Disposable ECG Cable and Leadwires with specific various lengths are the replacements for similar cables manufactured by Original Equipment Manufacturers (OEM) and other third party after market manufacturers for their respective monitors.
These devices consist of connectors on each cable end and a shielded bulk cables are used to transfer the signals from the electrodes to the patient monitor.
These devices use the same type of constructions and have the same technological characteristics as the predicate devices. They use a medical grade PVC and TPU cable jacket with medical grade PVC and ABS over molded connectors with integral relief.
The provided text describes the regulatory clearance of a medical device, the "Med-link Disposable ECG Cable and Leadwires," but it does not contain information about a study proving the device meets acceptance criteria in the way you've outlined.
The document is a 510(k) premarket notification summary, which aims to demonstrate "substantial equivalence" to a legally marketed predicate device, rather than proving performance against specific acceptance criteria through clinical or detailed standalone studies.
Here's a breakdown of why this document doesn't fit your request and what information it does provide:
- Type of Device: The device is a Disposable ECG Cable and Leadwires, which is an accessory to ECG monitoring devices, not a diagnostic algorithm or AI system. Therefore, the concepts of "sensitivity," "specificity," "AI improvement," "training sets," "test sets," "ground truth," or "expert adjudication" as typically applied to AI/ML medical devices are not relevant here.
- Purpose of 510(k): The primary goal of a 510(k) submission is to show that a new device is "substantially equivalent" to a predicate device already on the market, meaning it has the same intended use and technological characteristics, or if there are differences, those differences do not raise new questions of safety and effectiveness.
Given this context, I cannot fill out your requested table and information points as they pertain to a different type of device evaluation (e.g., for an AI/ML diagnostic software).
However, I can extract the information that is relevant to the document provided:

ECG Cable and Leadwires Performance: ANSI/AAMI EC53:2013 (ECG Trunk Cables And Patient Leadwires) | Meets the requirements of the standard ANSI/AAMI EC53. The proposed device was tested according to EC53. The safety performances are demonstrated by the Third party, CTI through testing following ANSI AAMI EC53. The results of bench testing & type testing provide reasonable assurance that the proposed device has been designed and validated to assure conformance to the requirements for its indication for use. |
Biocompatibility: ISO 10993-1, ISO 10993-5, ISO 10993-10 (Biological evaluation of medical devices) (Specifically for material difference: ISO 10993-10 for irritation and skin sensitization) | Complied with ISO 10993-1, ISO 10993-5, ISO 10993-10. For the material difference, the proposed device was specifically tested according to ISO 10993-10. The biocompatibility performance equivalence evidence can be demonstrated. |
Shelf Life / Package Integrity: (Functional performance testing following real-time aging test) | Package integrity and functional performance testing were completed on the subject device following real time aging test to support the proposed shelf life. |
Here's why the other points you requested are not available in this document:
- Sample size used for the test set and data provenance: Not applicable. This device is an accessory (cable/leadwire) and its performance is evaluated against engineering/safety standards (IEC, AAMI, ISO), not clinical data sets with "test sets" or "data provenance" in the context of an algorithm. The testing involves bench and type testing of the physical device according to standards.
- Number of experts used to establish the ground truth... and their qualifications: Not applicable. There is no "ground truth" to establish through experts for an ECG cable's performance in the way a diagnostic algorithm requires. Compliance to standards is verified through laboratory testing.
- Adjudication method: Not applicable. No human adjudication is mentioned or relevant for electrical and biocompatibility testing of a cable.
- If a multi reader multi case (MRMC) comparative effectiveness study was done: No. This is not an AI/ML diagnostic device, so MRMC studies are irrelevant.
- If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an algorithm.
- The type of ground truth used: Not applicable. The "ground truth" here is compliance with established engineering and safety standards, verified through bench testing.
- The sample size for the training set: Not applicable. There is no "training set" for an ECG cable.
- How the ground truth for the training set was established: Not applicable.
In conclusion, the provided document details the "substantial equivalence" of an ECG cable to a predicate device by demonstrating compliance with relevant international and national standards for electrical safety, performance, and biocompatibility through non-clinical (bench and type) testing, not through a clinical study with acceptance criteria for diagnostic accuracy metrics.

Instead, the acceptance criteria and testing described are focused on device safety and performance characteristics for a physical medical device (an incontinence probe), not an AI/ML diagnostic tool.
Therefore, I cannot provide the requested information about acceptance criteria and a study proving device diagnostic performance, as the document is about a different type of device and testing.
The document covers:
- Non-clinical testing for a physical device (Incontinence Probe).
- Tests performed include: Biocompatibility (cytotoxicity, sensitization, irritation), Shelf-life validation, Electrical Safety (IEC 60601-1), and Performance Bench Testing (visual testing, electrical output verification, cable dielectric strength, lead wire contact resistance, ANSI/AAMI EC53).
- The "acceptance criteria" here are implicitly tied to the standards cited (e.g., ISO 10993 for biocompatibility, IEC 60601-1 for electrical safety, ANSI/AAMI EC53 for lead wires), meaning the device passed these standard tests as acceptable.
If the request was based on a misunderstanding of the device type, and the intent was to find information on a diagnostic AI device, this document does not contain that information.

The provenance of the data is not specified in terms of country of origin or whether the tests were retrospective or prospective. It states the tests were "conducted in accordance with" the listed standards, implying a controlled testing environment.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:
This information is not provided in the document. The non-clinical testing primarily focuses on objective measurements against international standards rather than expert-derived ground truth as might be seen in diagnostic imaging studies.
4. Adjudication Method for the Test Set:
This information is not applicable and is not provided. The testing involves standardized laboratory and performance tests, not a judgmental adjudication process.
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 information is not applicable and is not provided. The device is a blood pressure cuff, not an AI-assisted diagnostic tool for which MRMC studies would typically be conducted.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was Done:
This information is not applicable and is not provided. The device is not an algorithm, so standalone algorithm performance is not relevant. The performance of the cuff is evaluated as a physical accessory for blood pressure measurement systems.
7. The Type of Ground Truth Used:
The ground truth for the performance claims relies on:
- International Standards: Compliance with ISO 81060-1, IEC 80601-2-30, ISO 10993-5, and ISO 10993-10. These standards establish the acceptable technical performance and safety criteria for such devices.
- Biocompatibility Testing: Objective laboratory tests (cytotoxicity, skin irritation, skin sensitization) directly measure the device's interaction with biological systems against established thresholds.
- Predicate Device Comparison: The inherent assumption is that if the device performs equivalently to legally marketed predicate devices that have already met regulatory requirements, then it is safe and effective.
8. The Sample Size for the Training Set:
This information is not applicable to this type of medical device. Blood pressure cuffs are mechanical devices, and their performance is established through physical and biological testing, not machine learning models that require training sets.
9. How the Ground Truth for the Training Set was Established:
This information is not applicable for the reasons stated in item 8.

Here's an analysis of the acceptance criteria and the study that proves the device meets them:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria are primarily based on the FDA recognized consensus standard ISO 81060-1:2007/ AAMI/ANSI/ISO81060-1:2007/(R)2013 Non-Invasive Sphygmomanometers -Part 1: Requirements And Test Methods For Non-Automated Measurement Type, and ISO 10993 (Biological evaluation of medical devices) series for biocompatibility.
Acceptance Criteria Category | Specific Acceptance Criteria (Standard Reference) | Reported Device Performance (Summary) |
---|---|---|
Performance | Compliance with ISO 81060-1:2007/ AAMI/ANSI/ISO81060-1:2007/(R)2013, Part 1: Requirements And Test Methods For Non-Automated Measurement Type | "Performance testing was performed on the subject device and results were compared with predicate device. Tests were conducted following applicable procedures outlined in the FDA recognized consensus standard of AAMI/ANSI/ISO81060-1:2007/(R)2013, and results met all relevant requirements in the test standard." |
Biocompatibility | ISO 10993-1: Biological evaluation of medical devices-Part 1: Evaluation and testing | "A series of safety, essential performance and in vitro biocompatibility tests were performed... The tests listed below were conducted in accordance with ISO 10993-1, ISO 10993-5, ISO 10993-10." |
ISO 10993-5: Test for in vitro cytotoxicity | "Cytotoxicity Test" performed. Data not explicitly detailed in summary but implied to meet criteria. | |
ISO 10993-10: Tests for Irritation And Skin Sensitization | "Skin irritation Test" and "Skin Sensitization Test (the Guinea Pig maximization test)" performed. Data not explicitly detailed in summary but implied to meet criteria. | |
Pressure Limit | 0-300mmHg matching predicate devices | Proposed device has a pressure limit of "0-300mmHg," which is identical to the primary and secondary predicate devices. |
Sterility | Non-sterile matching predicate devices | Proposed device is "Non-sterile," which is identical to the primary and secondary predicate devices. |
2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the sample size used for the performance testing. It mentions "Performance testing was performed on the subject device," but does not specify the number of devices or measurements.
The data provenance is not specified regarding country of origin or specific study design (retrospective or prospective). The tests are described as "non-clinical testing," which suggests laboratory-based evaluations rather than human subject trials for the core performance and biocompatibility aspects.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
This document describes the testing of a basic medical accessory (blood pressure cuff). The "ground truth" for its performance is established by objective measurements against a recognized standard (ISO 81060-1). There is no mention of experts establishing a "ground truth" in the way one might for diagnostic imaging or a subjective clinical assessment. The ground truth for biocompatibility is established through standardized laboratory tests.
4. Adjudication Method for the Test Set
Not applicable. The performance and biocompatibility tests are objective measurements against established standards, not subjective assessments requiring adjudication by multiple experts.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No. This is a 510(k) submission for a blood pressure cuff, which is a physical accessory, not an AI or imaging-based diagnostic device. Therefore, an MRMC comparative effectiveness study, which typically evaluates human readers' performance with and without AI assistance, is not relevant or applicable here.
6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study
Not applicable. This device is a passive accessory and does not involve an algorithm. Its function is to interface with a blood pressure measurement system.
7. Type of Ground Truth Used
The ground truth used for performance testing (accuracy and reliability of pressure transmission, cuff inflation/deflation, etc.) is the adherence to the ISO 81060-1 standard's objective requirements and test methods.
For biocompatibility testing, the ground truth is established by the results of standardized laboratory tests (Cytotoxicity, Skin Irritation, Skin Sensitization) as defined by the ISO 10993 series.
8. Sample Size for the Training Set
Not applicable. This device is not an AI/machine learning algorithm and therefore does not have a "training set."
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this device.
