Methods of harvesting and implanting follicular units using a coaxial tool

A method of transplanting a hair follicular units includes aligning a longitudinal axis of a harvesting cannula of a tool assembly with a longitudinal axis of a selected follicular unit, advancing the harvesting cannula relative to the body surface so that a tissue coring distal end of the harvestin...

Summary:A method of transplanting a hair follicular units includes aligning a longitudinal axis of a harvesting cannula of a tool assembly with a longitudinal axis of a selected follicular unit, advancing the harvesting cannula relative to the body surface so that a tissue coring distal end of the harvesting cannula penetrates the body surface surrounding the selected follicular unit to a depth sufficient to substantially encapsulate the follicular unit, withdrawing the harvesting cannula distal end from the body surface with the follicular unit retained in an interior lumen of the harvesting cannula, advancing an implanting cannula of the tool assembly over the harvesting cannula relative to the body surface so that a tissue piercing distal end of the implanting cannula punctures the body surface and forms an implantation cavity therein, and displacing the follicular unit from the harvesting cannula lumen into the implantation cavity.
