Definitions

  • the present invention relates to a device for applying high-frequency vibrations to objects, which device is particularly useful for removing hair.
  • a hair is composed of a protein named keratin arranged in three layers, termed the outer cuticle, the middle cortex and the central medulla. Hair grows from a follicle, which is a small cup-shaped pit buried under the skin. The walls of the follicle form the outer root sheath of the hair. The base of the hair follicle called the dermal papilla, is fed by the bloodstream which carries nourishment (e.g., nutrients and oxygen) to produce new hair and removes waste materials formed in the process (e.g., CO 2 ). The lower part of the follicle widens out to form a hair bulb containing a germinal matrix, which is the source of hair growth.
  • nourishment e.g., nutrients and oxygen
  • Hair growth is initiated in the hair bulge, which is a small swell of the hair follicle that forms the attachment site of a small smooth muscle, called the arrector pili muscle.
  • the dermal papilla sends signals to the stem cells in the hair bulge to migrate downwards along the follicle.
  • the stem cells begin to proliferate and, following cell differentiation, a new hair shaft is formed.
  • Various methods and devices exist for removal of undesired hair generally pluck hair affixed to a tissue using various types of gripping, pulling and/or cutting means.
  • the existing techniques can be classified into two major categories: short-term and long-term hair removal techniques.
  • short-term hair removal techniques the hair is removed without significantly damaging the biological regeneration and/or re-growth mechanisms found at the base of each hair.
  • Such technique affects only that part of the hair shaft which is located outside the skin, while the living part of the hair (the hair follicle attached to dermal papilla) continues to grow.
  • the most common short-term hair removals techniques include: shaving, rotary mechanical epilation, waxing and chemical depilation.
  • Long-term hair removal techniques affect the biological re-growth mechanisms of the removed hair, and thus have the potential of inhibiting re-growth of unwanted hair from the treated organ.
  • the most common long-term hair removal techniques include: electrolysis, laser and intense pulsed (non-laser) light.
  • a companion application Ser. No. 10/590,477 filed Feb. 20, 2005, and assigned to the same assignee discloses methods and devices for removing hair based on the transmission of acoustic waves through the hair shaft to generate sufficient heat to destroy the hair root.
