FDA has cleared a Leica Microsystems 510(k) for its FL560 fluorescence microscope filter for visualizing cerebrovascular blood flow in conjunction with the dye fluorescein. “When integrated into a M530 OH6 neurosurgical microscope, FL560 fluorescence provides real-time, high-contrast visualization of both cerebral anatomy in native color and fluorescent blood flow,” the company says. This combined view gives surgeons more information to aid assessment and decision-making during vascular neurosurgery, it says.
