Introducer components, assemblies, and methods thereof

Abstract

Disclosed are introducer components, assemblies, and methods. For example, an introducer assembly can include an access guidewire loaded in a needle assembly fluidly connected to a syringe. The needle assembly can include a needle and a valve thereover. The needle can include a needle shaft including a needle lumen, a needle slot in a proximal portion of the needle shaft, and a needle hub over the proximal portion of the needle shaft but proximal of the needle slot. The valve can be over the needle slot with a valve port aligned with the needle slot. The access guidewire can be loaded in the needle lumen and sealed therein by way of the valve port 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 of a patient upon establishing a needle tract thereto with the needle assembly.
