Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
154 words
An anchor to be disposed on the portion of a steel needle suture exiting from the human body adjacent a wound on the body for holding the needle in place, the anchor comprising: a body molded from medical grade plastic; the body being formed with first and second cavities each extending into the body from the surface thereof with the axes of the cavities being coaxial, the cavities extending into the body respectively to a depth whereby the cavities are internally separated by a barrier formed by the body; the body being formed with a pair of apertures each extending into the body from the surface thereof with the axes of the apertures being coaxial and being adjacent said barrier and open to said first cavity; and the aperture being for use in receiving a steel suture needle and the first and second cavities being for use in receiving projections on a manipulating tool.
