Abstract

Catheter for the temperature measurement of vascular walls (artery-vein), or of internal surface of the wall of concave biological organs, which comprises one or more thermistors and either 1) a gas chamber or a liquid chamber whose expansion is achieved by the external application of gas or liquid, or 2) a coil that can be withdrawn and expanded with external manipulations. The thermistor or thermistors are positioned in such a way that they can come in contact with the vessel wall, irrespectively of the diameter of the vascular, or the internal surface of the wall of concave biological organs, as a result of the expansion of the gas chamber or the expansion of the coil.
