Intended Use

The EMS9UA Transcranial Doppler Ultrasound System is intended for use as a diagnostic ultrasound fluid flow analysis system:

  1. For the measurement of cerebral artery blood velocities to determine the presence of hemodynamically significant deviations from normal values
  2. To assess arterial cerebral blood flow for the occurrence of micro embolic signals. Vessels intended for observation include, but are not limited to the middle, anterior and posterior cerebral arteries, via the temporal windows, the vertebral mid basilar arteries via the foramen magnum and the ophthalmic artery and intracranial internal carotid artery via the eye.

The Roboprobe Headband facilitates monitoring use by its ability to track the Doppler signal. The EMS9UA Transcranial Doppler is intended for use during:

a) Diagnostic exams
b) Surgical interventions

The device is not intended to replace other means of evaluating vital patient physiological processes, is not intended to be used in fetal applications, and is not intended to be used inside the sterile field.

Device Description

Shenzhen Delicate believes that the Model EMS-9UA is substantially equivalent to its EMS OU Transcranial Doppler which was cleared on May 5, 2006 510kH K060112. The EMS-9UA has the same device description except that the head frame used for longer term monitoring has the ability to track the Doppler signal and therefore not lose the signal with patient movement and time. The tracking is accomplished by adding to the EMS9U an additional circuit which detects the ultrasound Doppler return and positions the face of the probe in the headband to maximize the detected ultrasound return. The headband electronics does not change or interfere with the transmitted ultrasound. Except for the servo motor controller added to the circuitry of the EMS9U range and the software added to control it, and the modifications to the INNSO Tange and the servo motor controlled probe, the EMS9U range and the EMS- 9UA are identical internally and functionally. The probes are identical to those cleared in K060112.

AI/ML Overview

Here's a breakdown of the acceptance criteria and study information for the EMS9UA Transcranial Doppler with Robotic Probe Headband, based on the provided document:

Acceptance Criteria and Device Performance

The document does not explicitly state quantitative performance acceptance criteria (e.g., specific accuracy thresholds) for the EMS9UA device. Instead, the "acceptance criteria" are implied by compliance with safety and industry standards, and the demonstration of safety and effectiveness through performance testing and a clinical trial, showing substantial equivalence to the predicate device.

The reported device performance emphasizes its capabilities as a diagnostic ultrasound fluid flow analysis system for measuring cerebral artery blood velocities and detecting micro embolic signals, with the added functionality of the robotic headband to track the Doppler signal.

Table of Acceptance Criteria and Reported Device Performance:

Study Information

The document describes a clinical trial, though details are limited.

  1. Sample Size Used for the Test Set and Data Provenance:

    • Sample Size: 100 patients.
    • Data Provenance: Not explicitly stated (e.g., country of origin). The study is referred to as a "clinical trial," which typically implies prospective data collection, but this is not explicitly confirmed.
  2. 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 study compared the EMS9UA with a predicate device, but it doesn't describe who evaluated the outputs or established a ground truth for the comparison.
  3. Adjudication Method for the Test Set:

    • This information is not provided in the document.
  4. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done:

    • Yes, a comparative study was done. A "clinical trial involving 100 patients was conducted comparing the EMS9UA Transcranial Doppler with Robotic Headband with the Spencer Technologies Marc 600 predicate headband."
    • Effect Size: The document states that the device "was found to be safe and effective" in comparison to the predicate, implying non-inferiority or similar performance. However, no specific quantitative effect size or details on how human readers improved with AI vs. without AI assistance are provided. The robotic headband's function is to track the Doppler signal and not lose the signal with patient movement and time, which is a practical improvement in monitoring, rather than an AI-driven interpretive enhancement for human readers. This device's primary improvement is in signal stability and monitoring duration, not necessarily in diagnostic interpretation per se.
  5. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done:

    • The document implies that the device is a diagnostic ultrasound system intended for use by "trained medical personnel." It is not described as an AI algorithm providing standalone diagnoses. The robotic probe head is an automated feature for signal tracking, which enhances the device's performance, but it's not suggested that it operates entirely without human oversight or interpretation of the ultrasound data. Therefore, a standalone algorithm-only performance study as typically understood for AI diagnostics is not applicable/not described.
  6. The Type of Ground Truth Used:

    • This is not explicitly stated. Given that it's a comparative study against a predicate device, the "ground truth" for the comparison would likely be the diagnostic output or clinical utility of the predicate device. However, details on how this was established or if an independent clinical ground truth (e.g., pathology, follow-up outcomes) was used are not provided.
  7. The Sample Size for the Training Set:

    • This is not applicable/not provided. The document describes a medical device (Transcranial Doppler with a robotic headband for signal tracking), not a typical AI model that undergoes a separate training phase with a distinct training dataset. The "training" for such a device would involve engineering design, calibration, and internal verification.
  8. How the Ground Truth for the Training Set Was Established:

    • This is not applicable/not provided for the reasons stated above.

Dear Mr. Stern:

We have reviewed your Section 510(k) premarket 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 legally marketed predicate 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.

This determination of substantial equivalence applies to the following transducers intended for use with the EMS9UA Transcranial Doppler Robotic Probe Headband, as described in your premarket notification:

Transducer Model Number

2 MHz
4 MHz
8 MHz

{6}------------------------------------------------

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), 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. In addition, FDA may publish further announcements concerning your device in the Federal Register.

(a)
Identification. A diagnostic ultrasonic transducer is a device made of a piezoelectric material that converts electrical signals into acoustic signals and acoustic signals into electrical signals and intended for use in diagnostic ultrasonic medical devices. Accessories of this generic type of device may include transmission media for acoustically coupling the transducer to the body surface, such as acoustic gel, paste, or a flexible fluid container.(b)
