AI/ML Overview

The provided document describes the TrachCuff Cuff Controller, a medical device intended to continuously measure and automatically maintain the user-set cuff pressure of an endotracheal tube (ETT) or tracheostomy tube (TT) during mechanical ventilation.

Here's an analysis of the acceptance criteria and study information:

Acceptance Criteria and Reported Device Performance

The document does not explicitly present a table of "acceptance criteria" alongside "reported device performance" in a structured comparison for each criterion. Instead, it lists the standards and types of testing performed and then states that the device "met acceptance criteria."

However, based on the Comparison of Technological Features to Predicate Devices table (page 5-6), we can infer some key performance aspects and their comparison to the predicate device. The primary performance criteria revolve around pressure control and accuracy, and usability.

Study Details

The document describes non-clinical testing for the TrachCuff Cuff Controller.

  1. Sample size used for the test set and the data provenance:

    • Test Set Sample Size: The document does not specify a distinct "test set" in terms of patient data or a specific number of units for performance testing. Instead, it refers to laboratory testing and usability studies. For durability testing, "the device" was evaluated. For usability, it mentions a "representative population of USA clinical users," but no specific number.
    • Data Provenance: The testing was conducted in a laboratory setting ("The TrachCuff Cuff Controller was laboratory tested"). Usability testing involved "USA clinical users," suggesting prospective data collection for that specific aspect. These are non-clinical studies.
  2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

    • This information is not provided as the studies are primarily non-clinical engineering and usability tests against predefined standards and specifications, rather than clinical studies requiring expert ground truth for diagnostic or therapeutic accuracy. For usability, "USA clinical users" participated, implying healthcare professionals, but no specific number or detailed qualifications are given.
  3. Adjudication method for the test set:

    • This information is not applicable as the studies are non-clinical engineering and usability tests against predefined standards. There is no mention of adjudication for discrepancies in expert assessments.
  4. 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, an MRMC comparative effectiveness study was not done. This device is a medical device for controlling cuff pressure, not an AI diagnostic or assistive tool, so such a study would not be relevant.
  5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

    • The document implies standalone non-clinical performance testing of the device's technical specifications (pressure accuracy, electrical safety, etc.) against established standards. The device itself operates automatically to maintain cuff pressure once set by a user, so its core function is "algorithm only" in terms of maintaining the set pressure. The usability evaluation, however, involves human interaction.
  6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

    • For technical performance, the "ground truth" is defined by established engineering and medical device standards (e.g., IEC 60601-1, IEC 60601-1-2, ISO 14971, IEC 62304, ISTA 3A, IEC 62366), device specifications (e.g., pressure range, accuracy), and manufacturer's technical files (for biocompatibility). There is no "pathology" or "outcomes data" ground truth as this is not a diagnostic device.
  7. The sample size for the training set:

    • This information is not applicable/not provided. This device is a hardware-based cuff controller with embedded software, not a machine learning or AI algorithm that requires a "training set" in the conventional sense. The software development followed IEC 62304 (software lifecycle process) rather than an AI/ML model training paradigm.
  8. How the ground truth for the training set was established:

    • This information is not applicable for the reasons stated above (not an AI/ML device requiring a training set).

As summarized above, the TrachCuff Cuff Controller utilizes equivalent technological characteristics and specifications as the cleared predicate device, including the same cuff pressure setpoint ranges and limits.

Discussion of Differences in Indications to the Predicate Device:

The subject TrachCuff device and predicate device have the following differences in their indication statements regarding use for cuff control:

  • The subject device is intended to be used during ventilation of adults at least . 18 years of age who are intubated with ETT or TT. The predicate device specifies adults, pediatrics, and neonates who are intubated with ETT or TT.
  • . The subject device is intended to be used in the intensive care ward by Respiratory Therapists. The predicate device additionally specifies use for emergency medical care; during transport within and outside of the hospital; and during transfer by rescue vehicles, ship, jet, or helicopter.
  • . The subiect device may be used with any mechanical ventilator. The predicate device can be used with any ventilator, however when used with a Hamilton Medical ventilator, the predicate device adjusts the cuff pressure to values set either on the device or on the ventilator, depending on configuration.

The differences in the wording of the subject and predicate device indications for use are not critical to the intended use of the device as a cuff controller and do not affect the safety and effectiveness of the device when used as labeled for the following reasons:

  • . The subject device specifies an adult (≥ 18 years) patient population within the specified patient population of the predicate device.
  • The subject device claims for professional use environments are within the . claims of the predicate device, which specify professional as well as emergency out of hospital transport environments.
  • Both subject and predicate devices can be used with any mechanical . ventilator.

Therefore, in consideration of the above, the differences identified are not critical to the intended use of the device as a cuff controller and do not affect the safety and effectiveness of the device when used as labeled.

{10}------------------------------------------------

Discussion of Technological Differences to the Predicate Device:

The subject TrachCuff device and predicate IntelliCuff device have the following technological differences:

  • . The specified pressure accuracy of the subject device is ± 1 cmH2O; the specified accuracy of the predicate device is ± 2 cmH2O. Both devices have a pressure setpoint and display resolution of 1 cmH2O.
  • The subject device does not have a screen lock but does require a 3-second . key press, and/or user confirmation to change a setting. The predicate device has a screen lock which requires a long press to lock or unlock the panel.
  • The subiect device does not have an internal battery and is specified for use . in professional healthcare environments. The predicate device does have an internal battery and is specified for use in professional as well as out of hospital transport environments. Both devices have an internal high-capacity capacity capacitor which provides 30 seconds of operation in the event of power loss and allows the device to achieve a safe shutdown state with cuff pressure maintained.

The technological differences in the subject and predicate device are not critical to the intended use of the device as a cuff controller and do not affect the safety and effectiveness of the device when used as labeled for the following reasons:

  • . The subject device specified pressure accuracy is slightly more accurate than the predicate device accuracy. Subiect device pressure accuracy has been confirmed by testing.
  • The subject device screen functionality includes a requirement for an . intentional long press or user confirmation for any setting to be changed, which achieves a similar functionality as a screen lock.
  • The lack of an internal battery does not limit the use of the subject device for . use in professional healthcare environments. In the event of mains power interruption, the subject device is able to achieve a safe shutdown state with cuff pressure maintained, which is equivalent to the predicate device safe shutdown, as confirmed by testing.

Evidence of safety and effectiveness in support of substantial equivalence were obtained from design verification and validation testing. The differences identified above were found not to affect performance or safety through design verification activities that demonstrated conformance to specifications and performance requirements, as well as applicable medical device performance standards and other non-clinical testing.
