INFRARED 800 with FLOW 800 Option is a surgical microscope accessory intended to be used with a compatible surgical microscope in viewing and visual assessment of intraoperative blood flow in cerebral vascular area including, but not limited to, assessing cerebral aneurysm and vessel branch occlusion, as well as patency of very small perforating vessels. It also aids in the real-time visualization of blood flow and visual assessment of vessel types before and after Arteriovenous Malformation (AVM) surgery. Likewise, INFRARED 800 with FLOW 800 Option used during fluorescence guided surgery aids in the visual assessment of intra-operative blood flow as well as vessel patency in bypass surgical procedures in neurosurgery, plastics and reconstructive procedures and coronary artery bypass graft surgery.
YELLOW 560 is a surgical microscope accessory intended to be used with a compatible surgical microscope in viewing and visual assessment of intraoperative blood flow in cerebral vascular area including, but not limited to, assessing cerebral aneurysm and vessel branch occlusion, as well as patency of very small perforating vessels. It also aids in the real-time visualization of blood flow and visual assessment of vessel types before and after Arteriovenous Malformation (AVM) surgery.
