The catheter includes a central lumen for receiving the needle and guidewire. The lumen includes a distal port and a transverse side port adjacent an intermediate portion thereof which provide open vascular communication from two ports between the central lumen and the vasculature. The needle and guidewire, when integrated with the catheter, extend through the transverse side port wherein a proximal end of the needle extends contiguous to and exterior of a proximal portion of the catheter.
