The Optima Coil System is intended for the endovascular embolization of intracranial aneurysms and other neurovascular abnormalities such as arteriovenous malformations and arteriovenous fistulae. The Optima Coil System is also intended for vascular occlusion of blood vessels within the neurovascular system to permanently obstruct blood flow to an aneurysm or other vascular malformation and for arterial and venous embolizations in the peripheral vasculature.

The Optima Coil System is a series of specialized coils that are inserted into the vasculature under angiographic visualization to embolize intracranial aneurysms and other vascular anomalies. The system consists of an embolization coil implant comprised of platinum and tungsten, affixed to a delivery pusher to facilitate insertion into the hub of a microcatheter. The system is available in various shapes, lengths and sizes. The devices are to be placed into aneurysms to create blood stasis, reducing flow into the aneurysm and thrombosing the aneurysm. Upon positioning coils into the aneurysm, the coils are detached from the delivery pusher in a serial manner until the aneurysm is occluded.

The provided text is a 510(k) Summary for a medical device called the "Optima Coil System." It describes the device, its intended use, and its comparison to a predicate device. It also includes a table of performance data from bench testing. However, this document does not contain information about a study involving human readers or AI assistance, or any data related to diagnostic accuracy, sensitivity, or specificity.

The "acceptance criteria" and "device performance" described are for bench testing only, which evaluates the physical and functional characteristics of the device itself, not its performance in a clinical scenario involving human interpretation or AI.

Therefore, I cannot fulfill the request for information related to:

• A table of acceptance criteria and reported device performance in a human-AI study. The provided table only covers bench tests.
• Sample size used for the test set and data provenance for a human-AI study.
• Number of experts used to establish ground truth and their qualifications for a human-AI study.
• Adjudication method for a human-AI study.
• Multi-reader multi-case (MRMC) comparative effectiveness study or effect size.
• Standalone (algorithm only) performance.
• Type of ground truth used (expert consensus, pathology, outcomes data, etc.) for a human-AI study.
• Sample size for the training set for an AI study.
• How ground truth for the training set was established for an AI study.

The document's "Performance Data - Bench" section is directly relevant to the acceptance criteria of the device's physical properties and functionality, not an AI or diagnostic performance study.

Here's the information that can be extracted from the provided text regarding device acceptance criteria and performance (bench testing):

Device Acceptance Criteria and Reported Performance (Bench Testing)

Explanation of the Bench Study (based on the provided text):

The performance data presented is from non-clinical bench testing. Its purpose was to evaluate changes made to the Optima Coil System (e.g., new coil sizes and combinations of dimensions) and to demonstrate its substantial equivalence to the previously cleared predicate device (K200030).

• Sample size: Not explicitly stated for each bench test, but implied to be "test samples."
• Data provenance: Bench testing results, implying in-house lab testing, not clinical data from patients or specific countries. It is retrospective in the sense that it evaluates a final product design.
• Experts for ground truth: Not applicable for this type of bench testing. Ground truth is based on engineering specifications, physical measurements, and performance standards.
• Adjudication method: Not applicable. Results are based on physical measurements and functional checks against pre-defined engineering criteria.
• MRMC Comparative Effectiveness Study: No, this document does not describe such a study.
• Standalone Performance: Not applicable in the context of AI; this refers to the physical device's performance.
• Type of Ground Truth: Engineering specifications, physical dimensions, material properties, and functional performance in simulated environments.
• Training Set Sample Size/Ground Truth for Training Set: Not applicable, as this document describes bench testing of a physical medical device, not the development or training of an AI algorithm.

In summary, the provided document focuses solely on the substantial equivalence of a physical neurovascular embolization device based on bench testing of its modifications. It does not contain any information related to AI performance, human-in-the-loop studies, or diagnostic efficacy.
