Abstract
In a device for treating blood vessels with a laser, the laser provides a beam in a wavelength range from 750 to 850 nm, preferably 805 nm. The device has a measuring unit which measures the concentration of a chromophore (preferably indocyanine green) administered to the patient in the patient's blood vessels. The device further comprises a control unit which controls the power of the laser in a contrary sense to the measured concentration.
