Abstract: An expandable introducer includes a hub and a tubular sheath (121) coupled thereto. The tubular sheath (121) defines a central lumen (103). A circumference of the tubular sheath includes a full thickness region (162) having a first wall thickness (T2) and a reduced thickness region (161) having a second wall thickness (T1) smaller than the first wall thickness (T2). The reduced thickness region (162) is configured to be folded such that the tubular sheath includes an unexpanded, folded state and is configured to expand to an expanded, unfolded state in response to a device passing though the central lumen (103). A first outer diameter of the tubular sheath in the unexpanded, folded state is smaller than a second outer diameter of the tubular sheath in the expanded, unfolded state.
