Abstract
A catheter and introducer needle assembly is provided including a catheter adapter at its proximal end. The catheter adapter includes a side port in fluid communication with the catheter and a septum located in the proximal end of the catheter adapter proximal of the side port. The introducer needle is connected at its proximal end to a needle hub and includes at least one notch in communication with the introducer needle lumen. The notch allows blood to flow into the open distal end of the needle and through the notch into the catheter lumen (specifically, the annular space between the outside of the introducer needle and the inside of the catheter and catheter adapter). Thereafter, the blood can flow through the annular space and then through the side port and extension tube that extends from the catheter adapter.
