The force measurement at the instrument tip during minimally invasive interventions can not only reduce the risk of complications, but also reduce the treatment time. This is especially valid for heart catheterization, where a long thin catheter and guide wire are inserted into the coronary vessels for localization and dilation of stenosis. In order to reduce the friction forces in the vascular system, the guide wire is usually coated with biocompatible materials. In this work the influence of the coating material pebax 3533 is being examined to the insulated copper wires which transmit the sensor signal from the distal to the proximal end of the guide wire. The results of this study show that the dissolved pebax has no significant influence to the polyurethane insulation of the copper wires and it can be used as a coating material.
