Here's an analysis of the provided text regarding the SEIN SE-30 TENS device, framed by the requested acceptance criteria and study information.
It's important to note that the provided document is a 510(k) summary for a Transcutaneous Electrical Nerve Stimulator (TENS) device. For such devices, "acceptance criteria" and "study" typically refer to demonstrating substantial equivalence to a predicate device, as well as adherence to recognized performance standards. This is different from the type of clinical performance study often associated with AI/software devices. The acceptance criteria here are about demonstrating that the new device is as safe and effective as a legally marketed predicate device.
Acceptance Criteria and Study for SEIN SE-30 TENS Device
The SEIN SE-30 TENS device demonstrated substantial equivalence to a predicate device (Graham-Field, Inc. Micro TENS Plus) and compliance with the ANSI/AAMI NS4-1985 standard. The "acceptance criteria" are implied by these comparisons and the requirements of the 510(k) process for demonstrating substantial equivalence.
1. Table of Acceptance Criteria and Reported Device Performance
For a TENS device seeking 510(k) clearance, the "acceptance criteria" are generally met by demonstrating that the device is as safe and effective as a legally marketed predicate device and complies with relevant performance standards. The reported device performance is primarily a comparison of technical specifications.
| Acceptance Criteria (Implied) | SEIN SE-30 TENS Reported Performance | Satisfies? |
|---|---|---|
| Substantial Equivalence: | ||
| - Equivalent intended use | Symptomatic relief and management of chronic pain, post-surgical/post-traumatic pain. (Identical to predicate) | Yes |
| - Similar technological characteristics (where differences don't raise new questions of safety/effectiveness) | See "Comparison of General Specifications" below; differences evaluated by FDA. | Yes |
| Compliance with Recognized Standards: | ||
| - ANSI/AAMI NS4-1985 (Electromyographs and Evoked Potential Instruments) | Device was tested and found to meet the requirements of ANSI/AAMI NS4-1985. | Yes |

2. Sample Size Used for the Test Set and Data Provenance
For TENS devices seeking 510(k) clearance, there isn't typically a "test set" in the sense of a dataset for an AI algorithm. Instead, the "test" involved comparing the new device against a predicate device's specifications and performance against a recognized standard (ANSI/AAMI NS4-1985).
- Sample Size for Test Set: Not applicable in the context of a dataset for an AI algorithm. The "test" involved a single physical SEIN SE-30 TENS device being evaluated against specifications and standards.
- Data Provenance: The data is primarily derived from engineering specifications, design documents, and testing results of the SEIN SE-30 TENS device, alongside the known specifications of the predicate device. The testing was conducted by SEIN Electronics Co., Ltd. in Korea. It's a "prospective" evaluation in the sense that the device was specifically tested to meet the standard and demonstrate equivalence.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- Number of Experts: Not applicable in the context of establishing ground truth for image/data interpretation. This summary does not mention any expert review of clinical cases.
- Qualifications of Experts: Not applicable. The "ground truth" for this regulatory submission is the established performance characteristics of the predicate device and the requirements of the ANSI/AAMI NS4-1985 standard.
4. Adjudication Method for the Test Set
- Adjudication Method: Not applicable. There was no "test set" in the context of clinical data requiring expert adjudication. The comparison was primarily based on objective technical specifications and standard compliance.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done
- MRMC Study: No. This type of study is not typically required or performed for TENS device 510(k) submissions, which focus on electromechanical similarity and performance standard compliance rather than diagnostic accuracy or human interpretation.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
- Standalone Performance: Not applicable. The SE-30 TENS is a physical medical device, not an AI algorithm. Its performance is inherent in its design and operation, not subject to standalone algorithmic testing.
7. The Type of Ground Truth Used
- Type of Ground Truth: For the purpose of this 510(k) submission, the "ground truth" is:
- The established technical specifications and therapeutic claims of the legally marketed predicate device (Graham-Field, Inc. Micro TENS Plus).
- The requirements of the recognized industry standard ANSI/AAMI NS4-1985.
- The intended use for Transcutaneous Electrical Nerve Stimulators (pain relief).
8. The Sample Size for the Training Set
- Sample Size for Training Set: Not applicable. The SEIN SE-30 TENS is a physical TENS device and does not involve machine learning or a "training set" in the context of AI.
9. How the Ground Truth for the Training Set Was Established
- Ground Truth for Training Set: Not applicable, as there is no training set for this type of device.
In summary, the K991397 submission for the SEIN SE-30 TENS device demonstrated its "acceptance criteria" were met by proving substantial equivalence to a predicate device through a comparison of technical specifications and by showing compliance with a relevant performance standard (ANSI/AAMI NS4-1985). The framework of AI/software device evaluation (test sets, ground truth by experts, MRMC studies) does not directly apply to this traditional medical device submission.

Dear Mr. Hwang:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed
