摘要： A method of delivery ultrasonic energy and a therapeutic compound to a treatment site and an ultrasonic catheter system are disclosed. The method comprises providing a catheter with a plurality of ultrasound radiating members, wherein the plurality of ultrasound radiating members are allocated into electrical groups comprising more than one ultrasound radiating member. The method further comprises independently driving each group of ultrasonic radiating members, and delivering the therapeutic compound through the catheter to the treatment site.

摘要： An ultrasound catheter comprises an elongate tubular body is disclosed. The elongate tubular body has a proximal region and a distal region opposite the proximal region. The tubular body defines a central lumen having a central lumen surface that is electrically conductive. The ultrasound catheter further comprises an elongate, hollow inner core extending through the central lumen and has an inner core outer surface that is electrically conductive. The ultrasound catheter further comprises an ultrasound radiating member positioned within the distal region of the tubular body and between the tubular body and the inner core, such that the tubular body conductive surface and the inner core conductive surface are both in electrical contact with the ultrasound radiating member. The ultrasound catheter further comprises an insulating sleeve positioned between the tubular body and the inner core in a region proximal to the ultrasound radiating member.
