There is no mention of AI, ML, deep learning, or any related terms, nor is there a description of training or test sets for an AI/ML model. The focus is on the optical and signal processing aspects of the camera system.
No
The device is described as an "adjunctive monitor" for oxygen saturation and is explicitly stated that "The prospective clinical value of measurements made with OSI has not been demonstrated in disease states" and "BLI and LCI are not intended to replace histopathological sampling as a means of diagnosis." This indicates it's for observation and diagnosis, not direct treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is "used for endoscopic observation, diagnosis, treatment, and image recording."
No
The device description explicitly states it is comprised of a Camera Control Unit and a Camera Head, which are hardware components.
Based on the provided information, the SCHOELLY Oxygen Saturation Imaging (OSI) Camera System is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The SCHOELLY OSI Camera System is used for endoscopic observation, diagnosis, treatment, and image recording within the body. It processes signals from a fiberoptic endoscope and provides real-time visualization of tissue oxygen saturation.
- Sample Type: The device does not analyze samples taken from the body. It directly images and analyzes tissue in situ.
Therefore, while it is a medical device used for diagnosis and monitoring, it does not fit the definition of an In Vitro Diagnostic.

BLI (Blue Light Imaging) and LCI (Linked Color Imaging) are adjunctive tools which can be used to supplement white light endoscopy. BLI and LCI are not intended to replace histopathological sampling as a means of diagnosis. The SCHOELLY OSI Camera System is further intended for use as an adjunctive monitor of the hemoglobin oxygen saturation of blood in superficial tissue of the endoscopic observation image area in patients at risk for ischemic states. The prospective clinical value of measurements made with OSI has not been demonstrated in disease states.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Reprocessing validation: Reprocessing validations were designed and conducted in accordance with FDA's Guidance Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling (March 2015, including Appendix E revised June 2017). Cleaning and sterilization studies were designed and performed in accordance with ANSI/ AAMI ST98:2022 and ISO 14937:2009. Cleaning and sterilization processes are defined in the device labeling as per ISO 17664:2017. These tests demonstrated that the device successfully passed cleaning and sterilization validations according to the instructions in the user manual.
Electrical Safety and Electromagnetic Compatibility Testing: The OSI Camera System was assessed for conformity with, and was found to comply with the relevant requirements of IEC 60601-1:2005+AM1:2012, IEC 60601-1-2:2014, IEC 60601-1-2:2020, and IEC 60601-2-18:2009.
Non-Clinical Performance Testing: Non-clinical testing of the proposed device's imaging modes was conducted with its WLI, BLI and LCI modes to assess image sharpness, depth of field, signal-to noise ratio, temporal noise, color reproduction, dynamic range, distortion, contrast enhancement, and The results showed that the device could accurately reproduce reference artifacts. OSI testing included measurements regarding oxygen saturation accuracy, the effect of distance, angle and orientation, and the effect of temperature and duration, as well as the measurement of two-dimensional StO2 variation. The proposed SCHOELLY OSI Camera System and the primary predicate device's output were compared to the reference device with measurements on a tissue phantom with controlled oxygen levels. The results showed that the oxygen saturation values produced by the SCHOELLY device were similar to those produced by the primary predicate. Images of the human oral cavity and hand were also acquired to provide a side-by-side comparison of the SCHOELLY OSI mode and the primary predicate device's oximetry mode. The results demonstrated that the SCHOELLY OSI Camera System produced similar images compared to predicate device. In addition, comparisons of intestines and stomach images from an in-vivo animal study were made for the WLI, BLI, LCI, and OSI modes, and the comparisons showed that the SCHOELLY device produced images that were similar to those produced by the primary predicate device. The combination of bench testing and results from in-vivo animal and human testing support that the SCHOELLY device can produce images of similar intensity, color, contrast, and tissue oxygenation, compared to those produced by the primary predicate device and the results support substantial equivalence.
