An access device places a medical article within a body space of a patient. The device has a needle that includes an elongated body and a needle hub. The medical article is disposed over and slideable over the needle. A flash space is provided anywhere between the needle and the outer surface of the medical article. The flash space communicates with a bore of the needle, as well as a variable volume chamber. The variable volume chamber can then draw fluid from the flash space into the chamber. Image
