Catheter with multiple ultrasound radiating members
First Claim
1. A catheter system for delivering ultrasonic energy to a treatment site, the catheter system comprising:
- a tubular body having a proximal end, a distal end and a treatment zone located between the distal end and the proximal end; and
an ultrasonic assembly positioned within the treatment zone;
the ultrasonic assembly comprising a common electrical conductor and a plurality of ultrasonic transducer pairs along the common electrical conductor, each ultrasonic transducer pair comprising a first ultrasound transducer having a first portion, a second ultrasound transducer having a second portion;
wherein the first portion of the first transducer and the second portion of the second transducer face each other and are electrically coupled to the common electrical conductor.

Abstract
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.
