An apparatus for treating adipose tissue located beneath a patients skin includes a main body portion that houses an ultrasound transducer that outputs transverse ultrasound waves to be applied to a patients skin. The apparatus also includes a semisphere portion provided at a distal end of the apparatus and that is configured to contact the patients skin when the patient is being treated with the apparatus. The apparatus further includes an intermediate portion provided between the main body portion and the semisphere portion, in which a connector that provides the ultrasound waves from the ultrasound transducer to the semisphere portion is housed. The intermediate portion is disposed substantially perpendicular to the main body portion. An embodiment composed by two apparatus connected back to back in order to eliminate vibrations and emission of longitudinal waves in direction perpendicular to the skin.
