Abstract
The invention contemplates a single-coil configuration adapted for embedment in an orthopedic cast, for use in applying electromagnetic signals for osteogenic therapy. An otherwise flat circular multiple-turn coil is so permanently deformed as to establish a first generally U-shaped projection of the coil in a first viewing aspect which is normal to the coil axis, the deformation being further such as to establish a second generally U-shaped projection of the coil in a second viewing aspect which is normal to the coil axis, said viewing aspects being orthogonally related. The depth of the deformation is common to each of the U-shapes and is approximately one fourth of the combined span of the two U-shapes.
