<p>A pump is provided for a body implantable prosthesis that includes a reservoir maintaining a fluid volume that is transferrable into a cylinder. The pump includes a pump bulb (40), an inlet valve (54), an exhaust valve (56), and an anti-auto inflation (AAI) valve (60). The pump bulb is connected to a pump body that is in fluid communication with the reservoir and the cylinder. The inlet valve is operable to allow a portion of the fluid volume to be drawn from the reservoir and delivered into the pump bulb. The exhaust valve is operable to allow the portion of the fluid volume delivered into the pump bulb to be pumped into the cylinder. The AAI valve is disposed in the pump body and has a seal that is biased to prevent fluid flow from bypassing the pump bulb and flowing from the reservoir to the cylinder.</p> |
