Abstract

Abstract An appliance and method for correcting ingrown toenails. A thin, flat resilient strip is conformed to the shape of the toenail and adhesively attached to the toenail with a suitable adhesive. The strip extends to within one-eighth inch of either opposite side of the toenail, and when so applied, tends to bend resiliently bend back to its original flat shape. The corresponding torque effect created on the toenail is sufficient to cause the affected ingrown toenail to grow out into a naturally correct position. The strip may be of a heat-sensitive material which is more pliable when heat is applied, and which resumes a greater degree of rigidity when the heat is dissipated. Bevelling of the edges around the outer perimeter of the strip smooths the transition of the strip into the surface of the toenail for aesthetic purposes.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 136 words
A method for correcting an ingrown toenail of a user, the toenail having two opposite sides and an upper surface exposed to the air, comprising the steps of: providing a thin, flat resilient strip; adhesively attaching said strip to the upper surface of the toenail, said strip being cut by the user prior to application so that said strip extends to within a substantially uniform distance of one-eighth inch from either of the opposite sides of the toenail but not extending to the opposite sides of the toenail, said strip when so applied to the toenail being bent to the curvature of the toenail surface of develop an upward torque on the sides of the toenail; and said torque urging said sides upward sufficiently to cause the nail to grow out into a naturally correct position.
Claim 2
Independent Claim 136 words
A method for correcting an ingrown toenail of a user, the toenail having two opposite sides and an upper surface exposed to the air, comprising the steps of: providing a thin, flat resilient strip; adhesively attaching said strip to the upper surface of the toenail, said strip being cut by the user prior to application so that said strip extends to within a substantially uniform distance of one-eighth inch from either of the opposite sides of the toenail but not extending to the opposite sides of the toenail, said strip when so applied to the toenail being bent to the curvature of the toenail surface of develop an upward torque on the sides of the toenail; and said torque urging said sides upward sufficiently to cause the nail to grow out into a naturally correct position.
Claim 3
Dependent Claim 110 words
A method for correcting an ingrown toenail as claimed in claim 1, wherein: said strip is heat-sensitive, such that when heat is applied prior to the attachment to the toenail the strip becomes temporarily more pliable, and subsequently resumes a greater degree of rigidity after said applied heat has dissipated; said strip is cut to size by the user so that when attached to the toenail surface said strip covers at least thirty percent of the surface area thereof; and the outer perimeter of said strip is bevelled so that the strip merges with the toenail in such a way as to give the cosmetic appearance of one continuous surface.
