A flow-velocity sensor probe includes a thermistor for generating heat which is placed in a fluid, and a waterproof resin and a metal piece for easily radiating the heat generated by the thermistor. The flow velocity of the fluid is measured continuously from a change of temperature in the thermistor, and the thermistor is provided in close proximity to the metal piece for transmitting the heat to the fluid.

A multi-luminal catheter is characterized in that the cross-sectional shape of each lumen at a connection portion for an extension tube is molded in accordance with the outer shape of the extension tube to be connected. Accordingly, smooth and hermetic connection between a catheter body and the extension tube, that has not been accomplished in the past, can be obtained, and the formation of steps of the lumen which increases fluid resistance can be prevented. This mult-luminal catheter can be produced by pressing a core metal having substantially the same shape as that of the outer shape of the extension tube into each lumen of the catheter body at the connection portion for the extension tube and inserting the connection portion for the extension tube into a molding die while heating it. Higher airtightness and connection strength can be obtained by fitting the connection end of the extension tube into each lumen at the connection portion of the multi-luminal catheter and integrating them by use of a fixing member.

A catheter for measuring a cardiac output includes a catheter tube defining a longitudinal bore therein and having an opening near its distal end, wherein the tube bore is divided into a first lumen for installing therein a thermistor on a proximal side with respect to the opening, a second lumen in communication with the opening, and at least one third lumen. There are provided a first partition separating the first lumen and the third lumen and a second partition separating the second lumen and the third lumen, the first partition being separate from the second partition.
