The Empi Action Patch Iontophoresis System is indicated for the local administration of ionic solutions into the body for medical purposes and can be used as an alternative to injections.
The Empi Action Patch Iontophoresis System is a disposable single-use iontophoresis device with a self-contained battery and electrical circuitry. A single adhesive patch unifies both the battery-powered iontophoresis device and the active and return electrodes. The Empi Action Patch is designed to deliver a calibrated and fixed dose of ionic solution (between 1 and 160 mAmp * min.) over a specified time. After delivery of the specified dose, an LED indicator light extinguishes indicating that that the Patch can be removed.
This 510(k) premarket notification for the Empi Action Patch Iontophoresis System does not contain the detailed study information regarding acceptance criteria and performance data that you've requested.
The document primarily focuses on establishing substantial equivalence to predicate devices. This means that instead of presenting new clinical performance studies against defined acceptance criteria, the manufacturer is demonstrating that their new device is as safe and effective as devices already on the market.
Therefore, for your specific request, I can only provide the following based on the provided text:
1. A table of acceptance criteria and the reported device performance
This document does not define specific quantitative "acceptance criteria" and "reported device performance" in the way one would expect from a clinical trial or performance study aiming to prove efficacy against a predefined standard. The evaluation of this device is based on its substantial equivalence to predicate devices, focusing on:
| Acceptance Criteria (Implied by Substantial Equivalence Claim) | Reported Device Performance (as claimed for Substantial Equivalence) |
|---|---|
| Intended Use Equivalence | "The Empi Action Patch has the same intended use as the above identified predicate devices... it is intended to be used for the local administration of ionic solutions into the body for medical purposes and as an alternative to injections." |
| Technological Characteristics Equivalence | "Like the Birch Point IontoPatch, the Empi Action Patch is a disposable, self-contained, single use iontophoresis device in a unified patch form. In terms of outward appearance and intended use, it is substantially equivalent to the IontoPatch." |
| "Both incorporate a battery to supply current to the electrodes and a means of electronically controlling a fixed dose (current * time)." | |
| Output voltage: Action Patch produces 10.5 volts (vs. IontoPatch 1 volt, Dupel 60 volts). This is presented as an "intrinsic safety factor." | |
| "The Empi Action Patch uses an immobilized buffer system to control pH... This buffering system is identical to the Dupel B.L.U.E. iontophoresis electrode in terms of mechanism of action, materials, and function." | |
| Materials of Construction Equivalence | "The Empi Action Patch uses the identical adhesive foam backing as that used in the Empi Buffered Iontophoresis Electrodes." |
| Mode of Operation Equivalence | "[The Empi Action Patch] operates to deliver a calibrated and fixed dose of ionic solution... After delivery of the specified dose, an LED indicator light extinguishes indicating that that the Patch can be removed." This mode of operation is described as similar to predicate devices, particularly the Birch Point IontoPatch (discrete current * time dose delivery) and Empi Dupel systems (buffering mechanism). |
The following information cannot be provided from the given document, as it pertains to clinical performance studies, which are typically not required for 510(k) submissions based on substantial equivalence to predicate devices for this type of medical device.

- Not provided. This document does not describe a test set or associated data provenance from a performance study.
- 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/provided. No test set or ground truth establishment by experts is described.
- 4. Adjudication method (e.g., 2+1, 3+1, none) for the test set
- Not applicable/provided. No test set or adjudication method is described.
- 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/provided. This device is an iontophoresis system, not an AI-assisted diagnostic tool. An MRMC study is irrelevant in this context.
- 6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
- Not applicable/provided. This is not an algorithm-based device.
- 7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- Not applicable/provided. No clinical studies requiring ground truth are described. The "ground truth" for 510(k) equivalence is generally the established safety and efficacy of the predicate devices.
- 8. The sample size for the training set
- Not applicable/provided. No training set for an algorithm is relevant to this device submission.
- 9. How the ground truth for the training set was established
- Not applicable/provided. No training set for an algorithm is relevant to this device submission.
