Abstract

Methods for dissecting tissues are provided. The methods comprise selecting a tissue site comprising dermis and subdermal fat connected to the dermis, and applying ultrasonic energy to the tissue to remove at least a portion of the subdermal fat from the dermis, wherein the ultrasonic energy is applied to minimize damage to the dermis.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for dissecting tissues, comprising:
 selecting tissue from a cadaver or animal source, the tissue comprising dermis and subdermal fat connected to the dermis;   applying ultrasonic energy to the tissue to remove at least a portion of the subdermal fat from the dermis, wherein the ultrasonic energy is applied to minimize damage to the dermis; and   cooling the dermis while applying the ultrasonic energy by contacting the dermis with a cooling jacket.   
     
     
         2 . The method of  claim 1 , wherein at least a portion of the dermis is not heated to greater than 50° C. during application of the ultrasonic energy. 
     
     
         3 . The method of  claim 2 , wherein the entire dermis is not heated to greater than 50° C. during application of the ultrasonic energy. 
     
     
         4 . The method of  claim 1 , wherein the ultrasonic energy is applied at a frequency of at least 20 kHz. 
     
     
         5 . The method of  claim 1 , wherein the ultrasonic energy is pulsed. 
     
     
         6 . The method of  claim 1 , wherein the ultrasonic energy is applied at a junction between the dermis and subdermal fat. 
     
     
         7 . The method of  claim 1 , wherein the ultrasonic energy is applied to cut, melt, or emulsify fat. 
     
     
         8 . The method of  claim 1 , wherein substantially all the subdermal fat is removed from the dermis. 
     
     
         9 . The method of  claim 1 , wherein the subdermal fat is attached to a cadaver, and the ultrasonic energy is applied to separate the dermis from the cadaver. 
     
     
         10 . The method of  claim 1 , wherein the subdermal fat and dermis are in the form of a sheet of tissue. 
     
     
         11 . A method for dissecting tissues, comprising:
 selecting tissue from a cadaver or animal source, the tissue comprising dermis and subdermal fat connected to the dermis;   cooling the dermis, wherein the cooling is performed by contacting the dermis with a cooling jacket; and   applying ultrasonic energy to the tissue to separate at least a portion of the subdermal fat from the dermis.   
     
     
         12 . The method of  claim 1 , wherein at least a portion of the dermis is not heated to greater than 50° C. during application of the ultrasonic energy. 
     
     
         13 . The method of  claim 2 , wherein the entire dermis is not heated to greater than 50° C. during application of the ultrasonic energy. 
     
     
         14 . The method of  claim 1 , wherein the ultrasonic energy is applied at a frequency of at least 20 kHz. 
     
     
         15 . The method of  claim 1 , wherein the ultrasonic energy is pulsed. 
     
     
         16 . The method of  claim 1 , wherein the ultrasonic energy is applied at a junction between the dermis and subdermal fat. 
     
     
         17 . The method of  claim 1 , wherein the ultrasonic energy is applied to cut, melt, or emulsify fat. 
     
     
         18 . The method of  claim 1 , wherein substantially all the subdermal fat is removed from the dermis. 
     
     
         19 . The method of  claim 1 , wherein the subdermal fat is attached to a cadaver, and the ultrasonic energy is applied to separate the dermis from the cadaver. 
     
     
         20 . The method of  claim 1 , wherein the subdermal fat and dermis are in the form of a sheet. 
     
     
         21 . The method of  claim 1 , wherein cooling the dermis comprises freezing the dermis.
