Patent ID: 8579835

Claim:
A device for treating adipose tissue located beneath a patient's skin, the device comprising: a) a sonotrode including a proximal portion, a distal portion, and an elongated neck portion connecting the proximal portion to the distal portion, the sonotrode being dimensioned such that: (i) a ratio between a dimension of the neck portion parallel to an elongate axis of the neck and a dimension of the neck portion perpendicular to the elongate axis of the neck is at least 1.5; (ii) a ratio between a dimension of the distal portion perpendicular the elongate axis of the neck and a dimension of the distal portion parallel to the elongate axis of the neck is at least 2; (iii) a ratio between a dimension of the proximal portion perpendicular to the elongate axis of the neck and the dimension of the neck portion perpendicular to the elongate axis of the neck is at least 2.5; and (iv) a ratio between the dimension of the distal portion perpendicular to the elongate axis of the neck and the dimension of the neck portion perpendicular to the elongate axis of the neck is at least 2; and b) an ultrasound transducer, wherein the ultrasound transducer is operatively coupled to the proximal portion of the sonotrode and induces ultrasound vibrations in the distal portion.
