    摘要： A catheter for delivering ultrasonic energy and therapeutic compounds to a treatment site within a patient's vasculature comprises a tubular body. The tubular body has a proximal region and a distal region opposite the proximal region. The catheter further comprises a plurality of fluid delivery lumens formed into the tubular body. The catheter further comprises an inner core configured for insertion into the tubular body. The inner core comprises an elongate electrical conductor having a plurality of flattened regions, each flattened region having a first flat side and a second flat side opposite the first flat side. The inner core further comprises a plurality of ultrasound radiating members mounted in pairs to the flattened regions of the elongate electrical conductor. A first ultrasound radiating member is mounted to the first flat side of the elongate electrical conductor, and a second ultrasound radiating member is mounted to the second flat side of the elongate electrical conductor. The catheter further comprises control electronics configured to apply a driving signal to at least two, but fewer than all, of the ultrasound radiating members.

    摘要： A catheter system for delivering ultrasonic energy and a therapeutic compound to a treatment site within a patient's vasculature comprises a tubular body. The tubular body has a proximal end, a distal end and an energy delivery section positioned between the proximal end and the distal end. The catheter system further comprises an inner core configured for insertion into the tubular body. The inner core has an outer surface and comprises an electrically conductive core material. The catheter system further comprises a plurality of ultrasound radiating members positioned on the outer surface of the inner core. The ultrasound radiating members are electrically connected to the electrically conductive core material. The catheter system further comprises an electrically conductive tube-shaped member disposed over the inner core and over the ultrasound radiating members positioned thereon. At least a portion of the electrically conductive tube-shaped member is electrically connected to a plurality of the ultrasound radiating members. The catheter system further comprises control circuitry configured to deliver an input signal to a plurality of the ultrasound radiating members.
