Abstract
An implantable fluid operated device includes a fluid control system to transfer fluid between a fluid reservoir and an inflatable member. The fluid control system includes at least one fluid control device including at least one pump and at least one valve, or at least one combination pump and valve device. A seal is provided in the at least one fluid control device. In a first mode, the seal provides a seal between a fluid passageway and a fluid chamber of the fluid control device, to close the fluid control device. In a second mode, the seal is disengaged to open the fluid control device and allow fluid to flow between the fluid passageway and the fluid chamber. A seal retention device maintains a position of the seal when the fluid control device is open and fluid is flowing through the fluid control device.
