Intended Use

The Conductive Gel is intended for use with TENS (transcutaneous electrical nerve stimulation) and EMS (electric muscle stimulation) therapy. The Conductive Gel is used with external electrodes to reduce the impedance of the contact between the electrode surface and the skin.

Device Description

AI/ML Overview

Based on the provided text, a Conductive Gel (K221724) has received 510(k) clearance from the FDA. However, the document provided is a clearance letter, not a detailed study report. It states that the FDA has determined the device is substantially equivalent to legally marketed predicate devices.

This type of clearance (510(k)) generally means that the manufacturer demonstrated that their new device is as safe and effective as a legally marketed predicate device, and does not typically require the submission of a new, extensive clinical study with the kind of detailed performance data and study design requested in your prompt.

Therefore, I cannot provide the information you've requested regarding acceptance criteria, device performance tables, sample sizes, ground truth establishment, or specific study methods like MRMC studies, because this type of data is not typically included or required within a 510(k) clearance letter itself, especially for a device like a conductive gel.

The clearance letter focuses on regulatory compliance and substantial equivalence to existing devices.

To answer your prompt directly with information from this document:

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

  • Not provided in this document. The document primarily addresses regulatory clearance based on substantial equivalence, not detailed performance metrics against specific acceptance criteria.

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

  • Not provided in this document. No "test set" or study details are discussed.

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 provided in this document. No ground truth establishment is mentioned.

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

  • Not provided in this document. No adjudication method is mentioned.

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 and not provided in this document. MRMC studies are typically for diagnostic imaging devices involving reader performance, which doesn't apply to a conductive gel.

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

  • Not applicable and not provided in this document. This is not an AI/algorithm-based device.

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

  • Not provided in this document.

8. The sample size for the training set:

  • Not applicable and not provided in this document. This is not an algorithm-based device requiring a training set.

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

  • Not applicable and not provided in this document.

In summary: The provided document is a 510(k) clearance letter for a Conductive Gel, indicating that it has been deemed substantially equivalent to a predicate device. This type of regulatory submission and corresponding letter does not typically contain the detailed performance study data you are asking for. For such data, one would usually need to consult the full 510(k) submission summary or a separate publication of a performance study, if one was conducted and published.
