Catheter with multiple ultrasound radiating members
First Claim
1. An ultrasonic catheter system comprising:
- a tubular body having a proximal end, a distal end, a treatment zone located between the distal end and the proximal end, and at least one fluid delivery lumen incorporated into the tubular body;
a plurality of ultrasound radiating members mounted within an inner core, the inner core is positioned within the tubular body such that at least one of the ultrasound radiating members is located within the treatment zone, whereinthe ultrasound radiating members are allocated into electrical groups,each electrical group comprising more than one ultrasound radiating members, andat least one of the ultrasound radiating members of one electrical group is not positioned adjacent to the other ultrasound radiating members of the same electrical group; and
a control system for independently driving each of the ultrasound radiating members.

Abstract
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.
