Abstract: An intravenous delivery system includes a device head and a needle carrier. The device head includes a body defining a first lumen extending from a first end to a second end and a second lumen in fluid communication with the first lumen and a port defined by the head body. A catheter disposed at the first end of the head body is in fluid communication with the first lumen. A self-sealing plug is disposed at the second end. The needle carrier is secured to the second end of the head body and includes a longitudinally extending housing and a hollow needle slidably disposed therein. A needle retractor coupled to the needle is operable to slide the needle longitudinally among deployed and retracted positions. The needle extends through the plug, first lumen, and catheter while in the deployed position, and is retracted into the needle carrier housing in the retracted position.
