The provided text describes a 510(k) summary for the AMPLATZER® TorqVue® 2 Delivery Sheath, a medical device. This document is a regulatory submission to the FDA, and as such, it focuses on demonstrating substantial equivalence to a predicate device rather than fulfilling typical "acceptance criteria" and "studies" in the way one might expect for a novel AI/software medical device.
Therefore, many of the requested points related to AI software performance (e.g., sample sizes for test and training sets, number of experts for ground truth, MRMC studies, standalone performance, provenance of data) are not applicable to this type of device and submission.
Here's an analysis based on the information provided:
1. A table of acceptance criteria and the reported device performance
For this device, "acceptance criteria" are not reported as specific performance metrics in the same way an AI algorithm would have sensitivity/specificity thresholds. Instead, the acceptance criteria are implicitly that the device performs comparably to the predicate device across various functional and safety characteristics. The reported "performance" is that it met these criteria through bench testing.
| Acceptance Criteria (Implicit) | Reported Device Performance |
|---|---|
| Functional Equivalence to Predicate Device: Satisfy key functional characteristics similar to the AMPLATZER® TorqVue® Delivery System (K072313). | The functional characteristics of the AMPLATZER® TorqVue® 2 Delivery Sheath are substantially equivalent to the predicate device. Bench testing confirmed this. |
| Visual and Dimensional Integrity: Correct physical appearance and dimensions. | Included in "Bench testing of the AMPLATZER® TorqVue® 2 Delivery Sheath included visual and dimensional inspection." |
| Resistance to Kinking: Maintain structural integrity and patency when bent. | Included in "Bench testing of the AMPPLATZER® TorqVue® 2 Delivery Sheath included... resistance to kinking due to bending." |
| Freedom from Leakage (Air and Liquid): Prevent unintended passage of fluids or air. | Included in "Bench testing of the AMPLATZER® TorqVue® 2 Delivery Sheath included... freedom from leakage of air and liquid." |
| Tensile Strength: Sufficient mechanical strength to withstand operational forces. | Included in "Bench testing of the AMPLATZER® TorqVue® 2 Delivery Sheath included... tensile strength." |
| Device Interaction: Compatibility and proper interaction with other devices (e.g., devices passed through the sheath). | Included in "Bench testing of the AMPLATZER® TorqVue® 2 Delivery Sheath included... device interaction testing." |
| Distribution Simulation: Maintain integrity and functionality after simulated shipping/handling. | Included in "Bench testing of the AMPLATZER® TorqVue® 2 Delivery Sheath included... and distribution simulation." |
| Manufacturing Materials and Processes: Similar to predicate. | "Manufacturing materials and processes are similar" to the predicate. |
| Sterilization Method: Same as predicate. | "Sterilization method is the same" as the predicate. |
| Sterile Package Materials: Same as predicate. | "Sterile package materials are the same" as the predicate. |
| Intended Use: Consistent with the predicate device (or a subset thereof). | "Indications for Use for the TorqVue 2 Delivery Sheath are a subset of the TorqVue Delivery System." The intended use is to "provide a pathway through which devices are introduced within the peripheral vasculature," which is consistent with the general purpose of delivery sheaths. |
Study Title: Not explicitly named, but referred to as "Bench testing" and "laboratory verification test."
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample Size for Test Set: Not specified. Bench testing often involves a statistically determined number of units or replicates for each test, but the exact numbers are not detailed in this summary.
- Data Provenance: The testing appears to be internal "bench testing" and "laboratory verification tests" performed by the manufacturer, AGA Medical Corporation, in Plymouth, MN, USA.
- Retrospective/Prospective: As this is bench testing of physical properties, these terms are not applicable in the typical clinical study sense. The tests are designed and executed prospectively in a lab setting.
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 physical medical device (delivery sheath), not an AI algorithm requiring expert interpretation for "ground truth" on images or clinical data. The "ground truth" for its performance is derived from standardized engineering tests measuring physical properties.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not Applicable: As above, this is bench testing of a physical device. There is no "adjudication method" involving experts for a test set in the context of clinical interpretation or diagnosis. Test results are objective measurements against predetermined specifications.
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, not an AI algorithm. Therefore, MRMC studies are not relevant.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not Applicable: As this is a physical medical device, not an algorithm, the concept of "standalone performance" for an algorithm is not relevant.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- Ground Truth Type: For a physical device, the "ground truth" is defined by engineering specifications, industry standards, and the performance characteristics of the predicate device. For instance, the "ground truth" for tensile strength would be a defined force threshold, or for kinking, a specific angle of bend without occlusion. These are objective, measurable physical properties.
8. The sample size for the training set
- Not Applicable: This is a physical medical device. There is no "training set" in the context of machine learning or AI.
9. How the ground truth for the training set was established
- Not Applicable: As there is no training set, the establishment of ground truth for it is not relevant.

The Plug is attached to a 135 cm Delivery Wire with a stainless steel screw. The AMPLATZER® Vascular Plug II is provided contained within a Loader Device that facilitates loading into a delivery catheter. The Delivery Wire comes coiled in a hoop dispenser. The AMPLATZER® Vascular Plug II is available in fully-expanded diameters of: 3 mm to 22 mm.
The provided document is a 510(k) summary for the AMPLATZER® Vascular Plug II, which describes a medical device, not an AI/ML device. Therefore, the typical acceptance criteria and study design elements requested in the prompt, such as test sets, ground truth definitions, expert qualifications, and MRMC studies, are not applicable here.
The document primarily focuses on demonstrating substantial equivalence to a predicate device, which is the standard for 510(k) clearances.
However, I can extract the relevant information from the provided text to demonstrate the device's performance against its stated equivalence.
1. A table of acceptance criteria and the reported device performance
The "acceptance criteria" for a medical device in a 510(k) submission are typically related to demonstrating that the modified device performs as intended and is as safe and effective as the predicate device. These are generally not quantitative metrics like precision or recall, but rather tests confirming functional equivalence.
| Acceptance Criteria (Demonstrated Equivalence) | Reported Device Performance (Test Data) |
|---|---|
| Intended Use Equivalence: | The AMPLATZER® Vascular Plug II has an identical intended use to the predicate device: "arterial and venous embolizations in the peripheral vasculature." |
| Design/Material Equivalence: | Both devices are sterile, single-use, triple-lobed, self-expanding Nitinol mesh occlusion devices. Both have a screw attachment for a Delivery Wire and radiopaque marker bands. Both use identical patient-contacting materials and the same Nitinol Delivery Wire. Both come preloaded in a loader device. Both have the same operating principle. The only modification is an extended size range (3mm, 18mm, 20mm, 22mm added to 4-16mm). |
| Functional Equivalence: | "Verification and validation testing confirms that the functional characteristics of the AMPLATZER® Vascular Plug II are substantially equivalent to the predicate device cited." This included: Radial force testing, Handoff and advancement forces, Device deployment, Recapture and detachment verification, Overall strength determinations. |
| Performance Equivalence (In Vivo): | "Animal testing was also performed to validate the product under simulated conditions of use." |
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 specify a "test set" in the context of an AI/ML device. For this medical device, the "test data" refers to the studies performed to validate its functional characteristics and in vivo performance.
- Sample Size: Not explicitly quantified. For bench testing (radial force, handoff, etc.), it would depend on the specific test protocols. For animal testing, the number of animals or procedures is not disclosed in the summary.
- Data Provenance: Not specified within the provided summary. Typical for such a submission, bench testing would be conducted in a laboratory setting, and animal testing would be conducted under appropriate ethical and regulatory guidelines, likely within the US or a country with comparable standards.
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 concept is not applicable as the submission is for a medical device, not an AI/ML diagnostic or predictive tool that requires expert-established ground truth for a test set. The validation relies on engineering and biological tests demonstrating physical and functional attributes.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. There is no "test set" requiring expert adjudication as would be found in an AI/ML study.
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-assisted device, and thus no MRMC study would be performed for human reader improvement.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Not applicable. This is a physical medical device, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the verification and validation (V&V) of this device, the "ground truth" is established by:
- Engineering specifications and standards: For bench tests like radial force, deployment, and strength. The "ground truth" is adherence to predefined engineering requirements.
- Physiological and anatomical suitability: For animal testing, the "ground truth" would be successful embolization and lack of adverse events in a simulated biological environment, demonstrating the device performs its intended function in vivo without unforeseen complications.
8. The sample size for the training set
Not applicable. This is a physical medical device, not an AI/ML model, so there is no "training set."
9. How the ground truth for the training set was established
Not applicable, as there is no "training set."

The AMPLATZER® Vascular Plug II is indicated for arterial and venous embolizations in the peripheral vasculature.
The AMPLATZER® Vascular Plug II is a sterile, single-use, triple-lobed. self-expanding Nitinol mesh occlusion device, with a screwattachment for a Delivery Wire and radiopaque marker bands at both ends. The Plug is attached to a 135 cm Delivery Wire with a stainless steel screw. The AMPLATZER® Vascular Plug II is provided contained within a Loader Device that facilitates loading into a delivery catheter. The Delivery Wire is coiled and packaged in a hoop dispenser.
The AMPLATZER® Vascular Pluq II is available in fully-expanded diameters of: 4mm, 6mm, 10mm, 12mm, 14mm and 16 mm.
The provided 510(k) summary for the AMPLATZER® Vascular Plug II does not contain the level of detail regarding acceptance criteria and performance studies typically associated with AI/ML device submissions. This document describes a medical device, an embolization plug, which is a physical device, not a software algorithm. Therefore, many of the requested categories related to software performance, AI/ML models, and clinical study design (like ground truth, expert consensus, MRMC studies, large training/test sets, etc.) are not applicable or detailed in this type of submission for a physical device.
However, I will extract and synthesize the relevant information presented in the document to address as many of your points as possible, adapting the interpretation to fit the context of a physical medical device.
1. Table of Acceptance Criteria and Reported Device Performance
The document does not explicitly state quantitative "acceptance criteria" in the format typically seen with software performance metrics (e.g., sensitivity > X%, specificity > Y%). Instead, the "acceptance criteria" for this physical device are implicitly tied to demonstrating "substantial equivalence" to the predicate device through various verification and validation tests. The "reported device performance" refers to the successful completion of these tests, confirming functional equivalence.
| Acceptance Criteria (Implicit from Substantial Equivalence Claim) | Reported Device Performance (Summary of Test Data) |
|---|---|
| Functional characteristics substantially equivalent to predicate device (K031810) | - Radial force testing: Confirmed functional equivalence.- Handoff and advancement forces: Confirmed functional equivalence.- Device deployment: Confirmed functional equivalence.- Recapture and detachment verification: Confirmed functional equivalence.- Overall strength determinations: Confirmed functional equivalence. |
| Validation of product under simulated conditions of use | - Animal testing: Validated the product under simulated conditions of use. |
| Maintain identical intended uses as predicate device | - The AMPLATZER® Vascular Plug II is indicated for arterial and venous embolizations in the peripheral vasculature, identical to the predicate device. |
| Maintain same patient-contacting materials | - The AMPLATZER® Vascular Plug II has exactly the same patient-contacting materials as the predicate. |
| Maintain same Nitinol Delivery Wire | - The AMPLATZER® Vascular Plug II has the same Nitinol Delivery Wire as the predicate. |
| Maintain same operating principle | - Both devices operate on the principle of a self-expanding Nitinol mesh delivered through a catheter, expanding to occlude the vessel upon release. |
| Device modifications (shape, braid layers, loader material) do not adversely affect performance and substantial equivalence. | - Verification and validation testing (radial force, deployment, etc.) confirms the functional characteristics are substantially equivalent despite these modifications. |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: The document does not specify a numerical sample size for the "test set" in terms of cases or patients. The testing described (radial force, handoff, deployment, etc.) likely involved a number of device units or components, and animal testing would have involved a certain number of animals. However, these specific numbers are not provided.
- Data Provenance:
- Country of Origin: Not specified. Standard practice for such tests often involves in-house labs or contract research organizations, but the geographical location is not mentioned.
- Retrospective or Prospective: The testing described (radial force, deployment, animal testing) is inherently prospective. These are laboratory and in-vivo tests conducted specifically for the purpose of demonstrating device performance and safety for the 510(k) submission. They are not analyses of pre-existing clinical data.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This concept is not applicable to this type of device submission. "Ground truth" established by experts (e.g., radiologists interpreting images) is a concept relevant to AI/ML or diagnostic devices where human interpretation is being benchmarked or assisted. For a physical embolization device, the "ground truth" is determined by direct physical measurements (e.g., radial force, deployment success) and direct observation of physiological effects in animal models. No human experts are described as establishing a "ground truth" in the diagnostic sense for these tests.
4. Adjudication Method for the Test Set
This is not applicable in the context of this device and testing. Adjudication methods like 2+1 or 3+1 are used to resolve discrepancies in human interpretations or expert opinions when establishing ground truth for diagnostic accuracy studies. For physical device performance tests (e.g., radial force, deployment), results are typically objective measurements or observations, rather than subjective interpretations requiring adjudication.
5. Multi Reader Multi Case (MRMC) Comparative Effectiveness Study
- Done?: No, an MRMC comparative effectiveness study was not done or reported.
- Effect Size of Human Readers Improve with AI vs. Without AI Assistance: This question is not applicable. An MRMC study with AI assistance is specifically designed for AI/ML diagnostic or assistive devices to measure the impact of AI on human reader performance. The AMPLATZER® Vascular Plug II is a therapeutic embolization device, not an AI-powered diagnostic tool.
6. Standalone (i.e., algorithm only without human-in-the loop performance) Study
This is not applicable. The AMPLATZER® Vascular Plug II is a physical embolization device, not an algorithm. Therefore, there is no "standalone algorithm" performance to report.
7. Type of Ground Truth Used
The "ground truth" for this device's performance evaluation was based on:
- Engineering and Biomechanical Measurements: Objective measurements of physical properties (e.g., radial force, handoff force, deployment success, recapture, detachment, strength).
- In Vivo Observation: Direct observation of the device's performance and physiological interaction in animal models under simulated conditions of use. Essentially, the "truth" was whether the device performed as expected and intended in a controlled physical/biological environment.
8. Sample Size for the Training Set
This is not applicable. The concept of a "training set" refers to data used to train an AI/ML model. This device is a physical product, not an AI/ML system.
9. How the Ground Truth for the Training Set Was Established
This is not applicable for the same reasons as point 8.

The AMPLATZER® Reliant™ Catheter Delivery System is intended to provide a pathway through which diagnostic and therapeutic transvenous devices are introduced within the chambers and coronary vasculature of the heart.
The AMPLATZER® Reliant™ Catheter Delivery System is a sterile. single-use device designed to facilitate the introduction of transvenous devices within the chambers and coronary vasculature of the heart. The catheter has a single lumen for passage of transvenous devices with maximum outer diameters of 6-12 French (2.0-4.0 mm). The catheters currently come in 60 cm and 80 cm usable lengths. The system includes the following components: Delivery Catheter, Dilator, Loader, Delivery Wire, Vise, Hemostasis Valve.
The provided text describes a 510(k) premarket notification for the AMPLATZER® Reliant™ Catheter Delivery System. This is a medical device submission, and the "study" referred to here is the set of verification and validation tests conducted to demonstrate substantial equivalence to a predicate device, rather than a clinical study with human patients and outcomes data in the typical sense for a diagnostic AI device.
Here's a breakdown based on the information provided:
1. Table of Acceptance Criteria and Reported Device Performance:
The document broadly states that "Verification and validation testing confirms that the functional characteristics of the AMPLATZER® Reliant™ Catheter Delivery System are substantially equivalent to the predicate device cited. This included catheter integrity, catheter kink resistance, leak resistance, hub strength and the ability to deliver various implantable devices."
Specific numerical acceptance criteria and performance values are not provided in this summary. The 510(k) summary typically provides a high-level overview, with detailed test reports available to the FDA reviewer.
| Acceptance Criterion (Implicit) | Reported Device Performance (Implicit) |
|---|---|
| Catheter integrity | Demonstrated substantial equivalence to predicate device. |
| Catheter kink resistance | Demonstrated substantial equivalence to predicate device. |
| Leak resistance | Demonstrated substantial equivalence to predicate device. |
| Hub strength | Demonstrated substantial equivalence to predicate device. |
| Ability to deliver various implantable devices | Demonstrated substantial equivalence to predicate device. |
| Functional characteristics for intended use | Demonstrated substantial equivalence to predicate device. |
2. Sample Size Used for the Test Set and Data Provenance:
- Sample Size: The document does not specify the sample sizes for each of the "verification and validation testing" categories (catheter integrity, kink resistance, etc.). These would typically be detailed in the full test reports.
- Data Provenance: The tests are described as in vitro performance information and laboratory verification tests. This indicates the testing was conducted in a controlled lab setting, not on patient data. Therefore, there is no country of origin for patient data, nor is it retrospective or prospective in the clinical sense.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:
This concept is not applicable here. Ground truth, in the context of diagnostic AI, refers to the definitive determination of a condition (e.g., presence of disease) that the AI is trying to detect. For a physical medical device like a catheter delivery system, the "ground truth" for its performance is established through standard engineering and materials testing, adhering to recognized industry standards. The performance is measured against established physical and mechanical specifications, not expert interpretation of images or patient outcomes.
4. Adjudication Method for the Test Set:
Not applicable. Adjudication methods (like 2+1, 3+1) are used for resolving discrepancies among expert interpretations of complex data (e.g., medical images) to establish a consensus ground truth. Since the "test set" here refers to physical products undergoing engineering tests, this methodology is not relevant.
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. MRMC studies are used for evaluating the impact of diagnostic aids (like AI) on human reader performance for tasks such as image interpretation. This device is a catheter delivery system, a physical tool for introducing other devices, not a diagnostic aid that enhances human reading of cases.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done:
Not applicable. This device is a physical catheter delivery system, not a software algorithm.
7. The Type of Ground Truth Used:
As explained in point 3, the concept of "ground truth" in the diagnostic AI sense doesn't apply directly here. The "truth" for this device's performance is derived from:
- Engineering specifications and standards: The device is tested against predefined physical and mechanical properties and performance criteria (e.g., minimum tensile strength, maximum leak rate, resistance to kinking).
- Predicate device performance: The primary goal of a 510(k) is to demonstrate substantial equivalence. Therefore, the "truth" is often relative to the established performance characteristics of the legally marketed predicate device.
8. The Sample Size for the Training Set:
Not applicable. This is a physical medical device, not an AI/machine learning model that requires a training set.
9. How the Ground Truth for the Training Set Was Established:
Not applicable, for the same reasons as point 8.
