Device Description

The Nihon Kohden Smart Cable NMT Module (NMT Module) and Accessories is an optional accessory for the Nihon Kohden bedside monitoring systems. The Smart Cable NMT Module and Accessories TOF (Train of Four) are based on EMG technology. With this system, the user can apply electrical stimulation on the ulnar nerve to detect the muscle's action potential. The reaction to the electrical impulse can be visualized on the connected monitoring system. The Smart Cable NMT Module and Accessories can assist medical personnel to quantitatively determine the level of muscle relaxation. This information can be used to determine the dose of muscle relaxants and regional anesthetics when performing anesthesia in a clinical setting. It is intended for use by medical personnel in the operating room, recovery room, or intensive care unit.

The NMT Module is a system comprised of NMT Module, Main Cable, Holder, and EMG Electrode. The NMT module is connected to an electrode via Main Cable. The electrode is a single-use electrode array and each array includes two stimulating electrodes, two recording electrodes, and one ground electrode. The NMT module can transmit an electrical stimulation pulse to the patient and can receive EMG signals via the electrode array. The captured data from the disposable electrode is sent to the monitoring system via the Smart Cable interface connector. The various stimulation settings are also sent to the monitoring system to display.

The AF-201P NMT Module is used to control the electrical stimulation and to measure the response. The operational setting is controlled via buttons on the module or a touch screen.

AI/ML Overview

The provided text describes the acceptance criteria and study data for the Smart Cable NMT Module and Accessories, as well as the Life Scope BSM-3000, BSM-6000, and CSM-1901 Bedside Monitors. However, the document is a 510(k) summary for substantial equivalence, which primarily focuses on comparing the new device to existing predicate devices and demonstrating that it is as safe and effective. It does not contain an explicit table of acceptance criteria and reported device performance in the format typically used for a detailed study report.

Instead, the document states that various tests were performed and that the devices "met all the acceptance criteria" or "performed within specifications." It also notes that "No clinical tests have been submitted, referenced or relied on in the premarket notification submission for a determination of substantial equivalence." This implies that the acceptance criteria for performance were likely derived from industry standards (IEC 60601-1, IEC 60601-1-2, IEC 60601-2-40, ANSI/AAMI EC12:2000), internal company specifications, and comparison to predicate devices, rather than from a standalone clinical study with an explicit set of primary and secondary endpoints and predefined performance metrics.

Therefore, many of the requested details such as sample size for the test set, data provenance, number and qualifications of experts, adjudication methods, MRMC studies, standalone algorithm performance, and ground truth establishment from actual patient data (for algorithm training/testing) are not present in this 510(k) summary. This is typical for a 510(k) submission where substantial equivalence is demonstrated through non-clinical performance and engineering validation rather than through new clinical studies, especially for devices where modifications are minor or where performance can be adequately assessed through bench testing and comparisons to established technological characteristics of predicates.

Below is an attempt to address the request based on the information available in the provided text, while also explicitly stating what information is not provided.

Acceptance Criteria and Device Performance (Based on available information):

The document does not present a formal table of acceptance criteria with corresponding device performance results for each specific metric. Instead, it broadly states that the devices underwent various non-clinical tests and met the acceptance criteria. The acceptance criteria were primarily based on compliance with relevant industry standards and comparison to the performance specifications of predicate devices.

Summary of Device Performance and Acceptance (Inferred from the document):

Environmental and Safety Testing	Subjected to tests. Results confirmed performance within specifications.
Overall Performance	Confirmed the device performed within specifications.

Details Regarding the Study/Testing:

A table of acceptance criteria and the reported device performance:
- As noted above, a formal table is not provided. The document states that various tests (electrical safety, EMC, software V&V, operational performance, environmental performance, biocompatibility, shelf life, electrode performance for NMT module; and software integration, EMC, environmental, safety for Bedside Monitors) were conducted and that the devices "met all the acceptance criteria" or "performed within specifications." The specific quantitative pass/fail thresholds for each test are not detailed in this summary.
Sample sized used for the test set and the data provenance:
- Sample Size: Not explicitly stated for any of the performance tests (e.g., how many devices were tested, how many signal samples were used for performance evaluation).
- Data Provenance: The tests are described as non-clinical (bench testing, software validation). There is no indication of patient data being used for device performance validation as part of this 510(k) submission. The document explicitly states: "No clinical tests have been submitted, referenced or relied on in the premarket notification submission for a determination of substantial equivalence."
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable as no clinical study or expert-adjudicated ground truth dataset is described for device performance validation. The ground truth for engineering and performance tests would be defined by the measurement standards and validation protocols themselves (e.g., a calibrated instrument reading as ground truth for a measurement accuracy test).
Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- Not applicable as no clinical study or expert adjudication process for a test set is described.
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 MRMC study was done, as explicitly stated: "No clinical tests have been submitted, referenced or relied on in the premarket notification submission." The device is a monitor, not an AI-assisted diagnostic tool that would typically involve human reader improvement studies.
If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Performance validation was conducted via non-clinical testing against specifications and standards, which generally assesses the algorithm's (or device's) performance in isolation under controlled conditions (e.g., accuracy of readings, alarm thresholds). Specific "standalone performance" metrics (like sensitivity/specificity for a diagnostic algorithm) are not detailed as the device is a measurement and monitoring system.
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- For the non-clinical tests described, the "ground truth" would be the known inputs or reference values from calibrated test equipment, as per engineering and quality assurance standards. No medical "ground truth" (e.g., expert consensus, pathology, outcomes data) from patients was used for device verification or validation in this submission.
The sample size for the training set:
- Not applicable. The document describes a medical device (monitor) with firmware/software, not an AI/ML algorithm that would typically require a distinct training set (beyond standard software development and testing).
How the ground truth for the training set was established:
- Not applicable, as there is no specific "training set" described for an AI/ML algorithm.
