1. A catheter assembly for rapid insertion into a vessel comprising:
a needle having proximal and distal ends, said distal end defining a sharpslistal tip for subcutaneous and vessel insertion, and a longitudinally extending guidewire receiving channel;
a guidewire having proximal and distal ends positioned within said guidewire receiving channel and extending substantially along a longitudinal length of said needle between said needle ends, said guidewire having a length greater than said longitudinal length of said needle so as to extend distally beyond the distal tip of said needle;
a catheter having proximal and distal ends and a first longitudinal length defined between said catheter proximal and distal ends and a longitudinally extending first lumen extending between said catheter proximal and distal ends and configured to receive said needle, wherein a distal end of said first lumen defines a distal port for providing intravenous communication, and wherein said first lumen includes a transverse side port in fluid communication with said first lumen when said transverse side port is devoid of said needle, said first lumen transverse side port being defined by an outer side surface of said catheter wherein said first lumen distal port and said transverse side port provide intravenous communication with said first lumen wherein said needle removably extends through said transverse side port and along a portion of said first lumen.
