Abstract
The invention discloses a method and a device to treat vessels. In particular, the invention is directed at a method to occlude varicose veins while avoiding the formation of bubble clouds in the tissue surrounding the vessel and/or their interaction with the ultrasound beam. The invention is further directed at a device adapted to perform the method.
Claims7
A method for treatment of a vein by a HIFU beam having a focal spot, the HIFU beam being emitted by a treatment head, comprising positioning the treatment head so that a center of the focal spot is positioned or positionable deeper than a center of the vein, and further emitting a HIFU pulse with the center of the focal spot being deeper than the center of the vein, and further so that an upper boundary of the focal spot is at or deeper than an upper boundary of the vein, so that a creation of bubbles in a first tissue located between the treatment head and the vein is avoided or limited during the emission of the HIFU pulse.
