Cosmetic skin rejuvination

Abstract

A device for cosmetic treatment of human skin, including: a needle for inserting into the skin; a DC power source electrically connected to the needle for providing negative current to the needle; an anode that is electrically connected to the DC power source to receive positive current, and that is adapted to be placed in contact with the skin of the person into which the needle is inserted to form a closed electrical circuit; at least one RF transmitter coupled to the needle for radiating the area around where the needle is inserted to provide heat while the needle is deployed.

1 - 15 . (canceled) 
     
     
         16 . A cosmetic method for treating a patient's skin, comprising:
 providing an array of needles, deploying the array of needles to a specific depth into the patient's skin such that at least a tip of one of the array of needles is deployed within the muscle layer of the patient's skin;   providing a DC power source and one or more radio frequency (RF) transmitters coupled to the array of deployed needles;   applying a negative DC voltage to said array of deployed needles from the DC power source, while the patient is in contact with a positive electrode to form a closed circuit of DC current through the patient's body;   providing the DC current for a pre-selected amount of time to treat muscles and/or muscle nerve cells in the muscle region of the patient's skin;   transmitting RF radiation from the one or more RF transmitters for a pre-selected period of time to heat up the deployed needles and patient's skin; and   wherein the RF radiation is transmitted separately from the application of DC voltage and only when the DC voltage is turned off and vice versa.   
     
     
         17 . The method according to  claim 16 , further comprising providing hollow conduits in said array of deployed needles and the step of supplying liquids into the skin through the hollow conduits formed in said needles. 
     
     
         18 . The method according to  claim 16 , further comprising measuring electrical resistance of the closed circuit to determine the depth of the array of deployed needles in the patient's skin. 
     
     
         19 . The method according to  claim 18 , further comprising providing an indication of said depth. 
     
     
         20 . The method according to  claim 16 , wherein said array of deployed needles are deployed so as to locate their tips below the subcutaneous layer. 
     
     
         21 . The method according to  claim 18 , wherein the electrical resistance is measured before and after treatment to determine the level of success of the treatment. 
     
     
         22 . The method of  claim 17 , further comprising a syringe for supplying the liquids. 
     
     
         23 . The method of  claim 22 , further comprising a motor to control the supply of the liquids from the syringe into the skin. 
     
     
         24 . The method of  claim 16 , wherein said array of deployed needles are partially insulated and the tips of the array of needles are not insulated. 
     
     
         25 . The method of  claim 16 , further comprising the step of providing one of the same or different current to each needle of the array of deployed needles. 
     
     
         26 . The method of  claim 16 , wherein the array of deployed needles each serve as a cathode and wherein the positive electrode serves as an anode. 
     
     
         27 . An apparatus for cosmetically treating a patient's skin, comprising:
 an array of needles,   the array of needles being configured to be deployed to a specific depth into the patient's skin such that at least a tip of one of the array of needles is deployed within the muscle layer of the patient's skin;   a DC power source and one or more radio frequency (RF) transmitters coupled to the array of deployed needles;   wherein a negative DC voltage is configured to be applied to said array of deployed needles from the DC power source while the patient is in contact with a positive electrode that forms a closed circuit of DC current through the patient's body;   wherein the DC current is configured to be applied for a pre-selected amount of time to treat muscles and/or muscle nerve cells in the muscle region of the patient's skin;   wherein RF radiation from the one or more RF transmitters is configured to be transmitted for a pre-selected period of time to heat up the deployed needles and patient's skin; and   wherein the RF radiation is configured to be transmitted separately from the application of DC voltage and only when the DC voltage is turned off and vice versa.
