Enhanced Views in Bypass and AVM Surgeries with Fluorescent Filters

See more and make decisions with more confidence

Leica Microsystems is a pioneer in the field of fluorescence microscopy technology, developing innovative fluorescent modules for various medical applications. Our TriFluoro filter concept enables up to three modes of integrated fluorescence:

FL560 fluorescence filter: Get a single, real-time view of fluorescent and non-fluorescent areas with clear differentiation and high contrast during aneurysm repair.
FL400 fluorescence filter*: When used with 5-aminolevulinic acid (5-ALA) this filter supports resection procedures by allowing precise differentiation of tumor tissue from healthy brain tissue.
FL800 intraoperative video-angiography module: When used in conjunction with ICG fluorescent dye, this feature allows neurosurgeons to clearly visualize blood flow in real-time.

*Please check with your local Leica Microsystems representative for product registration status.
