Abstract
Wires are used for conducting ultrasound energy. These wires achieve optimum properties by creating a multiple material coaxial construction. For example, in a particular embodiment it is desirable to have an elastic core (nitinol) for conducting axial vibrations (sonic or ultrasonic) and a thin stiff cladding (stainless steel) in order to minimize traverse vibrations which result in loss of energy.
