Bus-based, miniaturized multi-sensory catheter system

One trend in medical technology is the continuous miniaturization of components, assemblies and complete systems. Such complete systems are functionalized catheters with different sensor and actuator components [1–8]. If even the smallest bottlenecks, for example in blood vessels, are to be reached in the human body, the catheter diameter must be further reduced with the same functionalization. A new approach is chosen, which does not apply the supply and signal lines to the catheter surface or insert them into the existing lumen, but becomes a direct and inseparable part of the catheter. Contacting these conducting tracks with the electronic components is one of the key processes in the manufacture of this type of catheter. A final demonstrator is used for functional testing.
