Abstract: An example introducer is disclosed. An example introducer sheath includes a tubular member including an inner surface, an outer surface and a wall extending therebetween. The introducer further includes a plurality of spine members. The plurality of spine members are positioned radially inward of the outer surface of the tubular member. Further, each of the plurality of the spine members are positioned radially outward of the inner surface of the tubular member. Additionally, the tubular member is designed to shift from a first configuration to a second configuration and the wall has a first thickness in the first position and a second thickness in the second position, the second thickness smaller than the first thickness.

Abstract: An introducer sheath may include a tubular member comprising an inner layer and an outer layer coaxially disposed about a central longitudinal axis of the introducer sheath, the tubular member being configured to shift between an unexpanded configuration to an expanded configuration. The inner layer may be circumferentially discontinuous along at least a portion of its length. At least a first portion of the inner layer may be configured to move circumferentially relative to the outer layer when shifting between the unexpanded and expanded configurations.

Abstract: An introducer may include a layered tubular member having an inner liner including at least one folded portion extending along a distal region of the inner liner in a delivery configuration; a reinforcing member disposed over at least a portion of the inner liner, the reinforcing member including a plurality of longitudinal spines defining a plurality of openings disposed between adjacent longitudinal spines, wherein each folded portion is circumferentially overlapped by one of the plurality of openings; and an outer sheath disposed over the reinforcing member, wherein the outer sheath includes at least one perforation circumferentially overlapping each folded portion; and a tip member fixedly attached to a tapered distal region of the layered tubular member. The inner liner may extend to a distal end of the layered tubular member. At least a portion of each folded portion may terminate proximal of the distal end of the layered tubular member.

Abstract: Catheters with weeping balloons can be used for various medical purposes. For example, in some embodiments provided herein weeping balloons are used for catheter visualization devices. In some embodiments, weeping balloons are used to deliver therapeutic agents. Weeping balloons can include openings of a selected size and shape through which a fluid gradually flows or “weeps.” The design of the openings can affect performance characteristics such as, but not limited to, fluid flow rate, tear resistance, and mitigation of counter-flow.
