Abstract
An access device for placing a medical article within a body space includes a needle, a dilator, and a medical article. The needle can include an elongated needle body with a distal end and a hub from which the needle body extends. The elongated needle body can include at least one side fenestration and an outer diameter. The dilator can be slideably disposed on the needle body and include a dilator hub and an elongated dilator shaft that extends from the dilator hub. The dilator shaft can include at least one side fenestration in communication with the needle side fenestration. The dilator shaft can also include an inner diameter that is less than the outer diameter of the needle. The medical article can include a tubular section and a hub. The tubular section can be disposed on the dilator and define a space between the medical article and the dilator in communication with the needle side fenestration through the dilator side fenestration. At a least portion of the medical article can be configured to allow visual determination of the presence of a body fluid within the space.
