An ultrasound catheter comprises an elongate tubular body. 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 diameter. The ultrasound catheter further comprises an elongate, hollow inner core extending through the central lumen. The elongate, hollow inner core has an inner core outer diameter that is less than or equal to the central lumen diameter. 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. The ultrasound catheter further comprises at least two electrical conductors extending between the tubular body proximal region and the tubular body distal region. The at least two electrical conductors are positioned between the tubular body and the inner core. The at least two electrical conductors are electrically connected to the ultrasound radiating member. The at least two electrical conductors are wrapped around the inner core a plurality of times in a region between the ultrasound radiating member and the tubular body proximal region.

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.

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.

A catheter for delivering ultrasonic energy and therapeutic compounds to a patient's vascular system comprises an elongate outer sheath having an energy delivery section. The catheter further comprises an elongate inner core configured to be inserted into the elongate outer sheath. The elongate inner core is positioned at least partially within the energy delivery section. The catheter further comprises a plurality of ultrasound radiating members mounted along the portion of the elongate inner core within the energy delivery section. Each of the ultrasound radiating members is spaced longitudinally from the other ultrasound radiating members. The catheter further comprises an elongate drug lumen configured to deliver a therapeutic compound to the portion of the patient's vascular system adjacent to the energy delivery section.

A catheter system for delivering ultrasonic energy to a treatment site within a body lumen 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 further comprises an inner core configured for insertion into the tubular body. The inner core comprises a first ultrasound radiating member axially separated from a second ultrasound radiating member by an intermediate flexible joint region. The inner core further comprises an electrically conductive portion configured to allow a voltage difference to be applied to at least one of the ultrasound radiating members. The inner core further comprises a high impedance cap positioned proximal to at least one of the ultrasound radiating members.
