AI/ML Overview

The provided text is a 510(k) Premarket Notification summary for the Cellvizio® I.V.E. system with Confocal Miniprobes™. This submission is primarily to extend the device's Indications for Use to include imaging blood flow in vascular areas when used with Fluorescein Sodium as a contrast agent.

Based on the document, here's a breakdown of the requested information:

1. A table of acceptance criteria and the reported device performance

The document does not explicitly state "acceptance criteria" for performance metrics in a quantitative manner (e.g., sensitivity, specificity, accuracy thresholds). Instead, the submission relies on demonstrating substantial equivalence to previously cleared devices. The "performance" assessment is based on the device having the "same intended use," "same operating principle," "same technological characteristics," "same design," and "same biocompatible materials" as predicate and reference devices, especially in the context of the new expanded indication.

Therefore, the "acceptance criteria" are implied to be equivalence to the performance of the predicate and reference devices under the expanded use case (imaging blood flow with Fluorescein Sodium), as the core technology and hardware are unchanged.

Acceptance Criteria (Implied by Substantial Equivalence)Reported Device Performance and Justification
Similar Intended Use and Indications for Use (especially with Fluorescein Sodium)Subject Device: The Cellvizio® I.V.E. system with Confocal Miniprobes™ is indicated for imaging blood flow in vascular areas, including microvasculature and capillaries when used with Fluorescein Sodium. Predicate Device (K191144): The Cellvizio® 100 Series system with Confocal Miniprobes™ with Fluorescein also has identical Indications for Use including blood flow visualization in vascular areas, including microvasculature and capillaries with Fluorescein Sodium. Justification: "Identical Indications for Use... including blood flow visualization in vascular areas, including microvasculature and capillaries with Fluorescein Sodium."
Similar Operating Principle & Technological CharacteristicsSubject Device: Confocal laser scanning system with fiber optic probe. Predicate and Reference Devices: Also confocal laser scanning system with fiber optic probe. Justification: "has the same operating principle, the same technological characteristics, and the same design."
Similar Hardware Design (Laser, Detection, Scanning, Display, etc.)All key hardware attributes (Laser source, Physical Method of Illumination, Physical Method of Imaging, Laser classification, Scanning system technology, Illumination output, Detection Bandwidth, Location of Signal Detection/Conversion/Processing, Fluorescence Excitation) are stated to be "Same" or "Same technology" as the predicate and reference devices. Justification: "The subject device... is exactly the same device in terms of design and performance as the previously cleared device (K193416)."
Similar Software/Firmware (Image Processing, Control)Firmware algorithm and Image processing algorithm are stated to be "Same functions with equivalent algorithm" or "Same algorithm with addition of automatic adjustment of laser focus in the fiber bundle" (which is a refinement, not a fundamental change). Justification: Found substantially equivalent (cleared via K193416).
Safety Data (Biocompatibility, Laser Safety)Justification: "constructed with the same biocompatible materials and meets the same biocompatibility tests requirements"; "Same maximum laser output and therefore no additional testing was performed to ensure safety."
Co-packaging (with Fluorescein Sodium)Justification: "Confocal Miniprobes™ model will be delivered co-packaged with Sodium Fluorescein vials in an identical way as the one described and cleared in K191144." "No additional testing was performed for the co-packaging of Sodium Fluorescein with Cellvizio® I.V.E the Confocal Miniprobes™."

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

The document explicitly states: "As no technical change is being made to the subject/reference device, all testing required has been provided in the previous submission (K193416)." And further, regarding co-packaging: "Therefore, no additional testing was performed for the co-packaging of Sodium Fluorescein with Cellvizio® I.V.E the Confocal Miniprobes™."

This indicates that no new clinical study or test set data was generated for this specific 510(k) submission (K212322). The basis for substantial equivalence is the prior clearance of the Cellvizio® I.V.E. system (K193416 as a reference device) and the Cellvizio® 100 Series system with Fluorescein (K191144 as a predicate device). The document does not provide details about the sample sizes or data provenance (e.g., country of origin, retrospective/prospective) of the studies that supported those previous clearances.

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

Since no new human reading study or clinical test set was conducted for this submission (K212322), this information is not provided. The substantial equivalence argument relies on the inherent capabilities of the device, which were previously established and deemed safe and effective in earlier clearances.

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

Not applicable, as no new clinical study or human reading test set was conducted for this submission.

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 an imaging system, not an AI-assisted diagnostic tool for human readers, and no MRMC study was performed for this submission.

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

This refers to the performance of the device itself as an imaging system. The "performance" is demonstrated through its physical and optical characteristics (e.g., field of view, depth of observation, lateral resolution, real-time image visualization frequency), which are stated to be "Same" as previously cleared devices. The document essentially argues that the device's technical specifications and resulting image quality are equivalent to the predicate and reference devices, implying equivalent "standalone" performance. No new quantitative performance metrics (like accuracy against a ground truth for a specific disease) are presented as part of this submission.

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

For this specific 510(k), since the submission is based on substantial equivalence to existing devices and expanding an indication for an existing capability (blood flow imaging with a contrast agent), no new ground truth establishment is detailed. The performance of confocal endomicroscopy in general (the technology this device uses) is inherently about visualizing microstructures and blood flow. The "truth" would logically be the real-time images themselves, and in a clinical context, a physician's interpretation of those images in conjunction with other diagnostic information. For the original clearances of the predicate and reference devices, ground truth for imaging capabilities would typically involve:

  • Physical/Optical Measurements: Demonstrating adherence to specifications for resolution, field of view, depth of observation.
  • Bench Testing/Phantom Studies: Using known physical models to assess image quality.
  • Pre-clinical (animal) and Clinical Studies: Demonstrating the ability to visualize the intended structures (cells, vessels, blood flow) in vivo, often compared to histological confirmation or other established imaging modalities if applicable to the initial clearances.

8. The sample size for the training set

Not applicable. This submission is for an imaging device, not an AI/machine learning algorithm requiring a "training set."

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

Not applicable, as there is no AI algorithm being trained for this submission.

As described in K193416, the cleared Cellvizio® I.V.E. system and its Confocal Miniprobes™ represent a refinement to Cellvizio® 100 series system and its Confocal Miniprobes™ (K172844). Design modifications and refinements included:

  • Improving the integration of the system in endoscopy, interventional, or surgical operating 1. suites by reducing the global footprint of the system.
  • Improving the user interface and ease-of-use of the system by replacing the keyboard and 2. the trackball of the Cellvizio® 100 series with a touchscreen for review and interaction with the software and the addition of a separate remote (external) display screen for live imaging. This configuration allows better positioning of the physician's line of site during procedures.
    1. Simplifying the connection of the Miniprobes to the system. This improvement has no impact on other parts of the Confocal Miniprobe design, in particular the sheathed fiber and the distal head that are the patient-contacting parts are unchanged.
    1. The addition of "autofocus," allowing automatic positioning of the laser focal point for optimal optical injection from the Optical Scanning Unit into the fibers.

The subject device. the Cellvizio® I.V.E. system (with Confocal Miniprobes™) used with Fluorescein Sodium Contrast Agent) has the same intended use and indication for uses than the predicate device (the Cellvizio® 100 Series system (with Confocal Miniprobes™) since both devices are intended to be used to image the tissue microstructures and blood flow in vascular areas, including microvasculature and capillaries when used in combination with Fluorescein Sodium dye. The subject device is similar in terms of design to the cleared predicate device as it:

  • . has the same operating principle, the same technological characteristics, and the same design:
  • is constructed with the same biocompatible materials and meets the same ● biocompatibility tests requirements;
  • is reprocessed with the same methods; ●

{9}------------------------------------------------

  • . has the same device packaging with a co-packaging with Sodium Fluorescein.
    The subject and predicate devices, when used in combination with Sodium Fluorescein dye, have the same intended use and indications for use. The differences between subject device, the Cellvizio® I.V.E. system with Confocal Miniprobes™ and the predicate device (K191144), including revisions to the User Interface, System footprint and Connector can have no effect upon the system's ability to be used with Sodium Fluorescein and the imaging of blood flow indication. The Cellvizio® I.V.E. system, in the exact same manner as K191144, can be used to examine blood flow in vascular areas, including microvasculature and capillaries.
