1. An apparatus, comprising:
a connector having a distal piece and a proximal piece, wherein the distal piece and the proximal piece are coupled together in a snap fit or an interference fit, a distal end of the distal piece of the connector having a male luer adapter configured to couple with a proximal end of a catheter adapter, a proximal end of the proximal piece of the connector having a female luer adapter; and
a catheter secured within the distal piece of the connector, the catheter extending from the distal end of the distal piece of the connector, the catheter having a closed distal end and a slit adjacent the closed distal end, wherein the slit is closed under normal physiological pressures, wherein the proximal piece comprises a tubular element snugly inserted inside the proximal end of the catheter, the tubular element having an outer diameter slightly less than an inner diameter of the catheter;
a guidewire hub comprising a male luer adapter removably coupled to the female luer adapter of the proximal piece of the connector; and
a guidewire having a proximal end and a distal end, the guidewire extending from the distal end of the guidewire hub and disposed within the catheter, wherein the proximal end of the guidewire is secured within the guidewire hub.
