Abstract
A stent is placed in a tubular structure of the anatomy such as the vascular or respiratory system by advancing a probe bearing the stent into the body. The disposition of the probe, and hence the disposition of the stent are monitored using a system which transmits non-ionizing fields between a transducer or transducers on the probe and external transducers. The disposition of the stent relative to the tubular structure is depicted showing a representation of the stent superposed on an image of the tubular structure. This provides accurate placement, particularly for complex stents with features such as one or more branches which must be aligned with anatomical features.
