IC-Flow™ Imaging System, is Diagnostic Green’s CE approved imaging camera. It is a small, compact and easy to use handheld device used to visualise and record tissue fluorescence. The IC-Flow™ Imaging System is a medical infrared camera for viewing fluorescent images of ICG dye in the patient’s body.
Yes, in March 2016 the IC-Flow™ Imaging System received its CE mark approval as a Medical Device Class I.
The intended use is as an imaging system, used 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-reconstructive surgery, and organ transplant procedures. The device is used by surgeons or trained health care professionals within a doctor’s office environment and in hospital settings.

The IC-Flow™ Imaging System provides for the visualisation of the distribution and intensity of a fluorescent dye, Indocyanine Green (Verdye, ICG) in human tissue.

Indocyanine Green, ICG is reconstituted and injected. Through the use of the IC-Flow™ Imaging System, a near-infrared light is exhibited. The LED light source excites the Indocyanine Green, ICG molecules in the tissue and the Indocyanine Green ICG emits fluorescence.

The fluorescent light of ICG is detected by the camera filters and images or videos are displayed on a monitor and/or touch screen.
