The present disclosure relates to catheterization systems and components thereof. In one embodiment of the present disclosure, a catheterization system is disclosed that includes a catheter including a body with proximal and distal ends and defining first and second lumens extending therethrough, and a stylet. The stylet includes first and second stylet portions each having proximal and distal end regions, wherein the distal end regions of the first and second stylet portions together define a tapered penetrating portion. The first and second stylet portions are configured and dimensioned to be slidably positioned within the first and second lumens of the catheter, respectively.; The first and second stylet portions extend from the proximal end of the catheter and beyond the distal end of the catheter, and are independently movable in relation to each other to facilitate selective removal of the first stylet portion and/or the second stylet portion from the catheter.
