Abstract
A cosmetic procedure for hair transplantation is carried out with an apparatus (50) comprising a magazine (52) with a plurality of compartments (53) each containing a sample of de-epithelialized tissue having at least one hair shaft attached to a hair bulb. The magazine (52) is loaded in an apparatus (50) having a tapered hollow lumen (57) aligned with a pusher rod (56). With the hollow lumen (57) penetrating a recipient graft site to a predetermined depth and the pusher rod (56), the hollow lumen (57) and a compartment (53) in axial alignment, pusher rod (56) moves through compartment (53) and into the hollow lumen (57) to deposit a portion of donor tissue in the recipient graft site.
