Abstract
A medical probe such as a catheter (20) is guided within the body of a patient by determining the relative positions of the probe relative to another probe, as by transmitting non-ionizing radiation to or from field transducers (30, 230) mounted on both probes. In one embodiment, a site probe (28) is secured to a lesion within the body, and an instrument probe (200) for treating the lesion may be guided to the lesion by monitoring relative positions of the probes. Two or more probes may be coordinated with one another to perform a medical procedure.
