Epidermal Marking Pen for use in Surgical Marking and Cosmetics

The current use of surgical marking pens in the operating theater is quite common. However, these pens suffer from many drawbacks. These pens smear and despite the thinness of their tip, the ink spreads so that an initial thin line becomes wide as the skin absorbs the ink. Additionally, if the skin surface is greasy or has any blood or fluid on its surface the above problems are made even worse, but more commonly the pen will not even write. To correct these deficiencies Dr. Chasen has invented a �pinwheel pen� which utilizes a miniaturized pinwheel with each member point being hollow with a sharp end to penetrate the skin just below the epidermis. The ink will flow through each point producing a fine temporary tattoo in which the points will be close enough that the marks appear as a continuous line.

There is a need for effective surgical marking pens and this would be replacing the current standard. There is also a decent market for cosmetic tattoos. This would offer a temporary cosmetic solution without the commitment of a permanent tattoo.
