ABSTRACT:
A method and apparatus for forming multiple cavities in the tissue of a patient into which hair transplant grafts are placed is disclosed. In one form, the apparatus is a cartridge comprising a housing, a guide, and a depressor. The guide comprises a plurality of dilator accepting passages located in the housing or in a template in the housing. The depressor is a plate or actuated plunger located at a first end of the dilators which, when depressed, forces the dilators from the guide into tissue of a patient. In a second form, the apparatus comprises mating male and female templates. The male template includes a number of downwardly extending spikes for engagement with a number of downwardly extending hollow guides on the female template. The spikes of the engaging male and female templates are pressed into the tissue and the male template is removed, leaving cavities formed by the hollow guides of the female template, into which hair grafts are located.
