This document is a 510(k) Pre-market Notification for a medical device (Indigo Aspiration System - Lightning Aspiration Tubing) and as such, it focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving the device meets acceptance criteria through a comparative effectiveness study with human readers assisting AI or an AI standalone system. The concepts of AI assistance, multi-reader multi-case studies, and specific performance metrics like sensitivity/specificity for AI are not applicable here.

The "acceptance criteria" and "study that proves the device meets the acceptance criteria" in this context refer to the engineering and performance testing conducted to ensure the new device functions as intended and is equivalent to the predicate device. The prompt's request for information largely aligns with the type of evaluation performed for an AI-powered diagnostic device, which is not what this document describes.

Therefore, providing a direct answer to all points of the prompt as though the document describes an AI diagnostic or assistive device study would be factually incorrect and misleading.

However, I can extract the relevant information regarding the engineering/performance acceptance criteria and the supporting studies from the provided document as it pertains to the device's substantial equivalence.

Here's how the information can be broken down based on the document's content, focusing on what is present:

Device: Indigo Aspiration System - Lightning Aspiration Tubing

Regulatory Class: Class II

Product Code: QEW (Embolectomy Catheter)

Purpose of Submission: Demonstrate substantial equivalence to a predicate device (K180939, 110 Aspiration Tubing, modified).

1. Table of Acceptance Criteria and Reported Device Performance

The document details various non-clinical tests performed to demonstrate the device meets its design specifications and is substantially equivalent to the predicate. These are more akin to engineering and material acceptance criteria rather than diagnostic performance metrics.

2. Sample Size Used for the Test Set and Data Provenance

• Test Set Sample Size: Not explicitly stated as a single "test set" in the context of an AI study. The "test sets" for each specific engineering/performance test (e.g., biocompatibility, tensile strength, simulated use) would vary, but the document does not provide the exact sample sizes for each. It generally states that "units" or "the subject device" were tested.
• Data Provenance: The tests are non-clinical (bench-top, laboratory testing) and focused on device performance, not clinical patient data. The provenance is internal to Penumbra, Inc. (Alameda, CA, USA). The document does not specify if any retrospective or prospective patient data was used, as it explicitly states "Clinical Testing was not required".

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

This concept is not applicable to this 510(k) submission. "Ground truth" in the context of AI diagnostic performance is typically established by medical experts (e.g., radiologists, pathologists). Here, the "ground truth" for each test is its defined engineering specification or a generally accepted laboratory standard (e.g., ISO guidelines for biocompatibility). The experts would be engineers, chemists, and quality control professionals, but their number and specific qualifications are not detailed in this regulatory summary.

4. Adjudication Method for the Test Set

Not applicable. Adjudication methods (like 2+1 or 3+1 consensus) are used for resolving disagreements among human readers or between human readers and AI outputs in diagnostic studies. For engineering tests, results are typically binary (pass/fail) based on objective measurements against pre-defined specifications.

5. 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

Not applicable. This device is not an AI-powered diagnostic or assistive tool for human readers. It's a medical device (aspiration tubing) used in a non-AI surgical/interventional procedure. Therefore, no MRMC study with human readers and AI assistance was conducted or described.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This device does not involve an algorithm or AI.

7. The Type of Ground Truth Used

The "ground truth" for the various non-clinical tests were:

• Pre-defined engineering specifications (e.g., dimensional requirements, tensile strength minimums).
• International and national standards (e.g., ISO 10993-1 for biocompatibility, IEC/EN 60601 series for electrical safety).
• Results from previously cleared predicate devices for comparison.

8. The Sample Size for the Training Set

Not applicable. This device does not use machine learning or AI, so there is no "training set."

9. How the Ground Truth for the Training Set was Established

Not applicable, as no training set exists for this device.
