First Claim
Patent Images
1. An exploration device to monitor the penetration of an instrument in an anatomic structure comprising:
- at least two electrodes;
a source of voltage supplying the at least two electrodes;
a means for measuring impedance of the anatomic structure between the electrodes;
a means of angular location formed by at least one electrode punctually coinciding with a peripheral surface of the penetration instrument, the coinciding surface of the electrode having a position set off from a longitudinal axis the instrument; and
means for detecting an angular position of the at least one electrode.
