Multiwavelength ultrasonic tissue treatment apparatus

Abstract

An apparatus for the treatment of skin tissue includes at least one ultrasound transducer for placement on the skin tissue surface; at least two drivers for driving the at least one transducer; a controller which is configured to control the at least two drivers; the controller is configured to drive the at least two drivers at different frequencies to affect different depths in the skin tissue.

         18 . Apparatus for the treatment of skin tissue comprising:
 two ultrasound transducers for placement on the skin tissue surface;   one or more drivers for driving the two transducers;   a controller configured to control the one or more drivers;   wherein the two transducers are angled with respect to the tissue surface towards one another such that, when activated by the programmable controller, ultrasound energy delivered to the skin tissue by the two transducers is superimposed.   
     
     
         19 . The apparatus of  claim 18 , wherein one of the two transducers delivers ultrasound energy at an angle X relative to the skin tissue, and the other of the two transducers delivers ultrasound energy at an angle  180 -X relative to the skin tissue, whereby energy distributions from the two ultrasound transducers are superimposed to provide homogenous energy distribution. 
     
     
         20 . The apparatus of  claim 18 , wherein the controller is configured to drive the one or more drivers one of sequentially or simultaneously. 
     
     
         21 . The apparatus of  claim 18 , wherein the two transducers are activated by the programmable controller to operate at one of the same or different frequencies. 
     
     
         22 . The apparatus of  claim 18 , wherein the activation of the two transducers causes one or more of skin tightening and fat heating. 
     
     
         23 . The apparatus of  claim 18 , further comprising a polygonal-shaped hollow housing and wherein the two transducers are mounted within the housing and arranged to face each other. 
     
     
         24 . The apparatus of  claim 23 , further comprising a device for causing suction within the cavity, the suction, when activated by the programmable controller, causing the skin tissue surface to contact the two transducers. 
     
     
         25 . A method for treating skin tissue comprising:
 providing two ultrasound transducers for placement on the skin tissue surface;   providing one or more drivers for driving the two transducers;   a controller configured to control the one or more drivers;   mounting the two transducers angled with respect to the tissue surface towards one another;   delivering ultrasonic energy to the skin tissue through the two transducers, wherein the two transducers are angled with regard to the tissue surface towards one another such that, when activated by the programmable controller, the ultrasound being delivered to the skin tissue is superimposed.   
     
     
         26 . The method of  claim 25 , further comprising the steps of one of the two transducers delivering ultrasonic energy at an angle X relative to the skin tissue and the other of the two transducers delivering ultrasound energy at an angle  180 -X relative to the skin tissue, whereby energy distributions from the two ultrasound transducers are superimposed to provide homoegenous energy distribution. 
     
     
         27 . The method of  claim 25 , further comprising driving the one or more drivers one of sequentially or simultaneously.
