Abstract

The present disclosure relates generally to fluorescent imaging devices, systems, and methods for an endoscopic procedure, and in particular, indocyanine green (ICG) fluorescence. In some embodiments, a device for fluorescent imaging during an endoscopic procedure may include an attachment connectable to a distal end of an endoscope. The attachment may include a first filter alignable with a light source of the endoscope, and a second filter alignable with an imaging device of the endoscope. The first filter may be positionable such that in a first position the first filter is aligned with the light source, and in a second position the first filter is out of alignment with the light source. The second filter may be positionable such that in a first position the second filter is aligned with the imaging device, and in a second position the second filter is out of alignment with the imaging device.
