Abstract
An improved method of selectively annealing a needle and the needle prepared by the improved method is disclosed. A curved needle is positioned adjacent a flat electromagnetic induction coil. The curved body of the needle is positioned in a plane parallel with the coil plane of the flat induction coil. A current is delivered through the coil to selectively heat and consequently selectively anneal a portion of the needle. The improved method enables the selective annealing of curved needles, and is especially useful for the manufacture of surgical needles.
