ABSTRACT:
In one aspect, the invention provides a method for transplanting hair. According to the method, an instrument is provided having a concentric cylindrical shaft having a proximal end, a distal end, and an axis extending therebetween A blade is on the distal end of the shaft normal to the axis of the shaft, and an escape port is provided in the wall of the shaft near the distal end. The instrument is inserted into the skin to a preselected depth where the skin is below the escape port to form a cylindrical incision. The instrument is then removed from the skin. The step of inserting the instrument into the skin is repeated, with any accumulated skin in the shaft being forced through the escape port. In this way, the shaft does not become clogged with tissue after repeated use. A graft of skin having at least one hair is then placed into at least one of the cylindrical incisions.
