1. A catheter comprising a needle arranged for creating a puncture suitable for a TIPS shunt, comprising:
a flexible catheter body having a proximal and a distal end, the needle being provided at the distal end of the flexible catheter body,
an actuator arranged for vibrating the needle, and
the needle being provided with serrations on an outer surface, the serrations reducing a piercing force for creating the puncture with the needle when vibrated.
