A catheter-insertion assembly includes a catheter with a proximal end and a distal end, a needle with a proximal end and a beveled distal end forming a sharp distal point, and an obturator with a proximal end and a distal end. The distal end of the obturator includes at least one bend. The bend allows the distal end of the obturator to protect the catheter from the sharp distal point of the needle during insertion of the needle through the catheter.
