Abstract
The invention relates to a catheter device with an integrated fiber optic, in particular for use in thermodilution measurement and pulse contour analysis. The device comprises an arterial catheter (2) with a suitable intravascular part and a suitable extravascular part and an optical sensor unit for combined pressure and temperature measurement at a measurement location at the distal end of the suitable intravascular part or proximate to the distal end of the proper intravascular part of the catheter (2). The optical sensor unit comprises a fiber optic conductor (11) that runs from the measurement location to a proximal port.
