Here's a breakdown of the acceptance criteria and study details for the Imperative Care, Inc. Symphony™ Thrombectomy System, specifically for the expanded pulmonary embolism indication, based on the provided 510(k) clearance letter:

1. Table of Acceptance Criteria and Reported Device Performance

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

• Sample Size for Clinical Study (SYMPHONY-PE):

  • ITT Cohort (Safety Analysis): 109 subjects
  • mITT Cohort (Efficacy Analysis - device only used, no thrombolytics/other devices within 48h): 106 subjects
  • Primary Efficacy Analysis Population (mITT with paired RV/LV measurements): 102 subjects

• Data Provenance: The SYMPHONY-PE clinical study was a prospective, multicenter, single-arm, open label study conducted across 19 sites in the U.S.

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

• Ground Truth for Clinical Endpoints:
  • Primary Efficacy Endpoints (RV/LV measurements): Adjudicated by an independent imaging core lab. The specific number and qualifications of experts within this core lab are not detailed in the provided document.
  • Primary Safety Endpoints (Major Adverse Events): Adjudicated by an Independent Safety Board (ISB). The specific number and qualifications of experts on this board are not detailed in the provided document.
  • Clinical Events Committee (CEC): Also reviewed safety endpoints data. The number and qualifications are not detailed.

4. Adjudication Method for the Test Set

• The document states that the primary efficacy endpoint (mean reduction in RV/LV) was "independent core-lab adjudicated."
• The primary safety endpoint (MAE rate) was "adjudicated by the Independent Safety Board (ISB)."
• No specific method like "2+1" or "3+1" concensus is described for the adjudication processes. It implies that the core lab and ISB performed their respective adjudications, likely following their own established protocols.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

• No, an MRMC comparative effectiveness study was not done. The SYMPHONY-PE study was a single-arm study evaluating the safety and effectiveness of the device itself against pre-specified performance goals, not comparing its performance or human reader performance with and without AI assistance, or against another device.
• Therefore, no effect size for human reader improvement with AI vs. without AI assistance is reported, as AI is not explicitly mentioned as part of the system or as an aid to human readers in this context.

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

• No, a standalone (algorithm-only) performance study was not done. The Symphony™ Thrombectomy System is a medical device for mechanical thrombectomy, not an AI or software algorithm that provides a diagnostic output in a standalone manner. The clinical study evaluated the device in vivo during actual procedures.

7. The Type of Ground Truth Used

• Clinical Outcomes Data: For the SYMPHONY-PE clinical study, the ground truth was based on clinical outcomes measured in human subjects.
  • Efficacy: Reduction in RV/LV ratio, assessed by CT Angiography (CTA) and adjudicated by an independent imaging core lab. This is a quantitative, image-based clinical measurement.
  • Safety: Rates of Major Adverse Events (MAE) including bleeding, mortality, and device-related SAEs, adjudicated by an Independent Safety Board and CEC. This is based on clinical observations and event reporting.

8. The Sample Size for the Training Set

• Not applicable / Not provided. The Symphony™ Thrombectomy System is a mechanical device, not a machine learning or AI model. Therefore, there is no "training set" in the context of algorithm development.
• The document does describe extensive in-vitro bench testing and in-vivo GLP pre-clinical animal testing to validate the device's performance prior to human clinical trials.

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

• Not applicable / Not provided. As mentioned above, there is no "training set" for this mechanical device. The ground truth for its development and verification was established through various engineering tests and animal studies, which are designed to validate physical performance, material properties, and biocompatibility against established standards and safety profiles.

The Excipio LV Prime Thrombectomy Device is indicated for the nonsurgical removal of emboli and thrombi from peripheral blood vessels.

The Excipio LV Prime Thrombectomy Device consists of a Thrombectomy Catheter to mechanically displace thrombus when used with an aspiration catheter. The device will be sold as a sterile, single use device.

The Thrombectomy Catheter is a mechanical thrombus displacement device with a nitinol braided component (basket) at the distal end that can be opened and closed via an activation wire that attaches to the distal end of the braid and attaches to a proximal handle. The operator can open the braided component to a diameter that best matches the target vessel (6-16 mm in diameter). The thickness of the basket wires enhances the radiopacity to facilitate visualization under fluoroscopy without the need for additional radiopaque markers.

Let's break down the information regarding the acceptance criteria and study for the Excipio LV Prime Thrombectomy Device, based on the provided FDA 510(k) clearance letter.

It's important to note that this document is a 510(k) clearance letter, which focuses on demonstrating substantial equivalence to a predicate device. Therefore, the "study" described here is primarily a non-clinical bench testing campaign aimed at proving the new device performs similarly and meets a defined set of engineering and performance specifications. There is no clinical study involving human (or animal) subjects described in this document for the Excipio LV Prime Thrombectomy Device. Thus, concepts like "human readers," "AI assistance," "effect size," or "ground truth for training/test set" in the context of clinical outcomes or diagnostic accuracy are not applicable to this type of device and submission.

Acceptance Criteria and Reported Device Performance

The document describes non-clinical laboratory testing performed to support the substantial equivalence. The acceptance criteria for these tests are implicitly that the device met the criteria and functioned as intended, with a performance profile similar to predicate devices. Specific quantitative acceptance criteria or detailed reported performance values are not explicitly stated in this summary. Instead, it broadly states that the device "met all acceptance criteria" and "functioned as intended."

Table of Acceptance Criteria and Reported Device Performance:

Study Details: Non-Clinical Bench Testing

Since this is a thrombectomy device and the submission is for 510(k) clearance based on substantial equivalence, the "study" referred to is a series of in vitro bench tests.

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

   • The document does not explicitly state the specific number of units tested for each non-clinical test (e.g., how many devices were subjected to kink resistance or tensile testing). This level of detail is typically found in the full 510(k) submission, not the summary.
   • Data Provenance: All data is from in vitro bench testing conducted by the manufacturer, Contego Medical, Inc. The country of origin for this testing is not specified, but it would typically be conducted at the manufacturer's facilities or a contracted testing lab. This is by definition retrospective in the sense that the testing is performed before submission for clearance.

2. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:

   • Not Applicable. For non-clinical bench testing of a medical device, "ground truth" is established by engineering specifications, validated test methods, and industry standards (e.g., ISO standards). There are no "experts" establishing a clinical judgment ground truth in this context. The "experts" involved would be the design engineers, quality engineers, and test technicians who define the test protocols and interpret the results against the defined acceptance criteria.

3. Adjudication Method for the Test Set:

   • None Applicable. Adjudication methods like "2+1" or "3+1" are used in clinical studies or image interpretation studies where multiple human readers' opinions need to be reconciled to establish a ground truth. For bench testing, results are typically objective measurements compared directly against predetermined pass/fail criteria.

4. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

   • No, not done. An MRMC study is relevant to diagnostic imaging devices or other technologies where human interpretation is involved. This device is a mechanical thrombectomy device; its performance is evaluated by its physical characteristics and efficacy in removing thrombus in a lab setting, not by aiding human readers in diagnosis.

5. Standalone (Algorithm Only Without Human-in-the-Loop Performance):

   • Not Applicable. This device is an invasive medical device, not a software algorithm. Its use inherently involves a human operator (a clinician) and is not "standalone" in the sense of an unassisted algorithm making decisions.

6. Type of Ground Truth Used:

   • For the non-clinical testing, the "ground truth" is defined by:
     • Engineering specifications and design requirements: For dimensional, kink resistance, torsional strength, tensile, radial force, and corrosion testing.
     • Validated test methods and industry standards (e.g., ISO 10993-1): For biocompatibility, simulated use, and clot removal testing.
     • Manufacturer's internal quality standards.

7. Sample Size for the Training Set:

   • Not Applicable. The concept of a "training set" applies to machine learning algorithms. This device is a physical, mechanical medical device, not an AI/ML system.

8. How the Ground Truth for the Training Set Was Established:

   • Not Applicable. As above, there is no training set for this type of device.

The System is provided with a 60-cc dual action manual syringe which allows for directional flow control and directs aspirated blood and clot into the Clot Canister.

The provided text describes the regulatory clearance of a medical device, the Aventus Thrombectomy System, and outlines the performance data submitted to support its substantial equivalence. However, the document does NOT contain information about an AI/Software component that would require "acceptance criteria" based on metrics like sensitivity, specificity, accuracy, or an MRMC study.

The software testing mentioned refers to:

• "Software documentation was leveraged from the reference device as recommended by FDA Guidance: Content of Premarket Submissions for Device Software Functions, issued June 14, 2023." This indicates that the software functions are likely related to guiding the device's operation, sensing, or control rather than an AI-driven diagnostic or interpretative function. There is no mention of AI, machine learning, or algorithms for image analysis or diagnostic support.

Therefore, I cannot provide the requested information about acceptance criteria, test set details (sample size, provenance, expert ground truth, adjudication), MRMC studies, standalone performance, or training set details because the provided document does not indicate the presence of such an AI/ML component.

The performance data listed pertains to the physical device itself (biocompatibility, sterilization, packaging, electrical safety, bench testing, animal studies, and a clinical trial on the device's safety and effectiveness in treating pulmonary embolism).

If the device did indeed have an AI/ML component, the type of information you requested (acceptance criteria, ground truth establishment, MRMC study, etc.) would be critical for its regulatory clearance. Based on the provided text, the Aventus Thrombectomy System appears to be a mechanical thrombectomy device with some electronic/software components for its control and sensing, but not for AI-assisted image analysis or diagnostic capabilities.

The document focuses on the substantial equivalence of the Liberant Thrombectomy System to a predicate device (Penumbra Indigo Aspiration System) based on:

• Indications for Use: Both systems are indicated for the removal of fresh, soft emboli or thrombi from peripheral arterial and venous systems.
• Operating Principle/Technological Design: Both utilize continuous aspiration and fragmentation tools (clotbuster/separator).
• Catheter Specifications: Similar sizes, lengths, and guidewire compatibility.
• Non-Clinical Data: Extensive performance, biocompatibility, shelf-life, sterilization, packaging, software validation (for the pump control), and electrical/EMC testing were performed. This type of "software validation" typically refers to embedded software controlling the pump mechanics, not an AI/ML diagnostic or predictive algorithm.

Therefore, I cannot provide the requested information regarding AI/ML device acceptance criteria and study details because the provided document describes a non-AI medical device.

The Aventus Thrombectomy System is intended for use in the peripheral vasculature.

The Aventus Thrombectomy System is a catheter-based manual aspiration system designed for minimally invasive removal of emboli and thrombi from the peripheral vasculature and/or infusing fluids into the peripheral vasculature. The System is comprised of the following major components:

• Aventus Thrombectomy Catheter .
• Clot Management System consisting of:
• . Aspiration Syringe
• . Clot Canister
  The System is compatible with standard introducer sheaths (24F or 16F). 4F or 5F Navigation Catheters (based on Aventus Thrombectomy Catheter model), and is to be used with 0.035" guidewires. The System is provided sterile and is intended for single use only.
  The Aventus Thrombectomy Catheter includes an atraumatic radiopaque Distal Tip with embedded sensors, and an angled aspiration orifice for directional aspiration and navigation without a dilator. The Catheter Handle assists the clinician in navigating within the vasculature and includes a Sensing Indicator and houses the Sensing electronics.
  The Aspiration Catheter shaft incorporates a metallic reinforcement layer made of stainless steel, an inner liner and polymeric outer jacket having variable stiffness.
  The System is provided with a 60-cc dual action manual syringe which allows for directional flow control and directs aspirated blood and clot into the Clot Canister.

This document is a 510(k) Premarket Notification from the FDA regarding the Aventus Thrombectomy System. It describes the device, its intended use, and substantial equivalence to a predicate device.

However, the provided text does not contain any information about an AI/software component that would require a study proving the device meets acceptance criteria related to AI performance, or any details about a clinical study involving human readers or ground truth establishment. The mentions of "software" and "refine the algorithm" are general and don't provide specifics on AI acceptance criteria or performance studies.

Therefore, I cannot fulfill your request for detailed information about acceptance criteria for an AI component, sample sizes for test sets, expert involvement in ground truth, MRMC studies, standalone performance, or training set details. This document primarily focuses on the physical device (catheter-based thrombectomy system) and its equivalence to a prior version, primarily through bench, biocompatibility, sterilization, packaging, and electrical safety testing.

The relevant information regarding software is:

• Software Testing: "Software documentation and testing was updated from the predicate device as recommended by FDA Guidance: Content of Premarket Submissions for Device Software Functions, issued June 14, 2023."
• Device Modification: "Update of the device software to refine the algorithm and account for the reduction in diameter."

These statements indicate that software was updated and tested according to FDA guidance, but they do not provide specific performance metrics, acceptance criteria for an AI algorithm (e.g., sensitivity, specificity, AUC), or details of a study setup that would validate such metrics. The "algorithm" mentioned likely refers to control or sensing algorithms for the catheter, not a diagnostic or prognostic AI.

In summary, the provided document does not contain the information needed to address your questions regarding AI acceptance criteria and study details.
