Abstract
The ultrasonic angioplasty transmission wire for use in an ultrasonic angioplasty device comprises an inner layer of a first ultrasound transmitting material, and at least one outer coaxial shell or tube of a second ultrasound transmitting material different from the first ultrasound transmitting material. The first inner layer and one or more of the outer coaxial shells or tubes can be formed of ultrasound transmitting metal compositions such as stainless steel, nickel-titanium, or aluminum, or other similar suitable ultrasound transmitting metals. In one embodiment, the first inner layer is formed of a nickel-titanium alloy, and at least one outer coaxial shell or tube is formed of stainless steel. In another embodiment, the first inner layer is formed of nickel-titanium alloy, a first outer coaxial shell or tube is formed of stainless steel, and a second outer coaxial shell or tube is formed of the nickel-titanium alloy.
