The retainer are flexible and distensible. They are connected to each other through the stem passage, and are inflatable by fluid injected into them. A leaflet-type fill valve passes through the wall of the proximal retainer. Th fill valve closes when outside pressure is exerted on the leaflets. The fill valve can be physically opened by insertion of a fill tube into it.
