Abstract

A device which is installed onto an ingrown nail of a human toe to correct the ingrown nail, includes a support member affixed to the ingrown nail, and a correcting member supported by the support member and effecting force on the ingrown nail toward the correcting direction for the ingrown portion of the nail. The correcting member may be formed of a superelastic material which is shape-memory-treated to memorize a first shape, and which is deformed to a second shape different from the first shape so as to be installed onto a surface of the ingrown nail of the human toe in the second shape.

Claims

1. A device for correcting an ingrown nail, which is adapted to be installed onto a nail of a human toe to correct the ingrown nail, comprising a superelastic tape consisting essentially of nickel/titanium alloy which is shaped-memory-treated to memorize a first shape, and which is deformed to a second shape different from the first shape so as to be installed onto a surface of the nail of the human toe in said second shape.

2. A device for correcting an ingrown nail, which is adapted to be installed onto a nail of a human toe to correct the ingrown nail, comprising a superelastic wire, consisting essentially of nickel/titanium alloy which is shaped-memory-treated to memorize a first shape, and which is deformed to a second shape different from the first shape so as to be installed onto a surface of the nail of the human toe in said second shape.

3. A device for correcting an ingrown nail, which is adapted to be installed onto a nail of a human toe, comprising:

a support member to be installed onto the nail; and

a correcting member supported by the support member and effecting force on the nail in a correcting direction of the nail;

wherein said support member has a larger area than that of said correcting member, and said correcting member consisting essentially of nickel/titanium alloy which is placed and fixed onto said support member, and which is formed of one of a superelastic tape and a superelastic wire.

4. A device for correcting an ingrown nail, which is adapted to be installed onto a nail of a human toe, comprising:

a support member to be installed onto the nail; and

a correcting member supported by the support member and effecting force on the nail in a correcting direction of the nail;

wherein said support member has a larger area than that of said correcting member, and said correcting member consisting essentially of nickel/titanium alloy which is embedded inside said support member, and which is formed of one of a superelastic tape and a superelastic wire.
