Zusammenfassung:	Disclosed are introducer components, assemblies, and methods. For example, an introducer assembly can include a syringe and a needle assembly fluidly connected thereto. The needle assembly can include a needle and an access guidewire-advancement mechanism mounted on a proximal linear portion of a needle shaft of the needle. The needle shaft can include a sigmoid portion between a distal linear portion of the needle shaft and the proximal linear portion as well as a port in a transition from the sigmoid portion to the distal linear portion of the needle shaft. An access guidewire can be loaded in both the access guidewire-advancement mechanism and a needle-shaft lumen in the distal linear portion of the needle shaft in a ready-to-deploy state of the introducer assembly. In this way, the access guidewire can be immediately advanced into a blood-vessel lumen upon establishing a needle tract thereto with the needle.
