Claims

1. A method of treating skin comprising the steps of:

providing a plurality of needles attached to a base;

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

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

supplying energy to more than one of the needles.


  2. The method of claim 2 further comprising:

providing a control module, wherein the control module permits variation of the characteristics of energy supplied by the energy source.


  3. The method of claim 1 or 2 further comprising:

providing cooling means to cool the surface of the skin, and optionally the plurality of needles, before inserting the needles into the skin.


  4. The method of one of claims 1 to 3 wherein the energy is RF current and the needles are insulated except near their tips.
  5. The method of one of claims 1 to 4 further comprising:

providing a detection device in communication with one or more of the needles;

supplying low current to one or more of the needles sequentially to detect the presence of a nerve near the needles; and

preventing the energy source from supplying energy to any needle if a nerve has been detected near that needle.


  6. The method of one of claims 1 to 5 further comprising:

providing one or more hollow needles attached to the base and injecting an analgesic through the hollow needles into the surrounding tissue after the needles are inserting into the skin.


  7. The method of one of claims 1 to 6 further comprising:

providing hollow needles containing light fibers or light guides in communication with the energy source, wherein the energy source is a source of optical energy;

supplying energy to the light fibers or light guides to induce thermal damage in a portion of the tissue surrounding the hollow needles.


  8. The method of one of claims 1 to 7, wherein the energy is optical energy.
  9. Method of operating a tissue reshaping apparatus, the tissue reshaping apparatus comprising:

an array of needles;

a plurality of the needles having a tip adapted to contact with the tissue;

the method comprising the step of supplying optical energy to the tips such that the tips are heated.


  10. Tissue reshaping device comprising
an array of needles;
wherein a plurality of the needles has a tip adapted for contact with the tissue; and an energy source for providing energy to the tips for heating the tips.
  11. The tissue reshaping device of claim 10, wherein the energy source provides optical energy to the tips for heating the tips.
