Abstract
A catheter includes a catheter tube and a Flexible Printed Circuit Board, FPCB, wherein the FPCB covers essentially the catheter circumference for predetermined FPCB transducer segment length, especially at the distal portion, wherein the FPCB in the FPCB transducer segment includes a scaffold structure with a plurality of FPCB free spaces and one FPCB free surface portion creating maximum mechanical stability with the least amount of material and a FPCB scaffold structure which ensures maximum flexibility. The FPCB includes transducer patches which are connected by traces on the straight scaffolds of the scaffold structure. The FPCB free spaces are configured for preventing, circumventing and/or compensating the kinking behavious of the catheter tube.
