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.

A hair transplant apparatus and a method for placing hair grafts into pre-made wounds 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 housing and a sliding rod within the housing. When the sliding rod is away from an open distal end of the housing in a first position, a hair graft can be placed into the spacing between an end of the rod and the open distal end of the housing. In a second position, the rod is advanced so the end of the rod becomes substantially flush with the distal end of the housing, thereby pushing the hair graft out of the housing and into the pre-made wound. Advantageously, the housing 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 housing to the wound, thus creating a linear path for the hair graft to move without obstruction to finally settle in the scalp wound.

Apparatus for determining the status of hair bulk in an area of a scalp is operative to provide a metric over a sufficiently large area to permit revisiting with only negligible misalignment error. Accurate re-measurement of hair status in accurately identified areas produces a reliable metric for determining degree of hair loss and or the effectiveness of treatment.

The extraction of a hair graft from a harvesting area of a scalp employs a hollow punch fitted with an auxiliary instrumentation for separating a target graft from collagen fibrils which resist extraction. A water jet which follows the annular path of the punch as it rotates into the scalp is described as well as a vibrating punch alternative embodiment for achieving the desired separation.

The stabilization of the dermal area around a follicular unit of hair for harvesting comprises the introduction of a small volume of fluid into the dermal area around a target follicular unit in order to stabilize the dermal area and initiate a limited time period during which the harvesting of the target follicular unit can occur.

A hair implantation instrument herein employs a simple means for capturing a hair graft in a needle in a position for implantation into a scalp and an escapement mechanism for withdrawing the needle in a manner to leave the graft in the scalp. The needle is moved with respect to a rod which positions an implanted graft properly when the needle is withdrawn. The apparatus also defines a sheath over the needle for properly positioning a graft during a graft capture operation. The escapement mechanism is vacuum controlled in one embodiment and spring controlled in a second embodiment.
