Conclusion: The non-clinical performance data demonstrated that the subject devices, when exposed to the MR environment under specific MR conditions of use, did not raise new questions of safety or efficacy.
2. Sample Size Used for the Test Set and the Data Provenance
The document does not detail a "test set" in the context of clinical or algorithmic performance. The testing described is non-clinical performance testing on the devices themselves to assess their safety in an MR environment. Therefore, information about human data provenance, sample size of a test set, etc., is not applicable to this type of study.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
Not Applicable. As this is non-clinical performance testing for MR safety, there is no "test set" that requires expert ground truth establishment in the traditional sense of medical image analysis or diagnosis. The "ground truth" here is the physical interaction of the device with the MR environment as measured by standardized tests.
4. Adjudication Method for the Test Set
Not Applicable. There is no "test set" requiring adjudication by experts. The performance is measured against established engineering standards for MR safety.
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 describes non-clinical performance testing for MR safety of physical implants and wires. It does not involve any AI, human readers, or a comparative effectiveness study.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done
No. The document describes non-clinical performance testing of physical medical devices, not an algorithm.
7. The Type of Ground Truth Used

CFR 888.3030 (HRS, Plate, Fixation, Bone)
21 CFR 888.3040 (HWC, Screw, Fixation, Bone)
21 CFR 878.4495
The Thorecon Rigid Fixation System is intended for use in the stabilization of fractures of the anterior chest wall including sternal fixation following sternotomy and sternal reconstructive surgical procedures. The system is intended for use in patients with normal and/or poor bone quality.
The Thorecon Rigid Fixation System may be implanted via an open or minimally invasive approach. Where additional stability is desired, devices can be used with traditional monofilament wire or Sternal Cable of similar material. The Thorecon Rigid Fixation System includes plates (some with integrated cable subassemblies) manufactured from 316L stainless steel (ASTM F138) and screws comprised of 22Cr-13Ni-5Mn stainless steel (ASTM F1314). Non-implantable needles, used to guide the cable around the sternum, are manufactured from 420 or Custom 470 stainless steel. Thorecon devices are all single-use. The plates, complete with the necessary screws and instruments (torque driver and tensioner/cutter) required for completion of the surgery, are provided sterile in a disposable kit. Sterile instruments and screw multi-packs and a non-sterile cable/ plate cutter instrument are also available as replacements and for use during emergent re-entry, if necessary. The devices should be implanted using only the manual surgical instruments designed specifically for the implants in the system.
The provided text is a 510(k) Premarket Notification for the Thorecon™ Rigid Fixation System. It describes a medical device related to bone fixation, specifically for the sternum. The document focuses on regulatory approval and substantial equivalence to a predicate device, supported by non-clinical (mechanical and MR safety) testing.
Therefore, the information requested about acceptance criteria, study design for AI/human reader performance, sample sizes for training/test sets, expert ground truth establishment, adjudication methods, and MRMC studies is not present in this document. This document concerns a physical medical device (implants, screws, etc.) and its mechanical and material properties, not an AI or software-as-a-medical-device (SaMD) product.
The document states:
- Purpose of Submission: To obtain clearance of modifications to the Thorecon Rigid Fixation System, including the addition of MR Conditional Safety Labeling.
- Discussion of Supporting Non-Clinical Testing: "The following nonclinical tests were submitted and relied on in this premarket notification submission for a determination of substantial equivalence. Testing identified in this summary has all passed acceptance criteria established by the predicate device where applicable."
- Mechanical Performance (Worst-Case Construct Assessment, Assessment of previously completed testing, Cerclage Dynamic Tension Testing)
- MR Safety Evaluation following standards (ASTM F2052-15, ASTM F2213-17, ASTM F2182-11a, ASTM F2119-07)
Since the request is specifically about a study that proves a device meets acceptance criteria, and the provided text is about a physical medical device (Thorecon™ Rigid Fixation System) rather than a software or AI device, it's important to clarify that the "device" in question here is the implantable hardware.
Here's an interpretation of the acceptance criteria and the study based on the provided document, in the context of a physical medical device, while acknowledging that the original prompt's questions are generally geared towards AI/SaMD.
Acceptance Criteria and Device Performance (for a Physical Medical Device)
The document does not explicitly list quantitative acceptance criteria in a table format with reported performance for individual tests. Instead, it states that all identified nonclinical tests "passed acceptance criteria established by the predicate device where applicable." This indicates a qualitative statement of compliance rather than specific numerical values.
1. Table of Acceptance Criteria and Reported Device Performance
Based on the document, this exact table cannot be constructed with specific numerical values as they are not provided.
Acceptance Criterion (Type of Test) | Basis for Acceptance | Reported Device Performance |
---|---|---|
Mechanical Performance | Substantial equivalence to predicate device (K173579 Thorecon Fixation System). Passed acceptance criteria established by predicate. | Passed |
Worst-Case Construct Assessment | Acceptable performance as compared to predicate. | Passed |
Cerclage Dynamic Tension Testing | Acceptable performance as compared to predicate. | Passed |
MR Safety Evaluation | Compliance with ASTM standards and FDA Guidance "Establishing Safety and Compatibility of Passive Implants in the Magnetic Resonance (MR) Environment", December 11, 2014. | Device determined to be MR Conditional based on results of testing. |
Magnetically Induced Displacement Force (ASTM F2052-15) | Met standard | Passed |
Magnetically Induced Torque (ASTM F2213-17) | Met standard | Passed |
Radio Frequency Induced Heating (ASTM F2182-11a) | Met standard | Passed |
MR Image Artifacts (ASTM F2119-07) | Met standard | Passed |
2. Sample Size Used for the Test Set and the Data Provenance
For a physical device's mechanical and MR safety testing:
- Sample Size: Not explicitly stated as "sample size" in the context of human data. For mechanical and MR safety testing of physical devices, samples would refer to the number of device units tested. This specific number is not provided in the summary.
- Data Provenance: This is not applicable in the context of human data or geographical origin for mechanical and MR safety testing of a physical device. These tests are laboratory-based.
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 mechanical and MR safety testing of a physical medical device is established by physical measurements and compliance with engineering standards, not by expert human interpretation.
4. Adjudication Method for the Test Set
Not applicable. This applies to subjective human interpretations for ground truth, not objective physical 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
Not applicable. This is for AI-assisted image interpretation or similar cognitive tasks, not for a physical implantable device.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is for AI algorithms, not a physical implantable device.
7. The Type of Ground Truth Used
- For Mechanical Performance: Engineering specifications, material properties, and comparative performance against the predicate device.
- For MR Safety Evaluation: Compliance with established ASTM standards (F2052-15, F2213-17, F2182-11a, F2119-07) and FDA guidance for MR conditional labeling.
8. The Sample Size for the Training Set
Not applicable. This terminology refers to machine learning models. For a physical device, there isn't a "training set" in the AI sense. Design and manufacturing processes are iteratively refined based on engineering principles and test results.
9. How the Ground Truth for the Training Set Was Established
Not applicable. As above, this is for AI models. Principles of engineering and materials science guide the design and manufacturing of the device.
Summary in relation to the document:
The provided document, a 510(k) Premarket Notification, is for a physical medical device (Thorecon™ Rigid Fixation System) which aids in sternal fixation. The "study that proves the device meets the acceptance criteria" in this context refers to non-clinical bench testing for mechanical performance and MR compatibility. The document states that these tests were conducted and "passed acceptance criteria established by the predicate device where applicable" and complied with relevant ASTM standards and FDA guidance for MR safety, leading to the "MR Conditional" designation.
The questions in the prompt are largely tailored for Artificial Intelligence (AI) or Software as a Medical Device (SaMD) products, which typically involve performance evaluation based on human-interpreted data, often medical images. The nature of the Thorecon™ Rigid Fixation System and the testing described in this 510(k) summary (mechanical and MR safety) does not involve AI or human data interpretation studies of the kind implied by the questions.

The devices should be implanted using only the manual surgical instruments designed specifically for the implants in the system.
Here is an analysis of the acceptance criteria and supporting study for the Thorecon™ Fixation System, based on the provided text:
Preamble: The provided document is a 510(k) summary for a medical device (Thorecon™ Fixation System), which focuses on demonstrating substantial equivalence to predicate devices rather than proving novel effectiveness. Therefore, the "study" referenced in the context of this document primarily refers to non-clinical testing performed to show that the new device performs at least as safely and effectively as existing, legally marketed devices. It is not an effectiveness study in the typical sense of a clinical trial demonstrating a new treatment's efficacy.
Acceptance Criteria and Reported Device Performance
Acceptance Criteria Category | Reported Device Performance (Summary of Study Results) |
---|---|
Mechanical Performance | Passed Acceptance Criteria Established by Predicate Devices or Test Standards. Specific tests included: |
- Screw Push-Out of Plate Force Test
- Bone Screw Pull-Out Test per ASTM F543
- Static Tension Testing
- Dynamic Tension Testing |
| Packaging, Sterility & Shelf Life | Validation completed per standards: - ISO 11607 (Packaging)
- ASTM D4169 (Shipping Containers)
- ISO 11137-2 (Sterilization Dose)
- ASTM F1980 (Accelerated Aging)
- ISO 17665-1 (Moist Heat Sterilization) |
| Biocompatibility | Evaluation completed per ISO 10993 (Parts 1, 5, 10, and 11). |
| Pyrogenicity | Evaluated using Limulus amebocyte lysate (LAL) assay, ensuring endotoxin level meets the requirement of maximum endotoxin limit for implantable medical devices [20 EU per device]. |
Additional Information on the "Study" (Non-Clinical Testing)
-
Sample Size Used for the Test Set and Data Provenance:
- The document does not specify numerical sample sizes for the individual mechanical, packaging, sterility, shelf life, biocompatibility, or pyrogenicity tests. It only states that these tests were performed and "passed acceptance criteria."
- The data provenance is internal, originating from testing conducted by or for A&E Medical Corporation to support their 510(k) submission. No specific country of origin for the data is mentioned, but the company is based in the USA. The tests are non-clinical (laboratory/bench) studies, not patient data (retrospective or prospective).
-
Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:
- This question is not applicable in the context of this 510(k) submission. "Ground truth" and "experts" are terms typically used in studies involving subjective assessments (e.g., image interpretation, clinical diagnosis) where human judgment needs to be standardized or measured against a gold standard. For engineering and materials testing (mechanical performance, sterility, etc.), the "ground truth" is defined by established scientific principles, validated testing methodologies, and international standards (e.g., ISO, ASTM), rather than expert consensus on subjective observations.
-
Adjudication Method for the Test Set:
- This is not applicable as the "test set" consists of non-clinical, objective measurements against pre-defined performance standards or predicate device performance, not subjective appraisals requiring adjudication.
-
If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done:
- No, an MRMC comparative effectiveness study was not done. This type of study typically involves human readers (e.g., radiologists) interpreting medical images or clinical data, often with and without AI assistance, to assess diagnostic performance. The Thorecon™ Fixation System is a surgical implant; its performance is evaluated through biomechanical and materials testing, not through diagnostic interpretation.
-
If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done:
- This question is not applicable as the Thorecon™ Fixation System is a physical medical device (surgical implant), not an algorithm or AI software. Therefore, there is no "standalone" algorithm performance to evaluate.
-
The Type of Ground Truth Used:
- The "ground truth" for the non-clinical tests mentioned (mechanical, packaging, sterility, biocompatibility, pyrogenicity) is based on established industry standards (e.g., ASTM, ISO), regulatory requirements (e.g., FDA guidelines), and performance data from predicate devices. For example, for mechanical tests, the ground truth is a specific force or displacement value that the device must withstand or perform to a certain degree. For pyrogenicity, it's a defined endotoxin limit. For biocompatibility, it's compliance with established biological safety profiles.
-
The Sample Size for the Training Set:
- This question is not applicable. "Training set" refers to data used to train machine learning models. The Thorecon™ Fixation System is a physical medical device, not an AI software, and therefore does not have a "training set" in this context. The manufacturing process and design are based on engineering principles and material science, not machine learning.
-
How the Ground Truth for the Training Set Was Established:
- This question is not applicable for the same reason as point 7.

Trade/Device Name: Stainless Steel Suture Regulation Number: 21 CFR 878.4495
| 21 CFR 878.4495
Regulation | 21 CFR 878.4495
marketed, by Ethicon, Inc. class II device with FDA product code (GAQ), regulatory definition (21 CFR 878.4495
Stainless Steel Suture is indicated for use in abdominal wound closure, hernia repair, sternal closure and orthopaedic procedures including cerclage and tendon repair.
Stainless Steel Suture is a sterile monofilament or multifilament, non-absorbable sterile surgical suture composed of 316L stainless steel. The suture is also available coated with polyethylene. Stainless Steel Suture is available in a range of gauge sizes and lengths, non-needled or attached to needles of various types and sizes. Stainless Steel Suture complies with the requirements of the European Pharmacopoeia (Ph. Eur.) for Sterile Non-Absorbable Strands and the United States Pharmacopoeia (USP) for Non Absorbable Surgical Sutures. The European Pharmacopoeia recognizes units of measure Metric and Ph. Eur. sizes as equivalent which is reflected on the labeling.
Stainless Steel Suture elicits a minimal acute inflammatory reaction in tissue and is not absorbed. Implantation studies in animals show that no significant change in the retention of tensile strength of the suture occurs during the lifetime of the implantation.
The provided text describes a 510(k) premarket notification for a medical device called "Stainless Steel Suture" by Ethicon Incorporated. This is not a study proving device performance against acceptance criteria in the manner typically seen for new, innovative devices with novel performance characteristics or AI components. Instead, it's a submission to demonstrate substantial equivalence to a legally marketed predicate device.
Therefore, many of the requested categories (like sample sizes for test/training sets, number of experts, adjudication methods, MRMC studies, standalone performance of an algorithm, and ground truth types related to performance metrics) are not applicable in this context because the FDA cleared this device based on its substantial equivalence to an existing device, rather than novel performance data from a clinical or algorithm-based study.
The primary "acceptance criteria" here relate to demonstrating that the new device is as safe and effective as the predicate device, with a focus on updated labeling for MRI safety. The "study" isn't a complex clinical trial or AI algorithm validation, but rather a series of bench and design verification tests and a comparison to the predicate.
Here's the information extracted and adapted to the prompt, with explanations for why certain fields are not applicable:
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria Category | Specific Criteria (Target) | Reported Device Performance |

2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: Not explicitly stated as this was a substantial equivalence submission based on bench testing of the product, not a clinical study with patient data. The tests would have used appropriate numbers of suture samples per the relevant ASTM and USP standards.
- Data Provenance: The data provenance is from bench/design verification activities performed by Ethicon Inc., in compliance with design control requirements. The data is prospective in the sense that these tests were conducted specifically for this 510(k) submission on the device to verify compliance with standards and MRI safety guidelines. Country of origin not specified, but likely where Ethicon's primary R&D/manufacturing takes place (e.g., USA given the submitter's address).
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of those Experts
- Not Applicable. For a device like a stainless steel suture cleared via substantial equivalence, ground truth as typically defined for AI or diagnostic studies (i.e., expert consensus on clinical findings, pathology confirmation) is not relevant. The "ground truth" for the bench tests would be the established scientific/engineering principles and the specifications within the referenced ASTM and USP standards. The "experts" involved are the testing personnel and engineers who conducted and validated the bench tests according to recognized industry standards.
4. Adjudication Method for the Test Set
- Not Applicable. Adjudication methods (like 2+1 or 3+1 consensus) are typically used in clinical studies or AI algorithm validation to resolve discrepancies among human readers or between AI and human reads. This submission is based on objective bench testing against pre-defined engineering and safety standards, not subjective interpretations requiring adjudication.
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 device is a surgical suture, not an AI-powered diagnostic or assistive tool. Therefore, no MRMC study involving human readers or AI assistance was conducted or is relevant for its clearance.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
- Not Applicable. This device is a physical surgical implant, not an algorithm or software. No standalone algorithm performance testing was performed.
7. The Type of Ground Truth Used
- Engineering Standards and Specifications: The "ground truth" for this device's performance is compliance with established and recognized engineering and medical device standards, specifically:
- United States Pharmacopoeia (USP) monographs for sutures ( Needle Attachment, Tensile Strength, Diameter).
- ASTM Standards for MRI Safety (F2503, F2052, F2119, F2182, F2213).
- AAMI/ANSI/ISO 10993-7 for EO residual testing.
- ANSI/AAMI ST72:2011 and USP , for Bacterial Endotoxin Testing (BET).
- European Pharmacopoeia (Ph. Eur.) for Sterile Non-Absorbable Strands.
- The "ground truth" also stems from the long history of safe and effective use of the predicate device (Surgical Stainless Steel Suture, K946173) which the proposed device is substantially equivalent to.
8. The Sample Size for the Training Set
- Not Applicable. This is not an AI/machine learning device, 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 for an AI algorithm, this question is not relevant.
