  • a) inserting an elongate ultrasound transmission member through the lumen of said catheter;

    b) connecting said elongate ultrasound transmission member to an ultrasound generating system operative to generate ultrasound energy within the frequency range of 10-1000 kHz; and

    ,c) passing ultrasonic energy within the frequency range of 10-1000 kHz through said ultrasound transmitting member to effect treatment of said vasospasm adjacent the distal end of said catheter body.
