Abstract
Provided herein is an instrument and method useful to incise in to the skin to a precise depth and at a specific angle with respect to the surface of the skin of a patient, for the extraction of individual follicular groups or individual follicular units. An instrument according to the invention precisely limits the depth of incision, and creates a circular incision around a hair, follicular unit, or follicular cluster in a manner such that no damage occurs to any of the hair shafts.

38. A method for the extraction of a follicular unit from a section of skin, comprising the steps of:
-
(a) penetrating said section of skin to form an incision having a first depth;
(b) inserting a dissection punch into the incision to a second depth that is greater than said first depth and form a follicular unit comprising one or more hair follicles; and
(c) removing the follicular unit from the section of skin. - View Dependent Claims (41, 42, 43, 44, 45, 46, 48, 49, 50, 51, 52)
