

AFFINITY Proximal Tibia System is intended to treat fractures, nonunions of the proximal tibia including simple, comminuted, lateral wedge, depression, medial wedge, bicondylar combination of lateral wedge and depression, periprosthetic, and fractures with associated shaft fractures.

• · Simple metaphyseal fractures (Classification AO 41-A2)
• · Multifragmentary metaphyseal fractures (Classification AO 41-A3)
• · Simple bicondylar fractures (Classification AO41-C1, 41-C2)
• Multifragmentary bicondylar fractures (Classification AO 41-C3)
• · Simple joint, simple metaphyseal fractures (Classification AO 41-C1)
• · Diaphisary fractures (Classification AO 42A and 42B)

AFFINITY Proximal Tibia System consists of anatomical plates and screws for the placement of the proximal tibial condyles, improving the restoration of the original structure. Similarly, in combination with the variable angle technique, it allows for the placement of screws in different configurations providing appropriate support for the correct healing of fractures.
AFFINITY Proximal Tibia System consists of pre-contoured bone fixation plates and screws. The plates are made from biocompatible commercially pure titanium grade 4 according to ISO 5832-2 and ASTM F67 standard. The screws are made from biocompatible titanium alloy (Ti6Al4V) according to ISO 5832-3 and ASTM F136 standard.
The AFFINITY Proximal Tibia System plates can be fixed with variable angle technique.

The provided text is an FDA 510(k) summary for the AFFINITY Proximal Tibia System. This document describes a medical device (a bone plate and screw system for tibial fractures) and its claim of substantial equivalence to existing predicate devices.

Crucially, the document states that "Clinical testing was not necessary for the substantial equivalence determination." This means that the device's acceptance criteria and the proof it meets them do NOT involve human clinical studies or AI-driven performance metrics such as accuracy, sensitivity, specificity, or human-in-the-loop improvements.

Therefore, I cannot fulfill the request to describe the acceptance criteria and study that proves the device meets the acceptance criteria in the context of AI/machine learning performance. The provided text details non-clinical performance testing for a medical implant, focusing on mechanical, biocompatibility, and sterilization aspects.

Here's why I cannot provide the requested information based on the given text:

• No AI or algorithm present: There is no mention of any AI component, algorithm, or software in the device description or its testing.
• No clinical performance data (e.g., accuracy, sensitivity): The document explicitly states "Clinical testing was not necessary." The performance testing described is mechanical (bend, torsion, pullout strength), biocompatibility, and sterilization, which are relevant for physical implants, not AI diagnostic or assistive devices.
• No human reader studies (MRMC): Since no AI is involved, there are no studies assessing how human readers improve with AI assistance.
• No ground truth establishment for diagnostic performance: The "ground truth" mentioned in your prompt (expert consensus, pathology, outcomes data) is typically for validating diagnostic or classification algorithms. For a bone plate, ground truth relates to its mechanical integrity and biological safety, which were assessed through laboratory tests.

In summary, the provided document describes the regulatory approval of a physical medical device (a bone plate and screw system) through established non-clinical testing and comparison to predicates, not the validation of an AI/ML medical device.

If you have a document describing an AI/ML medical device's performance study, I would be happy to analyze it according to your detailed criteria.

Affinity is a software application used to process, display, analyse and manage nuclear medicine and other medical imaging data transferred from other workstations, PACS or acquisition stations. The information acquired from viewing the images is used, in conjunction with other patient related data, for diagnosis and monitoring of disease.

This application is not intended to replace visual assessment of tumors. The primary purpose of the application is to provide pre-selection of lesions for visual confirmation and to provide consistency and reproducibility when assessing tumor response to treatment.

Affinity can process data as whole body or constrained field of view (e.g. abdomen, brain) where scanning was performed with any of the following modalities PET/CT, MR or tomographic reconstructed SPECT/CT. The studies are read in DICOM format and if there are studies with different modalities, on the same patient, a co-registration and alignment is performed.

Software output - After the studies have been processed, these are presented visually in 2D or 3D for the user who can use tools to quantify the significant parameters SUV, SUVR, SUVbsa, SUVIbm, SUVbw, SUV Peak, SUV Mean, TLG and MTV.

Here's a breakdown of the acceptance criteria and study information for the Affinity device, based on the provided document:

Acceptance Criteria and Device Performance

Study Details

1. Sample Sizes and Data Provenance

• Test Set (for Split tool intra/inter-variability): 13 subjects (7 males, 6 females) who received F18FDG-PET/CT studies.
• Data Provenance: Not explicitly stated (e.g., country of origin). The study states "13 subjects... that received a F18FDG-PET/CT study," implying prospective data collection for this specific validation, but this is not explicitly confirmed.
• Test Set (for Hottest Connected SUV peak value accuracy): A single synthetic software-generated study containing 8 voxels.
• Data Provenance: Synthetic (software-generated).

2. Number of Experts and their Qualifications for Ground Truth

• For Split tool intra/inter-variability: No experts were used to establish ground truth in the traditional sense. The validation focused on the reproducibility of the tool itself when used by validators.
• For Hottest Connected SUV peak value accuracy: The "ground truth" was established by manual calculation. No specific number or qualifications of human experts were mentioned for this manual calculation in the provided text.

3. Adjudication Method for the Test Set

• For Split tool intra/inter-variability: Two validators repeated the process 5 times each. The variability between these repeat measurements and between the two validators was assessed. This is not a classic adjudication method for ground truth, but rather a reproducibility assessment.
• For Hottest Connected SUV peak value accuracy: Direct comparison to manual calculation. No adjudication method involving multiple human readers was described.

4. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

• No, an MRMC comparative effectiveness study involving human readers improving with AI vs. without AI assistance was not conducted or reported in the provided text. The studies focused on the performance characteristics of specific software features.

5. Standalone Performance Study

• Split tool intra/inter-variability: Yes, the study assesses the standalone reproducibility of the "threshold/split tool" by having two validators use the tool on patient data.
• Hottest Connected SUV peak value accuracy: Yes, the study assesses the standalone accuracy of the "Hottest Connected SUV peak value" by comparing its output to manual calculations.

6. Type of Ground Truth Used

• For Split tool intra/inter-variability: The "ground truth" for this test was the assumption that the tool should produce consistent quantitative values. The study measured the reproducibility of these measurements rather than comparing them to a separate, external ground truth like pathology. The process involved defining regions based on a predefined threshold, splitting them, and then deleting specific anatomical regions (brain, heart, urinary bladder) and ensuring pathological areas connected to non-pathological ones were deleted based on clinical importance. This implies an implicit clinical understanding, but not a formally established "ground truth" for each specific lesion.
• For Hottest Connected SUV peak value accuracy: Manual calculation on a synthetic dataset. This serves as the "truth" against which the algorithm's output is compared.

7. Sample Size for the Training Set

• The document does not specify a sample size for the training set. The descriptions provided relate to verification and validation testing, not model training.

8. How the Ground Truth for the Training Set Was Established

• Since no information on a training set was provided, the method for establishing its ground truth is also not available in the document.

AFFINITY is a software application used to process, display, and manage nuclear medicine and other medical imaging data transferred from other workstations, PACS or acquisition stations. The information acquired from viewing the images is used, in conjunction with other patient related data, for diagnosis and monitoring of disease.

The Affinity v1.0 is a Viewer that will be the first Hermes application released on the new development platform Affinity.

The application provides 2D and 3D visualization and processing of medical images in Digital Imaging and Communications in Medicine (DICOM) format from different modalities, such as PET/CT, MR and tomographic reconstructed SPECT from SPECT/CT. Affinity supports coregistration, with the exception of 2D images, and fusion of multiple time points with studies in the same frame of reference, different tracers, and modalities.

Affinity is developed with Microsoft Visual Studio on the .NET framework environment and designed for high throughput clinical scenarios with fast image loading and configurable workflows and layouts. In the design, emphasis has been placed on ease of use, where the user can easily access tools for 3D ROI and uptake analysis. The application supports pre-selection and automatic detection of all uptake areas within the body above a certain threshold level, by using threshold region tool. Where the user can define a threshold for any modality and unit within that modality to include all pixels of the study in a region or islands of regions.

Based on selected regions, quantification of the following parameters can be done SUV, SUVR, SUVbsa, SUVlbm, SUVbw, SUV Peak, SUV Mean, TLG and MTV.
