Intended Use

For the ASTRA TEE® -

The ASTRA TEE® automated reprocessor facilitates high-level disinfection and rinsing of 1 or 2 transesophageal ultrasound probes using FDA cleared and Civco Medical Solutions approved high-level liquid disinfectants.

For the ASTRA VR™ -

The ASTRA VR™ automated reprocessor facilitates high-level disinfection and rinsing of 1 or 2 endovaginal/endorectal ultrasound probes using FDA cleared and Civco Medical Solutions approved high-level liquid disinfectants.

Device Description

The ASTRA Product Family of automated reprocessors are floor standing electromechanical lab equipment that facilitate high-level liquid disinfection of ultrasound probes that have been enzymatically pre-cleaned.

AI/ML Overview

The provided document is a 510(k) Pre-Market Notification for medical devices (ASTRA TEE® Transesophageal Probe Reprocessor and ASTRA VR™ Endovaginal/Endorectal Probe Reprocessor). It outlines the device description, intended use, and a comparison to predicate devices, focusing on demonstrating substantial equivalence. The document primarily discusses the device's technical specifications and the testing conducted to ensure its safety and effectiveness in controlling high-level disinfection processes.

Unfortunately, the provided document does not contain the specific details required to answer all parts of your request about acceptance criteria met by a "device" in the context of an AI/human-in-the-loop study. The device in question here is an automated reprocessor for ultrasound probes, not an AI-powered diagnostic tool, and the performance criteria are related to disinfection efficacy, not diagnostic accuracy.

Therefore, I cannot populate most of the requested table and details, as they pertain to performance metrics and study designs common for AI-based diagnostic devices (e.g., sensitivity, specificity, reader performance studies, expert adjudication for ground truth).

However, I can extract the information relevant to the device's operational performance and the studies conducted to support its substantial equivalence.

Here's what can be extracted and what cannot be from the provided text:

What can be extracted:

  • Acceptance Criteria (Performance Attributes): The core performance attribute for this device is its ability to "control the HLD temperature, soak time, and rinse cycle to facilitate ≥6 Log reduction of M. terrae using Metricide OPA Plus, Cidex OPA, and Resert XL." This is the primary functional performance claim.
  • Study That Proves the Device Meets Acceptance Criteria:
    • Performance Testing Summary:
      • "The ASTRA system maintains time and temperature required for disinfection as per HLD manufacturers' specifications."
      • "The ASTRA system passed Safety and EMC testing."
      • "The ASTRA system passed Simulated use and Residual testing."
      • "The ASTRA system passed In-use testing."
    • Efficacy (Disinfection and Residual testing): "Pass as per simulated use (6log reduction of M. terrae), In-use Testing (complete kill) and residual testing (ISO10993-5 cytotoxic effect of

§ 892.1570 Diagnostic ultrasonic transducer.

(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)
Classification. Class II.
