Abstract: An example dilator is disclosed. The example dilator includes a hub and an elongate shaft having a distal end region, a proximal end region and a cross-sectional profile. Additionally, the proximal end region of the elongate shaft is coupled to the hub and the elongate shaft is configured to extend through at least a portion of a lumen of an expandable introducer sheath. Additionally, the cross-sectional profile of the elongate shaft includes at least one engagement portion and at least a portion of the expandable introducer sheath extends into the at least one engagement portion of the dilator.

Abstract: An introducer may include a layered tubular member having an inner liner including at least one folded portion extending along a distal region of the inner liner in a delivery configuration; a reinforcing member disposed over at least a portion of the inner liner, the reinforcing member including a plurality of longitudinal spines defining a plurality of openings disposed between adjacent longitudinal spines, wherein each folded portion is circumferentially overlapped by one of the plurality of openings; and an outer sheath disposed over the reinforcing member, wherein the outer sheath includes at least one perforation circumferentially overlapping each folded portion; and a tip member fixedly attached to a tapered distal region of the layered tubular member. The inner liner may extend to a distal end of the layered tubular member. At least a portion of each folded portion may terminate proximal of the distal end of the layered tubular member.
