Method and apparatus for transplanting a hair graft
First Claim
1. An apparatus for transplanting a hair graft, comprising:
- a housing including an actuator chamber and a hair graft chamber with an open distal end, the hair graft chamber for housing a loaded hair graft;
a gas-permeable rod inside the housing, an end of the rod being movable to a position along a central axis of the housing;
a vacuum source operably coupled to the housing to provide suction through the gas-permeable rod and at the open distal end for drawing a hair graft into the hair graft chamber; and
an actuator to move the end of the rod substantially flush with the open distal end so that the loaded hair graft is delivered to a scalp wound,wherein the end of the rod is movable between a first position and a second position, wherein, with the end of the rod in the first position, the housing provides a spacing between the end of the rod and the open distal end of the housing to receive a hair graft, and wherein, with the end of the rod in the second position, the end of the rod is substantially flush with the open distal end of the housing, so that the hair graft is delivered to a scalp wound.

Abstract
A hair transplant apparatus and method capture a hair graft into a hair graft chamber readily aligned for implantation into the human scalp. The hair graft can be placed into the hair graft chamber manually or mechanically (e.g., by vacuum). A hair transplant apparatus includes a gas-permeable stopper for utilizing gas flow to load and/or implant a hair graft. Another hair transplant apparatus includes a gas-permeable rod inside a housing. Vacuum may be utilized to load a hair graft into the hair graft chamber. The rod may be advanced toward an open distal end of the chamber so the end of the rod becomes substantially flush with the distal end, thereby pushing the hair graft out of the chamber and into the pre-made wound. Advantageously, the chamber is aligned with the direction of the pre-made wound allowing the hair graft to slide easily into the pre-made wound without damage. Extraneous forces are eliminated by the alignment of the chamber to the wound, thus creating a linear path for the hair graft to move without obstruction to finally settle in the scalp wound.
