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.

[ What is claimed is:] [1.]1. An ultrasound medical device comprising:a source of ultrasound energy, and an elongated wire-form for transmission of ultrasound energy, said wire-form having a proximal portion, a distal portion, and a length therebetween, said wire-form including along its length a sheath surrounding and contacting a metal core where said sheath and said metal core are formed of different materials, wherein said core and said sheath are bonded at points where said core contacts said sheath.
