Abstract
Abstract A method of treating a toenail or fingernail for correcting an ingrown condition which comprises applying a material in flowing or liquid form across the nail at the base or proximal portion in a limited area having a normal radius of curvature, causing the material to harden and to become adhered to the nail and to serve as a form-retaining support, permitting the support to remain adhered to the nail as the nail grows over a period of time until the coated and supported portion extends beyond the end of the toe, and removing the portion of the nail having the coated material thereon, the nail remaining being partially or totally cured of the ingrown condition.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
153 words
A method for treating an ingrown nail condition which comprises applying a coating consisting essentially of a hardenable substantially liquid material having adhesive properties with respect to the surface of the nail over a rearwardly disposed limited area substantially across the entire width of the nail and at an area having a substantially normal radius of curvature, permitting said material to harden and to become affixed to the surface of the nail to form a support, and permitting the hardened material to remain on said nail until it has progressed forwardly to a position at the forward end of said nail and has substantially increased the radius of curvature at the forward end of the nail, and removing said hardened material, the thickness of said coating being sufficient to retain substantially the curvature of the coated portion of said nail as it grows to the end of the toe and is eventually removed.
Claim 2
Independent Claim
153 words
A method for treating an ingrown nail condition which comprises applying a coating consisting essentially of a hardenable substantially liquid material having adhesive properties with respect to the surface of the nail over a rearwardly disposed limited area substantially across the entire width of the nail and at an area having a substantially normal radius of curvature, permitting said material to harden and to become affixed to the surface of the nail to form a support, and permitting the hardened material to remain on said nail until it has progressed forwardly to a position at the forward end of said nail and has substantially increased the radius of curvature at the forward end of the nail, and removing said hardened material, the thickness of said coating being sufficient to retain substantially the curvature of the coated portion of said nail as it grows to the end of the toe and is eventually removed.
Claim 3
Dependent Claim
19 words
A method according to claim 1, wherein said substantially liquid material is a plastic liquid hardenable at room temperature.
Claim 4
Dependent Claim
22 words
A method according to claim 2, wherein said plastic liquid comprises a mixture of polymeric and monomeric methylmethacrylate and a catalyst therefor.
Claim 5
Dependent Claim
22 words
A method according to claim 2, wherein said plastic liquid is an epoxy resin containing a catalyst and hardenable at room temperature.
Claim 6
Dependent Claim
29 words
A method according to claim 1, wherein said material is applied at the base of the nail in a strip extending substantially across the entire width of the nail.
Claim 7
Dependent Claim
21 words
A method according to claim 5, wherein said strip is about 1/16 inch thick and about 1/8 to 3/16 inch wide.
Claim 8
Dependent Claim
12 words
A method according to claim 1, wherein said nail is a toenail.
Claim 9
Dependent Claim
21 words
A method according to claim 1, wherein said hardened material is subsequently removed from said nail by means of a solvent.
Claim 10
Dependent Claim
20 words
A method according to claim 1, wherein said hardened material is subsequently removed from said nail by application of heat.
Claim 11
Dependent Claim
44 words
A method according to claim 7, wherein said hardened material is subsequently removed from said nail by cutting off the coated portion of said nail when said coating is on a free portion thereof extending beyond the end of the toe supporting said nail.
