Abstract

According to an aspect, an inflatable penile prosthesis includes a reservoir configured to hold fluid, an inflatable member, and a pump assembly configured to facilitate a transfer of a fluid from the reservoir to the inflatable member. The pump assembly includes a pump bulb, and a valve body defining a fluid passageway. The valve body includes a refill valve disposed in the fluid passageway. The refill valve includes a valve member. In response to the pump bulb being compressed, the valve member moves within the fluid passageway in a first direction to a closed position in which the valve member blocks the fluid from being transferred around the refill valve. In response to the pump bulb being uncompressed, the valve member moves within the fluid passageway in a second direction to an open position in which the valve member allows the fluid to transfer around the refill valve.
