DEVICE FOR DELIVERING ELECTROMAGNETIC RADIATION TO HUMAN TISSUE

摘要

The present invention discloses a device for delivering electromagnetic radiation (3) to human tissue. The device comprises a treatment head with a duct (5) that is fillable with liquid (6). Radiation is coupled into the liquid. The liquid is ejected through a nozzle (13) as a jet (14), guiding the radiation through total internal reflection. The device allows a safer guidance of the radiation towards the skin etc., and furthermore allows a much larger depth of field, i.e. the distance over which the radiation may be delivered effectively.
