Abstract: A catheter device comprises a measuring device for measuring a force effect on the catheter device. The measuring device comprises a force transducer comprising a plurality of transducer sections and an optical fiber arranged on the force transducer, wherein the transducer sections form at least a pair of adjacent transducer sections which are connected to one another by means of a connecting section and which can be moved relative to one another with deformation of the connecting section, and wherein the optical fiber comprises at least one sensor device for measuring a force effect between the transducer sections of the at least one pair of adjacent transducer sections. The at least one sensor device comprises a first optical grating and a second optical grating for measuring a force effect between the transducer sections of the at least one pair of adjacent transducer sections.

Abstract: A catheter device comprises a measuring device for measuring a force effect on the catheter device. The measuring device comprises an elastically deformable transducer body with a plurality of transducer portions and a sensor device arranged on the transducer body. The transducer portions form at least one pair of adjacent transducer portions, which are connected to each other via a connecting portion and are movable relative to each other with deformation of the connecting portion. The sensor device is designed to measure a force effect between the transducer portions of the at least one pair of adjacent transducer portions. The transducer body is made of a glass material.
