A method of excavating tissue in the body, including bringing a catheter (60) to a location, injecting microbubbles (84) at the location and causing cavitation of tissue (76) at the location using ultrasound. Preferably, the microbubbles (84) are injected directly into the tissue, such as by using a hollow needle (62). Alternatively, microbubbles (84) are injected into the vascular bed of the tissue at the location, so that the capillaries (86) are infused with microbubbles (84).

[ What is claimed is:] [5.]5. A method of excavating within a generated magnetic field comprising:(a) bringing a probe to a location, the probe comprising a probe body having a distal tip, a position sensor near the distal tip wherein the position sensor is a magnetic field receiver which determines the position of the tip by sensing the instantaneous position of the tip from a generated magnetic field and a source of microbubbles;(b) injecting microbubbles at the location; and(c) causing cavitation of tissue at the location using ultrasound.
