Abstract

Catheter-based devices (10) for measuring tissue temperature at a number of sites. In particular, the present invention relates to catheter-based devices (10) that are able to measure tissue temperature and thermal heterogeneity in the tissue to help determine the presence of inflammation of the tissues. In addition, the present invention relates to catheter devices that, if used in arteries, veins, or compartments of the heart to measure tissue temperature, do not seriously compromise blood flow through the vessel during the measurement.
