Abstract
At least one layer of windings is so arranged to enclose an open space for treatment of a portion of a patient, for example the thorax, or a limb, shaped so that it encloses an open space which is elliptical or oval. The space enclosed thus is an oval or elliptical cylinder and, in a form suitable for treatment of the hip joint, can be an inclined cylinder. The winding is surrounded by a protective layer, for example a polyester resin which additionally can be shaped to provide for a support surface.
