Intraoperative Fluorescence-Guided Aspirate Tissue Monitoring of 5-ALA During Brain Tumor Surgery

A medical device (HIVEN®) detects 5-ALA-induced fluorescence from the surgical suction and gives sound feedback to the operating surgeon indicating tumor tissue and overcoming the challenges is the contemporary FGS methods. The device is used for detecting fluorescence of flowing tissues within a transparent tube and providing auditory feedback of tissue fluorescence for neurosurgeons. There is no patient contact intended with this device.
