Abstract:
1. A device for assessing composition of a plaque, the device comprising: an elongate body having a longitudinal axis and a distal end; a first excitation electrode and a second excitation electrode located along the longitudinal axis of the body; and a first detection electrode and a second detection electrode along the longitudinal axis of the body and in between the first and second excitation electrodes; wherein when a current source in communication with at least one of the first excitation electrode and the second excitation electrode applies current thereto to facilitate measurement of two or more conductance values within a vessel containing at least part of the elongate body at a plaque site, a plaque type determination from at least two types of plaques to distinguish one plaque type from another can be made based upon a calculation of tissue conductance using at least one of the two or more conductance values obtained by the device configured to obtain said values.
