Abstract
Fatty artherosclerotic plaque, under heat (e.g. by applied microwave radiation) and pressure, is liquified and sucked into the interior of one of two catheters of a catheter arrangement through an aperture therein and then sucked out of a patient's body through the proximal end of the one catheter. The other of the two catheters employs an inflated balloon to press the aperture region of the one catheter firmly against the plaque portion to be removed. Calcified artherosclerotic plaque can be ablated and removed in a similar manner, by substituting ultrasonic energy for heat.
