CATHETER WITH MULTIPLE ULTRASOUND RADIATING MEMBERS

摘要

A catheter system 10 for delivering ultrasonic energy to a treatment site includes a tubular body 12 having a proximal end, a distal end and a treatment zone 18 located between the distal end and the proximal end. An ultrasonic assembly 42 is positioned within the treatment zone 18 and provides providing an average longitudinal power density between about.2 and about 1.0 W/cm within the treatment zone 18.
