Abstract A method is provided of treating cutaneous vascular lesions in a target area of a patient. The method comprises the steps of passing a laser beam against and through a cooling medium, and then passing the laser beam against and through a patient's epidermis to the target area while simultaneously subjecting the patient's epidermis to a cooling medium at the location of the epidermis entered by the laser beam. An apparatus for treating a cutaneous vascular lesion in a target area of a patient comprises a laser beam source for directing a laser beam against and through a predetermined location of an epidermis of the patient to the target area and a flexible bag for containing a cooling medium and for subjecting the patient's epidermis to the cooling medium at the target area simultaneous with the application of the laser beam thereto. The flexible bag is positioned between the laser beam source and the target area of the patient's epidermis.
A method of treating cutaneous vascular lesions in a target area of a patient, said method comprising the steps of: positioning a cooling medium contained in a closed container having a pair of walls adjacent a location of an epidermis of the patient, and positioning a laser beam adjacent the container; passing the laser beam through one of the pair of walls of the container and then through the cooling medium contained in the container; then passing the laser beam through the other of the pair of walls of the container; and thereafter passing the laser beam through the location of the epidermis of the patient to the target area while simultaneously subjecting the location of the epidermis to the cooling medium.
