Claim 1
Independent Claim
254 words
In the method of providing hair at the scalp wherein a preformed hairpiece is attached to an anchoring suture in the scalp, the improvement comprising the steps of: a. inserting a needle having an eye at the free end thereof in said scalp at a first point; b. passing said needle under the exterior surface of said scalp and out of said scalp at a reference point spaced from said first point; c. threading a suture filament through said eye at said free end of said needle and withdrawing said needle from said scalp drawing said suture filament into said scalp at said reference point, under the exterior surface of said scalp and out of said scalp at said first point; d. reinserting said needle in said scalp at a second point spaced from said first point; e. passing said needle under the exterior surface of said scalp and out of said scalp at said first point; f. threading a first ring on said suture filament at said first point and then threading said suture filament through said eye at said free end of said needle at said first point; g. again withdrawng said needle from said scalp drawing said suture filament into said scalp at said first point, under the exterior surface of said scalp and out of said scalp at said second point, whereby said first ring is pulled into said scalp at said first point, and h. attaching a hairpiece to said first ring at the exterior surface of said scalp.
Claim 2
Dependent Claim

In the method of providing hair at the scalp wherein a preformed hairpiece is attached to an anchoring suture in the scalp, the improvement comprising the steps of: a. inserting a needle having an eye at the free end thereof in said scalp at a first point; b. passing said needle under the exterior surface of said scalp and out of said scalp at a reference point spaced from said first point; c. threading a suture filament through said eye at said free end of said needle and withdrawing said needle from said scalp drawing said suture filament into said scalp at said reference point, under the exterior surface of said scalp and out of said scalp at said first point; d. reinserting said needle in said scalp at a second point spaced from said first point; e. passing said needle under the exterior surface of said scalp and out of said scalp at said first point; f. threading a first ring on said suture filament at said first point and then threading said suture filament through said eye at said free end of said needle at said first point; g. again withdrawng said needle from said scalp drawing said suture filament into said scalp at said first point, under the exterior surface of said scalp and out of said scalp at said second point, whereby said first ring is pulled into said scalp at said first point, and h. attaching a hairpiece to said first ring at the exterior surface of said scalp.
Claim 3
Dependent Claim
109 words
In the method of providing hair at the scalp as claimed in claim 1 the additional steps of serially reinserting said needle in said scalp at further points each spaced from a preceding point, passing said needle under the exterior surface of said scalp and out of said scalp at said preceding point, threading a further ring on said suture filament and said suture filament through said eye of said needle at each preceding point, and withdrawing said needle from said scalp drawing said suture filament into said scalp at said preceding point, under the exterior surface of said scalp and out of said scalp at said further point.
Claim 4
Dependent Claim
68 words
In the method of providing hair at the scalp as claimed in claim 2 the additional steps of selecting said points of insertion of said needle to form said suture filament into a closed figure with the final point of insertion of said needle being through said reference point and the steps of tensioning and tying said suture filament at said reference point into an endless embedded suture.
Claim 5
Dependent Claim
59 words
In the method of providing hair at the scalp as claimed in claim 3 the additional steps of passing each of a plurality of threads through a different one of said rings and clamping each of said plurality of threads at the exterior surface of said scalp when the associated one of said rings is threaded on said suture.
Claim 6
Dependent Claim
48 words
In the method of providing hair at the scalp as claimed in claim 4 the additional step of unclamping each of said plurality of threads after said suture filament is tied at said reference point and employing said plurality of threads to attach said hairpiece to said rings.
Claim 7
Dependent Claim
38 words
In the method of providing hair at the scalp as claimed in claim 5 the additional step of passing said needle through the epidermis, occipitofrontal muscle and galea of said scalp avoiding the periosteum to the extent possible.
Claim 8
Dependent Claim
40 words
In the method of providing hair at the scalp as claimed in claim 6 the initial step of injecting local anesthetic to anesthetise the entire scalp for a period of time sufficient to perform the remaining steps of said method.
Claim 9
Dependent Claim
61 words
In the method of providing hair at the scalp as claimed in claim 5 the additional step of embedding a second endless suture in said scalp with a second plurality of rings thereon and threads in said rings by repeating the steps claimed in claim 5 with respect to said second suture, second plurality of rings and second plurality of threads.
Claim 10
