A tubular first device segment has longitudinally spaced proximal and distal first segment ends. The first device segment includes a first segment lumen. A tubular second device segment has longitudinally spaced proximal and distal second segment ends and a second segment lumen. A tubular eversion structure is located longitudinally intermediate the first and second device segments. The eversion structure has longitudinally spaced proximal and distal eversion ends separated by a tubular eversion structure wall. One of the proximal and distal eversion ends is attached to the first device segment and the other of the proximal and distal eversion ends is attached to the second device segment. At least a portion of the eversion structure wall is configured for selective intussusception into at least one of the first segment lumen, the second segment lumen, and another portion of the eversion structure wall.
