Abstract
The ultrasonic angioplasty transmission wire has regions of reduced cross-sectional diameter to improve flexibility of the ultrasonic angioplasty transmission wire and to compensate for degradation of longitudinal displacement due to acoustic losses along the length of the ultrasonic angioplasty transmission wire. One or more constraining members are disposed on the ultrasonic angioplasty transmission wire at one or more of the regions of reduced cross-sectional diameter where transverse vibration of ultrasonic energy transmitted by the ultrasound transmission wire is amplified, to constrain transverse vibration at these areas to reduce stress and reduce fracturing, while allowing longitudinal movement. The transmission wire has an elongated shaft including, in atomic percent, from about 28 to about 52 percent nickel, from about 48 to about 52 percent titanium, and up to about 20 percent of at least one alloying element selected from the group consisting of palladium, chromium, and hafnium.
