A catheter system for delivering ultrasonic energy to a treatment site within a body lumen, the catheter comprises a tubular body having a proximal end, a distal end and an energy delivery section positioned between the proximal end and the distal end and a plurality of ultrasound radiating members in the energy delivery section. The plurality of ultrasound radiating members are allocated into electrical groups comprising more than one ultrasound radiating member. Members of one electrical group are spatially interdigitated with members of another electrical group.

Ultrasound system

A method of delivery ultrasonic energy and a therapeutic compound to a treatment site and an ultrasonic catheter system are disclosed. The ultrasonic catheter system comprises a tubular body having a proximal end, a distal end and a treatment zone located between the distal end and the proximal end, a fluid delivery lumen, at least one ultrasound radiating element positioned in the treatment zone, wiring electrically coupled to the at least one ultrasound radiating element and extending through the tubular body and terminating at a connector, and a control system comprising external circuitry and an isolation pod that is configured to be electrically connected to the connector, the isolation pod being positioned between the tubular body and the external system and comprising an isolation barrier and circuitry for driving the ultrasound radiating element.

Catheter with multiple ultrasound radiating members

An ultrasound catheter with a lumen for fluid delivery and fluid evacuation, and an ultrasound source is used for the treatment of intracerebral or intraventricular hemorrhages. After the catheter is inserted into a blood clot, a lytic drug can be delivered to the blood clot via the lumen while applying ultrasonic energy to the treatment site. As the blood clot is dissolved, the liquefied blood clot can be removed by evacuation through the lumen.

Method and apparatus for treatment of intracranial hemorrhages

A catheter control system the system can include a control unit having a first connection port. The control unit can have a first visual indicator associated with the first connection port. The system can also include a first catheter interface connector connected to the first connection port of the control unit. The first catheter interface connector can have a first visual indicator corresponding to the first visual indicator on the control unit. The first visual indicator on the first catheter interface connector can be to be active to indicate that the first catheter interface connector is connected to the first connection port on the control unit.

Method and apparatus for drug delivery to a target site

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.

A central venous catheter comprises an ultrasound assembly. In one arrangement, the radiating member is used to remove a blockage from the central venous catheter. In another arrangement, inserting an ultrasound assembly into a central venous catheter. The ultrasound assembly comprises an ultrasound radiating member mounted on an elongate support structure. The method further comprises positioning the ultrasound assembly within the central venous catheter such that the ultrasound radiating member is adjacent to a deposited material formed on a portion of the central venous catheter. The method further comprises supplying an electrical current to the ultrasound radiating member to expose the deposited material to ultrasonic energy. The method further comprises passing a therapeutic compound through the central venous catheter to expose the deposited material to the therapeutic compound simultaneously with ultrasonic energy.
