Intended Use

The OPTISTM Mobile System with DragonflyTM DUO or DragonflyTM OPTISTM Imaging Catheter is intended for the imaging of coronary arteries and is indicated in patients who are candidates for transluminal interventional procedures. The DragonflyTM DUO or Dragonfly™ OPTISTM Imaging Catheter is intended for use in vessels 2.0 to 3.5 mm in diameter. The Dragonfly™ DUO or DragonflyTM OPTISTM Imaging Catheter is not intended for use in the left main coronary artery or in a target vessel which has undergone a previous bypass procedure.

The OPTISTM Mobile System will further acquire radio frequency signal outputs from both a distal intracoronary pressure transducer and a proximal aortic pressure transducer to determine the physiological parameter, Fractional Flow Reserve (FFR). The physician may use the FFR parameter, along with knowledge of patient history, medical expertise and clinical judgment to determine if therapeutic intervention is indicated.

Device Description

The OPTIS Mobile System is a cart-mounted computer and Imaging Engine (or optical engine) placed inside an ergonomically designed mobile cart with the cable underground. It includes the Drive-motor and Optical Coupler (DOC), which provides the interconnection between the OPTIS Mobile System and the Dragonfly Catheter. The cart is equipped with two display monitors (one for the console operator, and the other for the physician), as well as a keyboard and mouse. The cart also contains an isolation transformer for electrical safety.

The cart includes two USB mounted FFR receivers which provide wireless reception of distal intracoronary and aortic pressure signals originating at the PressureWire® Aeris and the aortic pressure transducer (AIU). These signals are used to calculate and display the patient's Fractional Flow Reserve (FFR) on the system monitor.

The OPTIS Mobile System is comprised of the following main components:

. A rapidly scanning laser engine
A host computer with embedded application software ●
A drive-motor and optical coupler (DOC) which connects to the imaging catheter ●
A mobile console with monitors, keyboard and mouse housing laser engine and host computer, and connected to the DOC.
An imaging catheter
An optional Tableside Controller (TSC) ●
o Video interfaces for interaction with the boom monitor and angiography system

The function of the Tableside Controller (TSC) is to provide tableside system control to the Physician. The TSC communicates with the console via wireless configuration or an optional wired configuration.

The OPTIS Mobile System can perform both OCT and FFR procedures, and is compatible with Dragonfly OPTIS, DUO and JP catheters and the PressureWire Aeris. The OPTIS Mobile system provides the ability to incorporate the angiography images into the GUI, which allows users to visualize the position of OCT image data on angiography images, tightening the linkage between anatomical assessment with OCT and subsequent therapeutic actions.

AI/ML Overview

The provided text does not contain detailed acceptance criteria or a study proving that the device meets specific performance criteria in the way a clinical or performance study would typically describe for a new AI/ML device. The document is an FDA 510(k) clearance letter and summary for the LightLab Imaging, Inc. OPTIS™ Mobile System, which is an ultrasonic pulsed echo imaging system, not an AI/ML device in the context of typical AI study requirements.

The performance testing mentioned is primarily related to:

Electrical Safety and EMC: Compliance with standards like IEC 60601-1, IEC 60601-1-2.
Software Verification and Validation: Compliance with IEC 62304 and FDA regulations.
Laser Safety: Compliance with IEC 60825-1 and 21 CFR 1040.10.
Usability Engineering: Compliance with IEC 62366 and IEC 60601-1-6.
OCT Parameter and Hardware Testing: This is mentioned as part of design verification and validation, but specific acceptance criteria and results are not detailed.

The document asserts that "The results of this testing conclude the software has met these requirements" and "The results of this testing concludes the OPTIS Mobile System is determined to be safe and effective and is substantially equivalent to the ILUMIEN OPTIS predicate device." However, no specific performance metrics, sample sizes for test sets, ground truth methodology, or details of comparative effectiveness studies (like MRMC) are provided in the context of diagnostic accuracy, which would be typical for an AI/ML device.

Therefore, I cannot populate the requested table and answer many of the questions because the provided text does not contain this information. The device is cleared based on substantial equivalence to predicate devices, and the performance testing described is focused on safety, electromagnetic compatibility, software V&V, and basic system functionality, rather than detailed diagnostic accuracy metrics for an AI/ML algorithm.

Intended Use

The ILUMIEN with C7 Dragonfly, Dragonfly DUO, or Dragonfly OPTIS Imaging Catheter is intended for the imaging of coronary arteries and is indicated in patients who are candidates for transluminal interventional procedures. The C7 Dragonfly, Dragonfly DUO, or Dragonfly OPTIS Imaging Catheter is intended for use in vessels 2.0 to 3.5 mm in diameter. The C7 Dragonfly, Dragonfly DUO, or Dragonfly OPTIS Imaging Catheter is not intended for use in the left main coronary artery or in a target vessel which has undergone a previous bypass procedure.

The ILUMIEN will further acquire radio frequency signal outputs from both a distal intracoronary pressure transducer and a proximal aortic pressure transducer to determine the physiological parameter, Fractional Flow Reserve (FFR). The physician may use the FFR parameter, along with knowledge of patient history, medical expertise and clinical judgment to determine if therapeutic intervention is indicated.

The Dragonfly OPTIS Imaging Catheter with the OCT Imaging System is intended for the imaging of coronary arteries and is indicated in patients who are candidates for transluminal interventional procedures. The Dragonfly OPTIS Imaging Catheter is intended for use in vessels 2.0 to 3.5 mm in diameter. The Dragonfly OPTIS Imaging Catheter is not intended for use in the left main coronary.

Device Description

The ILUMIEN is a cart-mounted computer and Imaging Engine (or optical engine) placed inside an ergonomically designed mobile cart with a mains power cable. It also includes the Drive-motor and Optical Controller (DOC), which provides the interconnection between the ILUMIEN System and the Dragonfly Catheter. The cart is equipped with two display monitors (one for the console operator, and the other for the physician), as well as a keyboard and mouse.

The cart also contains an isolation transformer for electrical safety and includes two AO and PW USB Receivers which accept the distal intracoronary and proximal aortic pressure signals and status information from the AO Interface Unit and PressureWire® Aeris (K080813) respectively, and communicate the FFR data for display on the ILUMIEN system.

The Dragonfly OPTIS Imaging Catheter is a sterile, single-use intravascular catheter consisting of a catheter body external sheath and an internal rotating fiber optic imaging core. The external sheath serves two primary functions: 1) to facilitate placement of the device into the coronary artery and 2) to cover and protect the inner rotating fiber optic imaging core.

The inner rotating fiber optic imaging core emits near infrared light to the tissue and receives reflected light. It is driven by a stainless steel torque wire visible under fluoroscopy and pulled back through the window tube of the external sheath by the DOC. The emitted and returned reflected light are combined and processed by the ILUMIEN Optis System software to construct an OCT image. The patient is never exposed to moving parts as the external sheath completely covers the rotating imaging core.

AI/ML Overview

The provided text is a 510(k) summary for the Lightlab Imaging, Inc. ILUMIEN with Dragonfly OPTIS Imaging Catheter. It indicates that the device has been found substantially equivalent to a predicate device (Lightlab Imaging, Inc. ILUMIEN, K111200). However, the document does not contain specific acceptance criteria, reported performance metrics as a table, or details about patient studies for the new device's performance.

The document discusses performance testing in a general sense, noting that hardware/firmware are unchanged and that software verification/validation, as well as design verification/validation (bench testing), were conducted in compliance with FDA regulations. Crucially, it states: "The results of this testing conclude the software has met these requirements. Design verification and validation was also performed on the ILUMIEN and Dragonfly OPTIS Imaging Catheter in compliance with internal design control procedures which included bench testing. The results of this testing concludes the ILUMIEN and Dragonfly OPTIS Imaging Catheter is determined to be safe and effective and is substantially equivalent to the predicate ILUMIEN device."

This implies that the device meets safety and effectiveness requirements, demonstrating substantial equivalence to its predicate, but it does not provide a specific study with acceptance criteria and results. The 510(k) process is about demonstrating substantial equivalence to an already marketed device, not necessarily proving efficacy through new clinical trials with defined acceptance criteria for a novel device.

Therefore, many of the requested details are not available in the provided text.

Here is a summary of what can be extracted or inferred, and what is not available:

1. Table of acceptance criteria and the reported device performance

Not available in the provided text. The document states that testing was conducted and concluded the device is safe, effective, and substantially equivalent, but it does not specify quantitative acceptance criteria or detailed performance metrics. It refers to compliance with various electrical safety, EMI, laser safety, and DICOM standards, but these are compliance standards, not performance thresholds for clinical accuracy or diagnostic capabilities.

2. Sample size used for the test set and the data provenance

Not available in the provided text. The document mentions "bench testing" for design verification and validation but does not specify sample sizes or data provenance (e.g., country of origin, retrospective/prospective) for any test set that would evaluate clinical performance.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not available in the provided text. There is no mention of experts establishing ground truth for evaluating clinical performance. The testing described focuses on engineering compliance and bench tests.

4. Adjudication method for the test set

Not available in the provided text. As clinical performance testing with a ground truth established by experts is not described, an adjudication method is also not mentioned.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and the effect size

No, this was not done or at least not described in the document. The document does not mention any MRMC studies or human reader performance with or without AI assistance. The device is an imaging system and catheter, not an AI-based diagnostic tool that assists human readers in the way typically evaluated by MRMC studies.

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

Not explicitly described as such. The device is an imaging system that produces OCT images and FFR parameters for a physician's use. It's not an algorithm producing a diagnostic output without human interpretation. Its performance is evaluated mechanically and through software validation, as outlined in the general "performance testing" section, but not in terms of standalone diagnostic accuracy in a clinical sense.

7. The type of ground truth used

Not explicitly stated in a clinical context. For the engineering and software validation, the "ground truth" would be established by the specifications and expected behavior based on internal design control procedures and established standards (e.g., UL, IEC, DICOM, FDA regulations). For the "imaging" aspect, the ground truth would be the physical properties of the tested objects in bench experiments. No pathology or outcomes data is mentioned as ground truth.

8. The sample size for the training set

Not applicable/Not available. The document describes modifications and upgrades to an existing imaging system and catheter. It does not refer to a machine learning or AI model that would require a "training set" in the conventional sense. The "software has been upgraded to revision D.2," indicating software development and testing, but not machine learning training.

9. How the ground truth for the training set was established

Not applicable/Not available. As there's no mention of a machine learning training set, there's no information on how its ground truth would be established.

In summary: The provided 510(k) summary focuses on demonstrating substantial equivalence through compliance with standards, verification, and validation of hardware and software modifications. It does not include specific clinical studies with defined acceptance criteria or expert-adjudicated performance data for the new device. The conclusion of substantial equivalence is based on the updated device having the same fundamental technological characteristics and indications for use as the predicate, with performance verified through bench testing and software validation against engineering standards and internal design controls.

AI/ML Overview

This document describes the ILUMIEN OPTIS system with the Dragonfly OPTIS Imaging Catheter, focusing on its substantial equivalence to a predicate device rather than presenting a standalone study with detailed acceptance criteria and performance data in the format requested. Therefore, much of the specific information requested cannot be extracted directly from this document.

However, based on the provided text, I can infer and summarize what is available regarding performance testing and regulatory compliance.

Here's a breakdown of the information and what is not available:

1. Table of Acceptance Criteria and Reported Device Performance:

This document does not provide a table of specific acceptance criteria (e.g., sensitivity, specificity, accuracy for a diagnostic task or specific measurement tolerances) and corresponding reported device performance values. The performance testing section primarily lists compliance with general safety and electromagnetic compatibility standards, along with successful software verification/validation and design verification/validation through bench and pre-clinical animal testing. It concludes that the device is "safe and effective and is substantially equivalent to the predicate ILUMIEN OPTIS device," but no quantitative performance metrics against specific acceptance thresholds are provided.

Therefore, this section cannot be completed as requested based on the input document.

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

Test Set Description: The document mentions "bench testing and pre-clinical animal testing" as part of design verification and validation.
Sample Size: The sample size for these tests is not specified in the document.
Data Provenance: The document does not specify the country of origin of the data. It mentions "pre-clinical animal testing," indicating it's not human data. It's a "prospective" study in the sense that these tests were conducted to demonstrate performance for regulatory submission, but not a prospective clinical trial on human subjects.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

This information is not provided in the document. For animal testing, ground truth might be established by other imaging modalities or histological analysis performed by veterinary pathologists, but the document does not elaborate.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

This information is not provided in the document.

5. If a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was done, and the effect size of how much human readers improve with AI vs without AI assistance:

AI assistance: The document describes an "Ultrasonic pulsed echo imaging system" and an "Imaging Catheter" for Optical Coherence Tomography (OCT) and Fractional Flow Reserve (FFR) measurements. While these are advanced technologies, the document does not indicate that the device involves AI (Artificial Intelligence) or machine learning components that would assist human readers in image interpretation or diagnosis.
MRMC study: A comparative effectiveness study with human readers (with vs. without AI assistance) is not mentioned in the document.

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

The device is an imaging system (ILUMIEN OPTIS) and a catheter (Dragonfly OPTIS) that generates OCT images and FFR measurements for physician use. It's an "algorithm only" in the sense that the system calculates FFR and constructs OCT images without human intervention in that specific process, but the overall purpose is to provide information for a human physician's judgment. The document does not discuss a "standalone" performance evaluation of the algorithms for diagnostic accuracy independent of human interpretation in a clinical context.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

For the "pre-clinical animal testing," it's likely that invasive measures, histological analysis, or other validated imaging modalities would form the ground truth, but the document does not specify the type of ground truth used.

8. The sample size for the training set:

The document does not mention or describe a training set. This is typical for medical device submissions focused on substantial equivalence where the device performs a measurement or creates an image, rather than making a diagnostic prediction based on learned patterns from a large dataset. The "software verification and validation" indicates software testing, but not a "training set" in the machine learning sense.

9. How the ground truth for the training set was established:

Since a training set is not mentioned, this information is not applicable/provided.

Summary of available information regarding performance:

The document primarily states that the ILUMIEN OPTIS and Dragonfly OPTIS Imaging Catheter have undergone:

Electrical safety testing: Compliance with UL Standard No 60601-1, IEC 60601-1-2, EN 60601-1-2, IEC 60825-1, 21 CFR 1040.10, and CFR 47 FCC Part 15 Subpart B.
Software verification and validation: Conducted according to FDA regulations, standards, and guidance, concluding that the software met requirements.
Design verification and validation: Included "bench testing and pre-clinical animal testing" in compliance with internal design control procedures. The results led to the conclusion that the device is "safe and effective and is substantially equivalent to the predicate ILUMIEN OPTIS device."

Conclusion:

This 510(k) summary focuses on demonstrating substantial equivalence to a predicate device, as opposed to providing detailed results of a new clinical performance study with specific acceptance criteria and outcome metrics for diagnostic accuracy, sensitivity, or specificity. The performance testing described is primarily related to safety, software functionality, and engineering design validation, concluding with an overall statement of safety, effectiveness, and substantial equivalence. Specific quantitative performance against predefined acceptance criteria for clinical use or AI diagnostic capabilities is not detailed in this document.

AI/ML Overview

This document is a 510(k) summary for a medical device and thus does not contain the detailed acceptance criteria or a comprehensive study report with all the requested information for device performance. It primarily focuses on demonstrating substantial equivalence to a predicate device.

However, based on the provided text, here's what can be extracted and what is missing:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly present a table of acceptance criteria with specific quantitative thresholds nor directly report device performance against such criteria in a comparative table. Instead, it states that "Design verification and validation was also performed on the OPTIS Integrated System and Dragonfly OPTIS Imaging Catheter in compliance with internal design control procedures which included bench testing and pre-clinical animal testing. The results of this testing concludes the OPTIS Integrated System and Dragonfly OPTIS Imaging Catheter is determined to be safe and effective and is substantially equivalent to the ILUMIEN OPTIS predicate device."

This implies that the acceptance criteria were likely based on demonstrating equivalence to the predicate device's performance, as well as adherence to various safety and performance standards (e.g., IEC 60601 series for electrical safety, electromagnetic compatibility, and usability, and 21 CFR 1040.10 for light-emitting products). The performance reporting is qualitative, stating that the device is "safe and effective."

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

The document mentions "pre-clinical animal testing" but does not specify the sample size for this test set (e.g., number of animals, number of imaging procedures). It also does not provide the country of origin of the data or whether the study was retrospective or prospective.

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

This information is not provided in the document.

4. Adjudication Method for the Test Set

This information is not provided in the document.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No MRMC study is mentioned. The document focuses on showing substantial equivalence through design verification and validation, including bench and pre-clinical animal testing.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

The device is an imaging system (OCT and FFR), which inherently involves a human operator (physician) for interpretation and clinical decision-making. The document does not describe an "algorithm only" standalone performance study in the way one might for an AI diagnostic tool. Its performance would be evaluated in terms of image quality, FFR measurement accuracy, and overall system functionality as used by a human.

7. Type of Ground Truth Used

The document doesn't explicitly state the "type of ground truth" used for the pre-clinical animal testing. For imaging systems, ground truth in animal studies often involves:

Histopathology: Microscopic examination of tissue samples after imaging to correlate image findings with actual tissue structures.
Other established imaging modalities: Comparison with a gold standard imaging technique if available for the specific features being evaluated.
Direct observation/measurement: For functional parameters like FFR, comparison against direct pressure measurements.

Given the nature of OCT imaging for coronary arteries, histopathology or highly detailed anatomical measurements would likely be involved. For FFR, direct pressure transducer measurements during the animal study would serve as ground truth.

8. Sample Size for the Training Set

The document does not mention a "training set" in the context of machine learning or AI. While the device uses software, the context here is a medical imaging system, not a deep learning algorithm that typically requires a large training dataset. The software upgrades mentioned (e.g., Angio Co-Registration, Continuous calibration, improved acquisition workflow) likely involve traditional software engineering and validation processes rather than machine learning model training.

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

As no training set (in the AI/ML sense) is mentioned, this information is not applicable or provided. The software validation would have involved testing against requirements and specifications, rather than a "ground truth" derived from a large dataset for training.
