Abstract
Abstract A method of replacing hair to a delineated area of a body. After surgically preparing the area, a series of continuous sutures are embedded therein by a surgeon in a concentric ring pattern. Each suture is of inert material and is embedded so as to form a pattern of loops alternately projecting above and below the surface of the delineated area. Subsequently, wefts of human or synthetic hair are sewn to one or more of the loops until the area is covered with hair.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
84 words
A method of replacing hair in a delineated area of a living human body which has been surgically prepared comprising the steps of: embedding a series of sutures in a concentric ring pattern in the delineated area by inserting the sutures into the body below the surface of the delineated area and looping the sutures above the surface of the delineated area; and directly attaching wefts of replacement hair to the loops formed by the sutures thereby substantially covering the delineated area with hair.
Claim 2
Independent Claim
84 words
A method of replacing hair in a delineated area of a living human body which has been surgically prepared comprising the steps of: embedding a series of sutures in a concentric ring pattern in the delineated area by inserting the sutures into the body below the surface of the delineated area and looping the sutures above the surface of the delineated area; and directly attaching wefts of replacement hair to the loops formed by the sutures thereby substantially covering the delineated area with hair.
Claim 3
Dependent Claim
45 words
A method of replacing hair as defined in claim 1 which, after the smallest diameter concentric ring has been embedded in the delineated area, includes the step of embedding at least one continuous suture in a straight line substantially diametrically across the smallest diameter ring.
Claim 4
Independent Claim
176 words
A method of replacing hair in a delineated area of a living human scalp which has been surgically prepared comprising the steps of: embedding a series of sutures in a concentric ring pattern in the delineated area by inserting each suture so that the suture enters the layer of skin covering the scalp, extends downward into the subcutaneous tissue and then loops back up and out through the layer of skin thereby forming a pattern of loops alternately projecting above and below the scalp; continuing the embedding procedure until each ring has been completed with free ends of the suture exposed; securing the free ends together to form a final outwardly projecting loop and make the suture continuous, the concentric ring at the periphery of the delineated area having a larger diameter than the remaining inner rings and each successive ring extending inwardly from the outer ring having a correspondingly smaller diameter; and directly attaching wefts of replacement hair to the outwardly projecting loops formed by the sutures thereby substantially covering the delineated area with hair.
