Intended Use

The Endoscope Module of the VS3-IR-MMS System is intended for viewing internal surgical sites during general surgical procedures, for use in visualization of ventricles and structures within the brain during neurological surgical procedures, viewing internal surgical sites during anterior spinal procedures, such as nucleotomy, discectomy, and foraminotomy, and shoulder and knee arthroscopic procedures. The Iridium Module of the VS3-IR-MMS System is intended for capturing and viewing fluorescent images for the visual assessment of blood flow, as an adjunctive method for the evaluation of tissue perfusion, and related tissue-transfer circulation in tissue and free flaps used in plastic, micro- and reconstructive surgical procedures.

Device Description

The VS3-IR-MMS System consists of the cleared base system and the Iridium Module that is the subject of this submission. The currently marketed VS3 system with endoscope functionality was cleared under the following product codes: GCJ (General Surgery Endoscope), GWG (Neurological Endoscope), and HRX (Orthopedic Arthroscope). The cleared base system consists of the following components and accessories: High Definition 3D Endoscope, High Definition 3D Camera with 3 control buttons and a focus adjustment knob, 2D Coupler, CCU, Light Source, and Display Monitor. The VS3-IR-MMS System that is the subject of this submission contains the previously cleared components of the cleared base system listed above, as well as a High Definition IR Fluorescence Scope (MMS), a Laser Light Source (LLS), associated software and VS, Iridium IR Fluorescence Kit. The new Iridium Module, which uses the newly added High Definition IR Fluorescence Scope (MMS) and a Laser Light Source (LLS), as well as the cleared High Definition 3D Camera, Camera Control Unit (CCU), and Display Monitor, is used to generate florescence excitation illumination for external use in capturing and viewing fluorescent images for the visual assessment of blood flow, as an adjunctive method for the evaluation of tissue perfusion, and related tissue-transfer circulation in tissue and free flaps used in plastic, micro- and reconstructive surgical procedures.

AI/ML Overview

The document describes the VS3-IR-MMS System and its Iridium Module, which is intended for capturing and viewing fluorescent images for the visual assessment of blood flow as an adjunctive method. The submission focuses on demonstrating substantial equivalence to a predicate device, the Novadaq Technologies SPY Imaging System (K063345), rather than setting specific performance acceptance criteria for the new module.

Here's an analysis of the provided information regarding acceptance criteria and the study:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state quantitative acceptance criteria for the Iridium Module's performance in terms of metrics like sensitivity, specificity, or accuracy. Instead, it relies on demonstrating that the device "functions as intended" and "met all performance acceptance criteria" based on bench testing and limited human subject evaluations. The primary "acceptance criteria" presented are related to regulatory standards compliance and functional equivalence to the predicate.

Acceptance Criteria (Implied)Reported Device Performance

Emission Band is 825nm to 850nm825nm to 850nm
Emission Capture using IR cameraIR camera

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

  • Bench Testing:
    • ICG in sterile water: A single sample of 10mg ICG diluted to 2 ug/ml.
    • ICG through chicken skin: A single sample of ICG in sterile water covered with chicken skin.
  • Human Simulation: A human hand was used. (Sample size: 1)
  • Human Subjects: "Several human subjects" were evaluated in free flaps. (Exact sample size not specified, but implied to be small).
  • Data Provenance: The human hand simulation and human subject evaluations were conducted "outside of the United States." The context suggests these were prospective evaluations, albeit limited.

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

The document does not specify the number or qualifications of experts used to establish ground truth for the test sets. The interpretations of "good quality imaging" during bench testing and "functions as intended" or "no adverse events" during human evaluations were likely made by the researchers or clinical personnel involved in the studies, but their specific expert qualifications are not detailed.

4. Adjudication Method for the Test Set

The document does not mention any formal adjudication method (e.g., 2+1, 3+1) for evaluating the test results. The assessment appears to be based on direct observation and qualitative judgment by the study personnel.

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

No MRMC comparative effectiveness study was done. This device is not described as an AI-powered diagnostic or assistive tool for human readers in the traditional sense. It's an imaging system for visualizing blood flow.

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

The device is an imaging system; it captures and displays images for human interpretation. The concept of "standalone algorithm only" performance, as it applies to AI/ML diagnostic tools, is not relevant here. The system's function is to provide the visual information.

7. The Type of Ground Truth Used (Expert Consensus, Pathology, Outcomes Data, etc.)

  • Bench Testing: The ground truth was the known presence and concentration of ICG and the physical setup (ICG solution, ICG under chicken skin). Visual assessment of "good quality imaging" was the outcome.
  • Human Simulation (Hand): The ground truth was the expected blood flow in a human hand after ICG administration. Visual assessment of corresponding dye fluorescence was the outcome.
  • Human Subjects (Free Flaps): The ground truth was the actual tissue perfusion and related tissue-transfer circulation in free flaps. The assessment was that the device visualized blood flow and "functions as intended with no adverse events reported." This implies clinical observation of actual perfusion.

8. The Sample Size for the Training Set

No information is provided about a "training set" for the Iridium Module. The document describes a system with specific optical and imaging characteristics, not a machine learning model that requires a training set. The software modifications mentioned are likely for instrument control and image processing, not for AI model training.

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

As no training set is mentioned in the context of machine learning, this question is not applicable.

Intended Use / Indications for Use

The Endoscope Module of the VS3-IR-MMS System is intended for viewing internal surgical sites during general surgical procedures, for use in visualization of ventricles and structures within the brain during neurological surgical procedures, viewing internal surgical sites during anterior and posterior spinal procedures, such as nucleotomy, discectomy, and foraminotomy, and shoulder and knee arthroscopic procedures. The Iridium Module of the VS3-IR-MMS System is intended for capturing and viewing fluorescent images for the visual assessment of blood flow, as an adjunctive method for the evaluation of tissue perfusion, and related tissue-transfer circulation in tissue and free flaps used in plastic, micro- and reconstructive surgical procedures.

Technological Characteristics / Principles of Operation

The VS3-IR-MMS System consists of the cleared base system and the Iridium Module that is the subject of this submission. The currently marketed VS3 system with endoscope functionality was cleared under the following product codes: GCJ (General Surgery Endoscope), GWG (Neurological Endoscope), and HRX (Orthopedic Arthroscope). The cleared base system consists of the following components and accessories: High Definition 3D Endoscope, High Definition 3D Camera with 3 control buttons and a focus adjustment knob, 2D Coupler, CCU, Light Source, and Display Monitor. The VS3-IR-MMS System that is the subject of this submission contains the previously cleared components of the cleared base system listed above, as well as a High Definition IR Fluorescence Scope (MMS), a Laser Light Source (LLS), associated software and VS, Iridium IR Fluorescence Kit. The new Iridium Module, which uses the newly added High Definition IR Fluorescence Scope (MMS)

{4}------------------------------------------------

and a Laser Light Source (LLS), as well as the cleared High Definition 3D Camera, Camera Control Unit (CCU), and Display Monitor, is used to generate florescence excitation illumination for external use in capturing and viewing fluorescent images for the visual assessment of blood flow, as an adjunctive method for the evaluation of tissue perfusion, and related tissue-transfer circulation in tissue and free flaps used in plastic, micro- and reconstructive surgical procedures.

In sum, the proposed VS3-IR-MMS System is built on the predicate base VS3 System that has already been cleared for the treatment of viewing internal surgical sites during general surgical procedures and for use in visualization of ventricles and structures within the brain during neurological surgical procedures, viewing internal surgical sites during anterior and posterior spinal procedures, such as nucleotomy, discectomy, and foraminotomy, and shoulder and knee arthroscopic procedures (see K123467. K131434. K141002). The Iridium Module added to the cleared base system results in the following changes to the cleared system:

  • . Addition of a new scope ("MMS"), which is intended to provide a view of the surgical field from 20cm to 45cm above the patient.
  • . Addition of a Laser Light Source ("LLS") used to generate florescence excitation illumination.
  • Software modifications to allow the new MMS with LLS to be used with the cleared system.
  • Addition of the VS, Iridium IR Fluorescence Kit which contains the sterile ICG imaging agent used for fluorescence imaging.
  • . Additional indications for use with the new Iridium Module, which includes the MMS with LLS and associated software (described above) to include capturing and viewing fluorescent images for the visual assessment of blood flow, as an adjunctive method for the evaluation of tissue perfusion, and related tissue-transfer circulation in tissue and free flaps used in plastic, micro- and reconstructive surqical procedures.

The Iridium Module that is the subject of this submission is designed to work with the Indocyanine Green (ICG) IR fluorescence imaging agent supplied in the VSg Iridium IR Fluorescence Kit. Each VS . Iridium IR Fluorescence Kit contains the following:

  • o Six 25mg vials of sterile ICG imaging agent.
  • o Six 10ml vials of sterile Water for Injection.

ICG in blood has maximum excitation at 805nm and an emission band between 825nm and 850nm. VS, Iridium Module provides excitation light to the surgical field to excite the dye molecules and captures emission from the dye using an IR camera.

The VS3-IR-MMS System permits recording surgical procedures, storing them on removable storage devices, and plaving the procedures back.

The system software was validated and performs as intended per the pre-specified requirements.

In addition, bench testing was conducted to verify that the subject device can detect and visualize anatomy and blood flow per the proposed indications for use of the Iridium Module. Specifically, 10mg of ICG was dilated in sterile water to a concentration equal to that of ICG in the blood of a representative human (i.e., 2 ug/ml). Next, the ICG in sterile water diluted to representative human concentration was imaged directly to verify good quality imaging. Then, the sample of ICG in sterile water diluted to representative human concentration was covered with chicken skin and imaged to simulate visualization through skin.

On a related note, outside of the United States, a human hand was used in a simulated use testing environment to demonstrate that the Iridium Module has the capability to visualize blood flow corresponding to ICG dye fluorescence of blood vessels in the skin.

Lastly, an evaluation of the device was performed in free flaps in several human subjects outside the US and demonstrated that the device functions as intended with no adverse events reported using the system.

In all instances, the VS3-IR-MMS System using the Iridium Module functioned as intended and met all performance acceptance criteria.

Substantial Equivalence

The endoscope functionality of the base VS3-IR-MMS System was previously cleared. The proposed Iridium Module of the VS3-R-MMS has the same intended uses and similar indications, technological characteristics, and principles of operation as its predicate device (K063345). The minor technological differences between the VS3-IR-MMS System Iridium Module and its predicate device do not raise different questions of safety or effectiveness. Performance data demonstrate that the VS3-IR-MMS System Iridium Module is as safe and effective as the predicate device. Thus,

{6}------------------------------------------------

the VS3-IR-MMS Iridium Module is substantially equivalent. See the below comparison table of the Iridium Module of the updated VS3-IR-MMS and the Novadaq Spy Imaging device (K063345).
