Abstract
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 device further includes a dilator and a medical article. A track can extend in a proximal direction from the dilator. The needle hub can slide along at least a portion of the track between a first position and a second position. The device can further include a locking mechanism operably disposed between the track and the needle hub so as to inhibit further axial movement of the needle in the proximal direction when the needle hub is in the second position. The device can further include a guidewire that can bend such that the guidewire can both pass through the needle hub at one end and attach to the needle hub at another end.
