1. A method of preventing inflation of an implantable prosthetic comprising the steps of:

  • biasing a valve assembly such that an outlet is substantially closed;

    using pressure increases from the inlet to supplement the biasing of the valve assembly and to prevent fluid flow through the outlet by selectively varying fluid pressure within a bypass passageway having a first end which is in fluid communication with an inlet and a second end which is in fluid communication with a chamber; and

    displacing a flexible abutting wall disposed between the chamber and the valve assembly so that the abutting wall is caused to contact the valve assembly and urge the valve assembly into a closed position when the fluid pressure within the chamber exceeds a predetermined amount.
