Abstract: An example medical device is disclosed. The example medical device includes a tubular scaffold. The scaffold includes a longitudinal axis, an inner surface and an outer surface. The medical device also includes a flexible valve extending radially inward from the inner surface of the scaffold. The valve includes an annular chamber extending circumferentially around the inner surface of the scaffold and is configured to shift from a closed configuration to an open configuration.

Abstract: This disclosure provides design, material, manufacturing method, and use alternatives for medical devices. An example medical device includes a scaffold including a central member and a plurality of extension members extending away from the central member. The central member includes a plurality of discrete attachment locations corresponding to each of the plurality of extension members and each of the plurality of extension members is pivotably coupled to the central member at a corresponding discrete attachment location. The medical device also includes a covering substantially surrounding the scaffold and an electrode located at a distal end of each of the plurality of extension members. Each electrode extends through at least a portion of the covering.

Abstract: A stent includes a tubular support structure extending from a distal end to a proximal end, the tubular support structure including an inner surface and an outer surface. A retractable anchor system is disposed relative to the tubular support structure and includes a frame member and a plurality of retractable anchors secured to the frame member. The plurality of retractable anchors are biased to a deployed configuration in which the plurality of retractable anchors extend radially outward from the outer surface of the tubular support structure but are radially inwardly compressible into a delivery configuration.
