Zusammenfassung:An introducer needle can include a needle shaft, a sheath over the needle shaft, and a needle hub around a proximal portion of each of the needle shaft and the sheath. The needle shaft can include a needle slot extending from the proximal portion of the needle shaft through a distal needle tip, which needle tip can include a bevel having a tip bevel and a heel. The needle shaft can include opposite needle-slot walls that either: a) face each other and are parallel or oblique to each other, or b) face toward or away from a bottom of the needle slot. Additionally or alternatively, opposite needle-shaft walls can be parallel to each other. The sheath over the needle shaft can seal the needle slot thereunder but for a sheath opening in a proximal portion of the sheath.
