Claims

1. An apparatus comprising:

a plurality of needles attached to a base; and

an energy source arrangement in communication with one or more of the needles, wherein the optical energy source arrangement is configured to (i) provide optical energy to at least one portion of tissue, and (ii) direct the optical energy to cause at least one a thermal damage or an ablation of at least one of a dermal layer or a subdermal layer of the at least one portion of the tissue.


  2. The apparatus of claim 1 wherein two or more of the needles are electrically conductive and the energy source is configured to supply the optical radiation individually to one or more of the needles.
  3. The apparatus of claim 2, further comprising a control module which is configured to facilitate a variation of the characteristics of the optical energy supplied by the energy source, wherein the energy source and/or control module is located outside of a housing to which the base is attached.
  4. The apparatus of any one of claims 1 to 3 wherein the energy source is a laser device.
  5. The apparatus of claims 3 wherein the control module provides application-specific settings to the energy source, and wherein the energy source receives the settings, and generates the energy directed to and optionally from specified needles for selectable or predetermined durations, intensities, and sequences based on the settings.
  6. The apparatus of anyone of claims 1 to 5 wherein the needles comprise sharp distal ends capable of piercing the surface of skin tissue and penetrating into the tissue until the lower side of the base contacts the surface of the skin.
  7. The apparatus of anyone of claims 3 and/or 6 wherein the control module is configured to deliver controlled amounts of the energy to one or more of the needles.
  8. The apparatus of anyone of claims 1 to 78 further comprising a housing, wherein the base is attached to at least a portion of the housing.
  9. The apparatus of claim 1 wherein at least two of the needles have different lengths.
  10. The apparatus of any one of claims 1 to 9 wherein the subdermal layer includes a fat section, and wherein the optical energy causes at least one the thermal damage or the ablation to the fat section.
  11. A method of-cosmetic treatment comprising:

providing a plurality of needles attached to a base;

providing an optical energy source in communication with two or more of the needles;

controlling a penetration depth of the needles using a spacer substrate through which the needles protrude, wherein a position of the substrate is adjustable relative to a position of the base to control a length of the needles protruding from a lower surface of the spacer substrate;

inserting the needles into the skin to a predetermined depth; and

supplying energy to more than one of the needles to induce a pattern of damage in the tissue surrounding the needles, thereby causing at least one of a thermal damage or an ablation of at least one of a dermal layer or a subdermal layer of at least one portion of the tissue.


  12. The method of claim 11 wherein at least two of the needles have different lengths.
  13. The apparatus of any one of claims 11 and/or 12 wherein the subdermal layer includes a fat section, and wherein the optical energy causes at least one the thermal damage or the ablation to the fat section
