Beschreibung
Zusammenfassung:	An expandable sheath including an elongated inner member defining a central lumen extending therethrough. The inner member includes a first circumferential portion including a first and second longitudinal edges, and a second circumferential portion extending between the first and second longitudinal edges. The wall thickness of the first circumferential portion is greater than the wall thickness of the second circumferential portion. The elongated inner member is configured to transition from an unexpanded configuration to an expanded configuration in response to a radially outward force on an inner surface of the central lumen. In the unexpanded configuration, the elongated inner member is creased proximate the first and second longitudinal edges into a folded configuration such that the second circumferential portion is positioned at least partially radially inward of the first circumferential portion.
