FLUOBEAM® LX and FLUOBEAM® LX Red are intended to provide real-time near infrared (NIR) fluorescence imaging of tissue during surgical procedures. Upon intravenous administration and use of an ICG consistent with its approved labeling, the FLUOBEAM® LX and FLUOBEAM® LX Red are indicated for use in capturing and viewing fluorescent images for the visualization of vessels, blood flow and tissue perfusion before, during and after organ transplant, plastic, micro- and reconstructive surgeries.
The FLUOBEAM® LX and FLUOBEAM® LX Red can also be used to assist in the imaging of parathyroid glands and can be used as an adjunctive method to assist in the location of parathyroid glands due to the auto-fluorescence of this tissue.
Use of the FLUOBEAM® LX and FLUOBEAM® LX Red devices are intended to assist, not replace, experienced visual assessment, and biopsy with conventional histopathological confirmation per standard of care. The system is not to be used to confirm the absence of parathyroid tissue or glands and is only to be used to assist in locating visually identified gland/tissues.

FLUOBEAM® LX and FLUOBEAM® LX Red enable surgeons to observe fluorescent images of parathyroid glands, blood vessels and related tissue perfusion. Fluorescence can be observed as a result of natural fluorescence of parathyroid glands or as a result of a fluorescent product, indocyanine green (ICG), injected intravenously into patients before the surgery allowing the perfusion assessment.
Class 1 infrared laser light is used to excite the fluorescent tissues of parathyroid glands or the ICG and illuminate the regions of a patient's body to be observed. A camera inside the optical head captures the fluorescent image that is used to visualize the parathyroid glands or assess the blood vessels and related tissue perfusion. FLUOBEAM® LX and FLUOBEAM® LX Red consist of the following components: a hardware part with a camera unit (optical head) linked by a specific cable to a control box and a software part with FLUOSOFT™ LX or FLUOSOFT™ LX Red imaging software. The optical head contains a video camera and light sources (laser and LEDs) and is used by hand. The control box receives the video signal of the fluorescent image from the optical head, it digitizes it and sends it to a computer that outputs it on a display screen and/or records it. Adjustments of the fluorescent image are possible either by the optical head or via the FLUOSOFT™ LX imaging software and the FLUOSOFT™ LX Red imaging software on the computer.
This special 510(k) premarket notification is intended to re-frame the indications for use statement to be consistent with specific indications of legally marketed ICG products, eliminating the need for the co-packaging with ICG.
The provided document is a 510(k) Premarket Notification from the FDA, specifically concerning a "Special 510(k)" for the FLUOBEAM® LX and FLUOBEAM® LX Red Imaging Systems.
Crucially, this document states: "No performance data are needed to support the modified indications for use. As noted above, there are no technological changes associated with the proposed labeling changes. Additionally, no new surgical procedures or tissue types are being referenced in the modified indications for use."
This means the submission is not presenting new performance studies or data to demonstrate the device meets acceptance criteria. Instead, it's leveraging the substantial equivalence to previously cleared devices (K190891 and K230898) and a reference device (K223020) because the changes are limited to refining the "Indications for Use" statement to align with existing ICG product labeling, thereby eliminating the need for co-packaging with ICG.
Therefore, for the information requested in your prompt, based solely on the provided text, we cannot fill in most of the table or answer many of the questions as no new performance study data is presented.
Here's what can be extracted from the document:
1. Table of acceptance criteria and the reported device performance:
| Acceptance Criteria (Not explicitly stated as such for new performance, but implied by substantial equivalence to predicates) | Reported Device Performance (Implied by substantial equivalence to predicates) |
|---|---|
| Ability to provide real-time near infrared (NIR) fluorescence imaging of tissue during surgical procedures. | Device provides real-time NIR fluorescence imaging. |
| Visualization of vessels, blood flow and tissue perfusion with ICG. | Device enables visualization of vessels, blood flow, and tissue perfusion with ICG. |
| Assistance in imaging parathyroid glands and location due to auto-fluorescence. | Device assists in imaging and locating parathyroid glands through auto-fluorescence. |
| Consistent with the performance of predicate devices FLUOBEAM® LX (K190891) and FLUOBEAM LX Red (K230898). | Device performance is substantially equivalent to predicate devices. |
2. Sample size used for the test set and the data provenance:
- Sample size: Not applicable, as no new performance study data is presented. The submission relies on substantial equivalence.
- Data provenance: Not applicable.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable, as no new performance study data is presented.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- Not applicable, as no new performance study data is presented.
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/CADe/CADx device that assists human readers in interpretation or diagnosis. It aids in visualization during surgery. No MRMC study is mentioned.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is not an algorithm-only device; it's an imaging system where a human observes the generated images.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- Not explicitly stated for new data, as none was required. For the original clearance of the predicate devices, ground truth would likely have involved direct visual confirmation during surgery, correlation with anatomical knowledge, and potentially histopathological confirmation where applicable (e.g., for parathyroid tissue). The document reiterates that the device "is not to be used to confirm the absence of parathyroid tissue or glands and is only to be used to assist in locating visually identified gland/tissues," implying that standard clinical and pathological evaluations remain the definitive ground truth for such aspects.
8. The sample size for the training set:
- Not applicable, as no new performance study data for a machine learning model is presented.
9. How the ground truth for the training set was established:
- Not applicable, as no new performance study data for a machine learning model is presented.
In summary: This 510(k) submission primarily focuses on a labeling change for an existing device, asserting that no new performance data is needed because "there are no technological changes associated with the proposed labeling changes. Additionally, no new surgical procedures or tissue types are being referenced in the modified indications for use." Therefore, the detailed performance study information requested is not present in this specific FDA clearance document.
