1. A usable-length-selectable catheter system (100) comprising:
a catheter (110) comprising a catheter shaft (115) and a kink protection sleeve (118);
a lock-grip (120);
a mandrel (130) with a handle; and
two or more guide-wire exit ports (113, 116), disposed laterally at
different axial positions of the catheter shaft (115);
characterized in that the mandrel (130) comprises a tip (131) shaped as a deflection surface that is configured to be selectively positioned relative to each one of the two or more guide-wire exit ports (113, 116) such that when a guide- wire (140) impinges on the deflection surface of the mandrel tip, the guide-wire can be reversibly guided through a selected guide-wire exit port;
wherein a usable length of said catheter shaft is variably adjustable between a position of (1) a first and a second of said two or more guide-wire exit ports; and (2) said second guide-wire exit port and a tip of the kink-protection sleeve.
