Abstract
An ultrasound catheter (10) for removing obstructions from tubular anatomic structures such as blood vessels, said catheter comprising an elongate flexible catheter body (20) having an ultrasound transmission member or wire (24) extending longitudinally therethrough. A distal head (26) is formed on the distal end member of the ultrasound transmission member or wire (24) and is affixed to the catheter body (20). 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 (24) 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 member connector (12) may be provided with a sonic connector to effectively couple the catheter (10) to the ultrasound transducer (14).
