- the inflatable member 210 when the inflatable member 210 is being inflated, there may be a higher pressure on at the reservoir 216 than at the inflatable member 210. In such cases, passive filling of the inflatable member 210 may be used. For example, in such cases, the second valve 224 may be opened to allow fluid to flow from the reservoir 216 to the inflatable member 210 without having to operate the second pump 234.
