ACCESS DEVICE

摘要

An access device (20) places a medical article within a body space of a patient. The device has a needle (22) that includes an elongated body and a needle hub (34). The device further includes a dilator (24) and a medical article. A track (30) 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 (44) 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.
