SENSING BIOPSY NEEDLE

The system and method for characterizing a tissue of interest may include navigating a needle device in proximity to the tissue of interest. The needle device can comprise a member including a plurality of electroconductive segments. The plurality of electroconductive segments can be electrically insulated from one another. The device can also include a first conductive path electrically coupled to a first electroconductive segment. A second conductive path can be coupled to a second electroconductive segment. The method can include contacting the tissue of interest with the first electrode and determining a tissue impedance of the tissue of interest from an electrical signal from the first electrode. The method can also include characterizing the tissue of interest as malignant or benign based on the tissue impedance.
