Abstract
An expandable introducer includes an introducer hub and an introducer sheath coupled to the introducer hub and extending distally therefrom. The introducer sheath includes a sheath wall, the sheath wall having an interior surface defining a lumen of the introducer sheath and an exterior surface disposed radially outward from the interior surface. The exterior surface may be wavy or ridged to reduce contact surface area between the introducer sheath and a patient's anatomy. The interior surface of the sheath wall may be wavy or ridged to reduce contact surface area between the sheath wall and a dilator and/or delivery system that advances therethrough. The exterior surface of the sheath wall may be textured to aid in hydro-coat retention and/or to reduce surface contact area with a patient's anatomy, thereby reducing track forces during insertion and delivery. The introducer sheath wall may include a spine.
