Abstract
Abstract An apparatus and method of implanting hair or hair-like strands in areas of the skin of animate beings, comprising a unique fabricated anchorage piece and a novel process for placing the same in the skin, utilizing a hypodermic needle having a grooved barrel and tip portion. The process or method comprises piercing the skin with the assemblage of needle and anchorage member carried thereby, and then advancing the member by means of a suitable plunger in the needle, such that the member is thrust below the surface of the skin while the needle tip is still inserted. The needle is then withdrawn, whereas the anchorage member remains embedded. Strands of hair or hair-like material tied or otherwise secured to the anchorage member emanate from the puncture in the skin created by the needle, thereby providing an especially natural and pleasing appearance not obtainable with most prior methods and procedures of hair replacement.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
199 words
The method of attaching an anchorage member for hair-like strands to an area of the skin, which comprises the steps of placing essentially the entire elongate base portion of an anchorage member in the bore of a hypodermic needle having a slot, and simultaneously placing a tie portion of said anchorage member in said slot whereby a major part of said tie portion lies substantially outside of the theoretical confines of the cylindrical outer surface of the needle and extends in directions generally transverse to the needle axis, piercing the skin with said needle, advancing the base portion of the anchorage member forwardly along said bore and simultaneously advancing said tie portion along the slot of the needle and into the skin so as to be embedded therein, the engagement with the skin of the said tie portion of the anchorage member causing a deformation of the same with respect to the base portion of the anchorage member so as to enable both portions to pass through the hole made by the needle with minimal enlargement of said hole, and thereafter removing the needle while allowing the base portion of the anchorage member to remain embedded in the skin.
Claim 2
Independent Claim
199 words
The method of attaching an anchorage member for hair-like strands to an area of the skin, which comprises the steps of placing essentially the entire elongate base portion of an anchorage member in the bore of a hypodermic needle having a slot, and simultaneously placing a tie portion of said anchorage member in said slot whereby a major part of said tie portion lies substantially outside of the theoretical confines of the cylindrical outer surface of the needle and extends in directions generally transverse to the needle axis, piercing the skin with said needle, advancing the base portion of the anchorage member forwardly along said bore and simultaneously advancing said tie portion along the slot of the needle and into the skin so as to be embedded therein, the engagement with the skin of the said tie portion of the anchorage member causing a deformation of the same with respect to the base portion of the anchorage member so as to enable both portions to pass through the hole made by the needle with minimal enlargement of said hole, and thereafter removing the needle while allowing the base portion of the anchorage member to remain embedded in the skin.
Claim 3
Dependent Claim
23 words
The method as set forth in claim 1, and further including the step of attaching a strand of hair to the anchorage member.
Claim 4
Dependent Claim
37 words
The method as set forth in claim 2, wherein part of the tie portion of the anchorage member protrudes from the scalp, said method including the further step of attaching additional hair-like strands to said tie portion.
Claim 5
Dependent Claim
37 words
The method as set forth in claim 1, wherein the tie portion of the anchorage member comprises a loop which portrudes from the scalp, said method including the step of fastening a hair-like strand on said loop.
Claim 6
Dependent Claim
38 words
The method as set forth in claim 1, wherein the tie portion of the anchorage member comprises a loop, and wherein the step of advancing the anchorage member comprises embedding the loop below the surface of the scalp.
Claim 7
Dependent Claim
19 words
The method of claim 5, and further including the step of attaching a strand of hair to the loop.
Claim 8
Dependent Claim
26 words
The method of claim 6, wherein the step of piercing the skin creates a passageway from which the strand emanates, following removal of the hypodermic needle.
Claim 9
Dependent Claim
45 words
The method as set forth in claim 1, wherein the anchorage member tie portion comprises a loop and wherein the step of advancing said portions of the anchorage member comprises bending the loop toward the base portion as the member is embedded into the skin.
