ULTRASCHALLKATHETER ZUR BESEITIGUNG VON OBSTRUKTIONEN AUS ROHRFÖRMIGEN ANATOMISCHEN STRUKTUREN, WIE BLUTGEFÄSSEN
摘要
An ultrasound catheter for removing obstructions from tubular anatomic structures such as blood vessels, said catheter comprising an elongate flexible catheter body having an ultrasound transmission member or wire extending longitudinally therethrough. A distal head is formed on the distal end of the ultrasound transmission member or wire and is affixed to the catheter body. The ultrasound transmission member or wire may be formed of any material capable of transmitting ultrasonic energy including various superelastic metal alloys such as nickel titanium metal alloys. The distal portion of the ultrasound transmission member or wire may be of reduced diameter to provide enhanced flexibility and/or amplification of the ultrasonic energy through the distal portion of the ultrasound transmission member or wire. A proximal end connector may be provided with a sonic connector to effectively couple the catheter to the ultrasound transducer.
