Abstract

A skin rejuvenation resurfacing apparatus comprising an oscillating, reciprocating high speed, needle-based device and its related procedure for inducing mechanical trauma to an area of the skin to be treated.

Claims (25)

1. An apparatus for use in a skin resurfacing and collagen remodeling procedure through creating of a mechanical trauma transdermally, the apparatus comprising:

a needle array comprising a plurality of needles;

a needle tip protector attached over the plurality of needles;

a reciprocating mechanism connected to the needle array and providing cyclic in and out movement of the plurality of needles between a completely retracted position within the needle tip protector to a completely extended position corresponding to a maximum skin penetration depth, with oscillating frequency at a predetermined cycles per second; and

an RF source connected to the needle array such that RF energy from the RF source is deliverable transdermally through the plurality of needles during the cyclic skin penetration;

wherein a RF power and the oscillating frequency of the plurality of needles are set to create tissue and blood coagulation around each of the plurality of needles during skin penetration.

2. The apparatus according to claim 1 , wherein the maximum skin penetration depth of the plurality of needles is adjustable from about 0.5 mm to about 500 mm.

3. The apparatus according to claim 1 , wherein said oscillating frequency of said plurality of needles is about from 1Hz to 500Hz.

4. The apparatus according to claim 1 , wherein a diameter of each of said plurality of needles is in a range of about 50 microns to 500 microns.

5. The apparatus according to claim 1 , further comprising a scanning system that automatically moves said needle array with a predetermined speed.

6. The apparatus according to claim 1 , wherein the needle array comprises a needle sheath generally covering an elongate needle portion of said needle array and ending near the plurality of needles, said needle sheath further serving as means for preventing a side to side movement of the elongate needle portion; and

wherein the needle tip protector is attached over the plurality of needles, said needle tip protector being slidably operable over the plurality of needles for setting a desired depth of needle penetration into a skin area being treated.

7. An apparatus for use in a skin resurfacing and collagen remodeling procedure through creating of a mechanical trauma transdermally, the apparatus comprising:

a needle array comprising a plurality of needles;

a needle tip protector attached over the plurality of needles;

a reciprocating mechanism connected to the needle array and providing cyclic in and out movement of the plurality of needles between a completely retracted position within the needle tip protector to a completely extended position corresponding to a maximum skin penetration depth, with oscillating frequency at a predetermined cycles per second;

a heating unit by which heat is imparted to the plurality of needles during the cyclic movement thereof and deliverable transdermally through the plurality of needles during the cyclic skin penetration; and

a hand piece holding the reciprocating mechanism and the heating unit;

wherein a heating temperature of the heating unit and the oscillating frequency of the plurality needles are set to create tissue and blood coagulation around each of the plurality of needles during skin penetration.

8. The apparatus according to claim 7 , wherein the maximum skin penetration depth of the plurality of needles is adjustable from about 0.5 mm to about 500 mm.

9. The apparatus according to claim 7 , wherein said oscillating frequency of said plurality of needles is about from 1Hz to 500Hz.

10. The apparatus according to claim 7 , wherein a diameter of each of said plurality of needles is in a range of about 50 microns to 500 microns.

11. The apparatus according to claim 7 , further comprising a scanning system that automatically moves said needle array with a predetermined speed.

12. The apparatus according to claim 7 , wherein the needle array comprises a needle sheath generally covering an elongate needle portion of said needle array and ending near the plurality of needles, said needle sheath further serving as means for preventing a side to side movement of the elongate needle portion; and

wherein the needle tip protector is attached over the plurality of needles, said needle tip protector being slidably operable over the plurality of needles for setting a desired depth of needle penetration into a skin area being treated.
