Abstract
Abstract A method is disclosed for implanting hair into human skin comprising the steps of inserting an end of a hollow outer needle into skin to form a pit in the surface thereof, sliding an inner needle within the outer needle to position an end of the inner needle supporting a bulbous end of a hair within the skin pit adjacent the end of the outer needle, and extracting the outer and inner needles from the skin pit. Apparatus is also disclosed for implanting hair into human skin which apparatus comprises a hollow outer needle having a relatively sharp end for piercing skin, a hollow inner needle slidably disposed within the hollow outer needle and having a centrally apertured relatively blunt end for receiving a hair therethrough and for supporting a bulbous hair end on the surface thereof, and means for moving the inner needle blunt end between positions remote and positions closely adjacent the outer needle sharp end. Hair implantation apparatus is further described comprising a needle having a slot formed in an injection end thereof from which a passageway extends. A hairlike filament is loosely positioned within the needle passageway with an anchor at one end thereof in the shape of an arrowhead slidably positioned within the needle slot.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
143 words
A method of implanting hair in human skin comprising the steps of: a. tightly tieing two end loop members and loosely tieing at least one intermediate open loop member in a series of loops on the end of a hair thereby forming a bulb having at least one passageway therethrough on the end of a hair to be implanted; b. placing the hair in a 1st hollow needle with the bulb positioned adjacent an end thereof; c. placing the 1st hollow needle within a 2nd hollow needle with the hair bulb disposed within the 2nd hollow needle; d. piercing the skin with the 2nd hollow needle; e. sliding the 1st hollow needle within the 2nd hollow needle to position the hair bulb adjacent the end of the 2nd hollow needle; and f. sliding the 1st and 2nd hollow needles out of the skin.
Claim 2
Independent Claim
143 words
A method of implanting hair in human skin comprising the steps of: a. tightly tieing two end loop members and loosely tieing at least one intermediate open loop member in a series of loops on the end of a hair thereby forming a bulb having at least one passageway therethrough on the end of a hair to be implanted; b. placing the hair in a 1st hollow needle with the bulb positioned adjacent an end thereof; c. placing the 1st hollow needle within a 2nd hollow needle with the hair bulb disposed within the 2nd hollow needle; d. piercing the skin with the 2nd hollow needle; e. sliding the 1st hollow needle within the 2nd hollow needle to position the hair bulb adjacent the end of the 2nd hollow needle; and f. sliding the 1st and 2nd hollow needles out of the skin.
Claim 3
Dependent Claim
27 words
The hair implantation method of claim 1 Comprising the step (f) sliding the 1st and 2nd hollow needles over the hair out from the human skin simultaneously.
Claim 4
Dependent Claim
39 words
The hair implantation method of claim 1 Comprising the step (f) sliding the 2nd hollow needle over the hair out from the human skin and subsequently sliding the 1st hollow needle over the hair out from the human skin.
Claim 5
Dependent Claim
118 words
Apparatus for implanting hair in human skin comprising in combination, a 1st handle defining a slot, a hollow outer needle secured to said 1st handle and having a relatively sharp end for piercing skin; a 2nd handle of substantially H-shaped configuration mounted in mutual sliding engagement in said 1st handle slot; a hollow inner needle secured to said 2nd handle and slidably disposed within said hollow outer needle and having a centrally apertured relatively blunt end for receiving a hair therethrough and for supporting a bulbous hair end on the surface thereof, and means for moving said inner needle blunt end between positions extending beyond said hollow needle sharp end and positions within said outer needle sharp end.
Claim 6
Dependent Claim
118 words
Apparatus for implanting hair in human skin comprising in combination, a 1st handle defining a slot, a hollow outer needle secured to said 1st handle and having a relatively sharp end for piercing skin; a 2nd handle of substantially H-shaped configuration mounted in mutual sliding engagement in said 1st handle slot; a hollow inner needle secured to said 2nd handle and slidably disposed within said hollow outer needle and having a centrally apertured relatively blunt end for receiving a hair therethrough and for supporting a bulbous hair end on the surface thereof, and means for moving said inner needle blunt end between positions extending beyond said hollow needle sharp end and positions within said outer needle sharp end.
Claim 7
Dependent Claim
26 words
Hair implantation apparatus in accordance with claim 4 comprising indexing means for indicating relative axial positions of said inner needle with respect to said outer needle.
Claim 8
Dependent Claim
86 words
In the method of implanting a human hair into skin by which a hollow needle is inserted into skin to form a pit in the surface thereof and a bulbous end of a hair supported within the hollow needle is positioned within the skin pit, the improvement comprising forming the bulbous end on the human hair end prior to implantation by tying the human hair end into a loop with a spacial interstice through which skin tissue may subsequently grow and thereby tenaciously anchor the hair.
Claim 9
Dependent Claim
86 words
