Rapid Insertion Integrated Catheter and Method of Using an Integrated Catheter

摘要

An integrated catheter assembly for rapid vascular insertion including a catheter configured for receipt of a needle and a guidewire; a catheter assembly comprising an integrated assembly comprising a catheter, needle, and guidewire; and a method of rapidly inserting a catheter to obtain vascular access. 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.

1. A catheter assembly for rapid insertion into a vessel comprising:
a needle having a proximal and distal end, said distal end defining a distal tip for subcutaneous and vessel insertion, and a longitudinally extending guidewire receiving channel; a guide having a proximal and distal end 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 needle so as to extend distally beyond the distal tip of said needle; a catheter having a proximal and distal end and a first longitudinal length defined between said catheter proximal and distal ends and a longitudinally extending first lumen extending between said proximal and distal ends and configured to receive said needle, wherein said distal end of said 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, 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.
