ABSTRACT:
An ultrasonic ablation device for effecting ultrasonic ablation of intravascular obstructions such as plaque or thrombi. The ultrasonic ablation device has a) an elongate catheter body, b) a wave guide or ultrasound transmission wire extending through the elongate catheter body, and c) a distal head or probe member positioned at the distal end of the catheter body. A guidewire lumen or passageway extends longitudinally through the catheter body and a guidewire aperture or passageway extends through the distal head or probe such that a guidewire may be passed through the distal head or probe and through the catheter body. Also disclosed is an improved distal head or probe which may be incorporated in any elongate ultrasonic ablation device, the improvement comprising the formation of a concavity or indentation in the distal or frontal face of the distal head or probe to improve the cavitation created thereby.
