DESCRIPTION:
BRIEF SUMMARY
This invention uses the transmission Ahmad Amiri (Inventor) patent application to Canadian Intellectual Property Office, file No. 2,121,398 filed 15th Apr. 1994 and application to World Intellectual Property Organization, Patent Cooperation Treaty , file No. PCT/CA95/00168 dated 24th Mar. 1995.
FIELD OF INVENTION
This invention is a hair implant and methods of implanting it in the skin with or without lifting the skin, that may be used in treatment of baldness, thin hair or undesirable hair.
DESCRIPTION OF RELATED ART
Current remedies for baldness include: drawbacks are artificial appearance, subject to accidental dislodging, sweat retaining hence less hygienic, and that can't help thin hair. it. Drawbacks are severe limitation, evasiveness, high cost and no use for thin or undesirable hair. area, no guarantee of successful or continued regrowth of donor hair in host skin, high cost, lengthy treatment for several months and sparse looking hair as final result. successful for only some people. Any improvement is reversed once treatment is halted. It is costly and can't help undesirable hair. hair". In this method one or more synthetic hair fibres are knotted together at 10" intervals. Then the bundle is attached to a suturing needle which is inserted into the skin and pulled through the skin and out of the skin such that all knots are out of the skin except for the one furthest from the needle which is let to remain embedded in the skin.
Then the process is repeated leaving the second furthest knot from needle under the skin and so on until all knots are inside the skin serving as anchors keeping the bundle in place. Then the portions of the bundle which are outside the skin are cut midway between each two consecutive knots. The end result is many holes on the skin from each one bundle of several fibres emerging out of skin, each two bundle is anchored by one bulky knot under the skin.
Drawbacks of U.S. Pat. No. 4,103,365 (method of implanting synthetic hair) are: pulling some or all fibres in the bundle will pull the knot out through the same tunnel in the skin which was created at implantation and kept open by the same bundle. between cylindrical adjacent hairs cannot be closed up by the surrounding skin as the outer fibres closest to the perimeter of the hole prevent the skin to close in. out, hence more difficult to heal and being covered, and that in the middle part of each whole there are triangular openings between bundled fibres that render the skin to influx of infection. better anchorage, is pulled through the skin many times. For example a bundle of 10 knots would require 55 passages of knots into, through and out of the skin, extremely damaging to the skin tissue. hair. creates an unsightly `pimple` on the scalp. Thousands of knots necessary to cover a bald head would be uncomfortable, unsightly, and possibly unhealthy. reasons.
Uni-Root Multi-Exit Hair Implant is fundamentally different from U.S. Pat. No. 4, 103,365, as will be explained in the forthcoming disclosure, in particular: knot, but is preferably same thickness as one fibre, entering the skin only once, never exiting the skin, hence causing little damage to tissue and no pimple on the scalp. emerging from its individual exit point, which is different from several fibres sharing passage. open gap. and tunnels in the skin, causing serious damage to tissue. each fibre to exit the skin from its unique point which is different from all fibres attached to same needle. fibres through the skin and reduce skin contact with inserted needles and fibres, resulting in less damage to tissue, which is different from forcing knotted bundles of fibres through the tissue. from the description
SUMMARY OF THE INVENTION
Overcoming the drawbacks of prior art and other advantages are to be achieved by the present invention which provides hair implant in which each fibre is rooted under the skin and comes out separately like natural hair, can have desired thickness, colour, density, curl, length, or direction, may be made of strong material to withs
