Catheter with multiple ultrasound radiating members
First Claim
1. An ultrasonic 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;
a fluid delivery lumen extending at least partially through the tubular body and having at least one outlet in the treatment zone;
a voltage source, wherein the voltage source is attached to at least one wire;
a plurality of ultrasound radiating members positioned in the treatment zone, wherein the plurality of ultrasound radiating members are allocated into electrical groups comprising more than one ultrasound radiating members, and wherein the electrical groups are connected to the at least one wire in series; and
a control system configured to independently drive each group of ultrasound radiating members.
