A vascular introducer (50) having an expandable sheath (56). The sheath (56) includes a balloon-expandable section (68) and a self-expandable section (70), where the balloon-expandable section (68) is distal to the self-expandable section (70). The distal balloon-expandable section (68) is collapsible to decrease a diameter of the introducer (50) for directing the introducer (50) into a vasculature of a patient.
