A part to be mounted into force or pressure sensors includes an annular measuring element made of piezoelectric material. First and second electrodes rest against respective opposite sides of the measuring element and are provided with wires. An electrically insulating transmission member laterally adjoins the first electrode, across from the measuring element. Another electrically insulating insulation member laterally adjoins the second electrode, across from the measuring element. All components are mounted within the part in such a way as to be centered relative to each other. The external face of the transmission member and the external face of the insulation member which face away from and run parallel to the electrodes are designed in a very planar manner, having a levelness of less than 10 &#x3bc;m.

Part for measuring forces or pressures, and sensor comprising such a part

The present invention relates to a catheter having a soft distal tip that can be manufactured at lower cost than catheters in the prior art. In one embodiment, the catheter is produced by coupling a soft sleeve to the distal end of a catheter tube. The sleeve may affixed to the catheter tube under temperature and pressure conditions that cause the proximal end of the sleeve to taper against the outer surface of the catheter tube, avoiding or minimizing discontinuities in the insertion profile of the catheter, and that also cause the inner wall of the sleeve to taper against the distal end of the catheter tube, avoiding or minimizing discontinuities in the lumen of the catheter.
