Abstract:
1. A method of manufacturing an ultrasonic catheter comprising: providing an inner tube having an inner diameter sufficient to accommodate a guidewire; mounting a tubular ultrasound radiating member around a distal region of the inner tube; positioning a first and a second electrical conductor along the inner tube, such that the first electrical conductor contacts an inner side of the ultrasound radiating member, and the second electrical conductor contacts an outer side of the ultrasound radiating member; concentrically translating an outer tube over the inner tube and the ultrasound radiating member; and radially shrinking the outer tube onto the inner tube, so that the first and the second electrical conductors are located in between the inner tube and the outer tube along the length of the ultrasonic catheter.
