Abstract: An example introducer is disclosed. An example introducer includes an inner liner including a lumen, a distal region and at least one folded portion extending along the distal region. The introducer also includes a reinforcing member having a length and including at least one spine extending along the length of the reinforcing member. The introducer also includes a sheath disposed along at least a portion of the introducer, wherein the sheath includes at least one perforation, wherein material adjacent to the at least one folded portion is removed from a distal portion of the introducer to form a tip region. The introducer also includes a tip member disposed along the tip region.

Abstract: An expandable sheath may include an inelastic compliant membrane having a lumen therethrough, and a discontinuous outer member bonded to the membrane. The membrane may include one or more folds formed therein. At least a portion of the outer member may extend continuously around a circumference of the membrane in a first configuration. The outer member may be configured to separate to a second configuration when subjected to a radially outward force from within the membrane. The outer member may taper from a first diameter adjacent a proximal hub to a second smaller diameter at a distal end. A method of manufacturing an expandable sheath may include forming one or more folds in a compliant membrane, cutting a plurality of apertures through a wall of an outer covering; and laminating the outer covering onto the membrane, wherein the plurality of apertures is disposed over the one or more folds.
