ABSTRACT:
A method and apparatus for forming multiple cavities in the tissue of a patient into which hair transplant grafts are placed is disclosed. The apparatus comprises interengaging plates. A first plate includes a number of downwardly extending spikes for extension through a number of downwardly extending hollow catheters of a second plate. The first and second plates are pressed together with the interengaging spikes and catheters penetrating the tissue. The first plate is removed, leaving cavities formed by the hollow catheters of the second plate. A third plate having downwardly extending hollow catheters filled with hair grafts is sleeved into or aligned with the catheters of the first plate. The hair grafts are pressed downward through the third plate, through the first plate, into the scalp, preferably by use of rods extending down from a fourth plate. The third plate may take the form of a rotatable circular wheel or replaceable cartridge which has bores therethrough for holding hair grafts, which is located between the first plate and the second plate.
