Abstract
At least one embodiment of the invention relates to a catheter arrangement comprising a catheter with a proximal section and a distal section, to measure a force acting on the distal section and simultaneously receive a temperature signal prevailing in the distal section. According to at least one embodiment of the invention, the catheter arrangement comprises an evaluation unit connected to a single combined optical force and temperature sensor, and further comprises a readout signal generator to generate and feed a readout signal modulated with a carrier frequency into the force sensor and temperature sensor. According to at least one embodiment of the invention, the catheter arrangement comprises a first readout device to read out a first modulated measuring signal portion, a second readout means to read out a second unmodulated measuring signal portion, and a processing unit to combine the first and second measuring signal portions.
