An introducer sheath that can include an elongate tubular member, such as a metallic tubular member, including a tubular wall defining a lumen and including a proximal portion and a distal portion. In some embodiments, a portion of the tubular member, such as the distal portion, can include a plurality of apertures defined in the tubular wall, and another portion, such as the proximal portion, can be free of apertures defined in the tubular wall. The portion including the apertures defined therein can be more flexible than the portion free of the apertures. A second tubular member can be disposed on or within the elongate tubular member, and can define a fluid tight pathway through the lumen. Additionally, a hub can be attached to the proximal portion of the elongate tubular member and in fluid communication with the fluid tight pathway.
