The provided document describes the FDA 510(k) submission for the Detachable Silicone Balloon (DSB) Artificial Embolization Device. The submission focuses on establishing substantial equivalence to predicate devices rather than presenting a performance study with acceptance criteria in the typical sense of a clinical trial for AI/software devices. Therefore, much of the requested information regarding acceptance criteria, sample sizes, expert involvement, and ground truth for an AI-like device is not applicable to this 1998 medical device submission.
Here's a breakdown based on the available information:
1. Table of Acceptance Criteria and Reported Device Performance
The device testing mentioned in the document is primarily bench testing and biocompatibility testing, not performance metrics based on clinical outcomes relevant to AI. Acceptance criteria are implied by successful completion of these tests to demonstrate safety and functional validity for its intended use and substantial equivalence to predicate devices. Specific quantitative acceptance criteria or reported device performance in a clinical context were not provided in detail.
| Criteria Category | Details from Document | Performance Demonstrated |
|---|---|---|
| Biocompatibility | Performed | Safe for intended use |
| Functional Bench Testing (implied acceptance: successful operation) | Cycle testing | Safe for intended use |
| Rupture testing | Safe for intended use | |
| Pressure volume testing | Safe for intended use | |
| Detachment force testing | Safe for intended use | |
| Inflation-deflation cycle rate testing | Safe for intended use | |
| Catheter insertion valve testing | Safe for intended use |
2. Sample Size for the Test Set and Data Provenance
Not applicable. The submission describes bench testing and biocompatibility testing, not a clinical study with a "test set" of patient data in the context of an AI device.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable. This is not a study involving expert review of images or data for ground truth establishment.
4. Adjudication Method for the Test Set

The Patient Return Electrode is indicated for use only with Target Therapeutics GDC System as the patient return electrode.
Target Therapeutics' Patient Return Electrode (PRE) is a single use, disposable, non-sterile electrode. The PRE is intended to be used as an alternative patient return electrode for Target Therapeutics GDC system (K951256 & K960705). A hypodermic needle is currently used as the patient return electrode. The PRE is applied to the skin on the patient's upper arm (deltoid). The PRE is being made available for patient comfort and has no effect on the safety or efficacy of the GDC system as functional testing indicates.
A small Prep pad is included with the PRE to exfoliate the skin prior to applying the PRE.
This is a 510(k) premarket notification for a medical device (Patient Return Electrode). This type of submission generally does not contain detailed studies with acceptance criteria, sample sizes, expert ground truth, or MRMC studies as would be expected for AI/ML device evaluations. The focus of a 510(k) is to demonstrate substantial equivalence to a predicate device.
Therefore, many of the requested fields cannot be directly answered from the provided text. I will extract the information that is available and note when information is not present.
Here's a breakdown based on your request:
1. A table of acceptance criteria and the reported device performance
Based on the provided text, specific quantitative acceptance criteria and their corresponding reported device performance values (like sensitivity, specificity, AUC) are not explicitly stated as they would be for an AI/ML device. The document mentions "functional testing" and "bench testing" but does not provide specific metrics or thresholds.
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Safety and Efficacy (no adverse effect on GDC system) | "has no effect on the safety or efficacy of the GDC system as functional testing indicates." |
| Substantial Equivalence to predicate devices | "supports the substantial equivalence claims of the PRE for its intended use." |
| Performance in bench testing (Tensile Test, Impedance Test) | "Results of the bench testing...effectively demonstrate the PRE is substantially equivalent to the predicate devices." |
| Performance in animal studies | "Results of the...animal studies...effectively demonstrate the PRE is substantially equivalent to the predicate devices." |
| Biocompatibility | "Results of the...biocompatibility testing...effectively demonstrate the PRE is substantially equivalent to the predicate devices." |
2. Sample size used for the test set and the data provenance
- Sample size for the test set: Not specified. The document mentions "bench testing," "animal studies," and "biocompatibility testing" but does not give sample sizes for these tests.
- Data provenance: Not specified. (e.g., country of origin, retrospective/prospective).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Number of experts: Not applicable/Not specified. For this type of device (Patient Return Electrode), ground truth is established through physical/electrical measurements and biological responses, not expert interpretation of data.
- Qualifications of experts: Not applicable/Not specified.
4. Adjudication method for the test set
- Adjudication method: Not applicable/Not specified. Adjudication methods like 2+1 or 3+1 are typically used when human interpretation of data (e.g., medical images) is involved in establishing ground truth. This is not pertinent to the evaluation of a Patient Return Electrode.
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
- MRMC study: No. An MRMC study is relevant for AI/ML diagnostic devices where human readers interpret medical images or data. This is not applicable to a Patient Return Electrode.
- Effect size of human reader improvement: Not applicable.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Standalone performance: Not applicable in the context of AI/ML algorithms. The device itself (Patient Return Electrode) is a standalone component; its performance is evaluated in direct physical/electrical tests and biological studies, not as an algorithm.
7. The type of ground truth used
For this device, the "ground truth" would be established by:
- Physical/Electrical measurements: For the Tensile Test and Impedance Test, ground truth is based on engineering specifications and physics.
- Biological responses: For animal studies and biocompatibility testing, ground truth is based on observed physiological reactions and histological analyses against established safety standards.
8. The sample size for the training set
- Sample size for the training set: Not applicable. This document does not describe the development or evaluation of an AI/ML algorithm, so there is no concept of a "training set" in the sense of machine learning.
9. How the ground truth for the training set was established
- How ground truth was established for the training set: Not applicable (as there is no training set for an AI/ML algorithm).

The provided text describes a medical device (Berenstein Coil) and its equivalence to predicate devices, but it does not contain information about acceptance criteria or a study proving that a device meets specific performance criteria as typically understood in the context of AI/ML or diagnostic device performance.
The document is a 510(k) summary for a Class III medical device (Berenstein Coil). It focuses on demonstrating "substantial equivalence" to existing predicate devices, rather than establishing specific diagnostic performance metrics (like sensitivity, specificity, AUC) against a defined ground truth.
Therefore, I cannot provide a response based on your requested structure, as the necessary information regarding acceptance criteria, reported device performance, sample sizes, expert ground truth establishment, MRMC studies, standalone performance, or training set details is not present in the provided text.
The "Testing in Support of Substantial Equivalence Determination" section describes:
- In-vitro, in-vivo, and biocompatibility testing: These are general categories of testing to ensure safety and effectiveness comparable to predicate devices.
- Functional bench testing:
- Force required to deliver coils through catheters.
- Coil/catheter compatibility.
These are engineering/design validation tests, not clinical performance metrics against a ground truth.
In summary, the provided text does not contain the type of study data (e.g., diagnostic accuracy metrics against a ground truth, reader study results) that your request for "acceptance criteria and the study that proves the device meets the acceptance criteria" in the context of AI/ML or diagnostic devices would typically require.
