Guidewires curved tips

Simple catheter relocations can be performed with a forceful injection of saline, insertion of guidewire, or transfemoral relocation (Olcott et al. 1989). A transfemoral catheter relocation involves a common femoral vein puncture and the placement of a tightly curved catheter, reversed curved catheter, or catheter with a tip deflecting wire to engage the malpositioned catheter and draw it back into the right atrium. These techniques are used when the catheter length is deemed appropriate and does not need modification.
