Claim 15:
16. An inflatable penile prosthesis comprising:
a reservoir configured to hold fluid;
an inflatable member; and
a pump assembly configured to transfer fluid from the reservoir to the inflatable member, the pump assembly comprising a pump bulb, at least one valve, an entry tube configured to provide the fluid to the at least one valve, and an exit tube configured to send the fluid from the at least one valve, the pump bulb being configured to transfer the fluid from the reservoir, through the at least one valve, and to the inflatable member in response to the pump bulb being compressed, the at least one valve comprising:
an entry portion defining an entry portion passageway;
a middle portion adjacent to the entry portion, the middle portion being wider than the entry portion and defining a chamber;
an exit portion adjacent to the middle portion, the exit portion being narrower than the middle portion, the exit portion defining an exit portion passageway and comprising:
a first landing portion extending non-linearly along a length of the middle portion and including an interior portion, the interior portion of the first landing portion being semicircular about a longitudinal exit axis, the longitudinal exit axis extending through a center of the exit portion parallel to a direction that an exit tube interface extends from the exit portion, the interior portion of the first landing portion having a landing arc;
a first channel portion adjacent to the first landing portion and including an interior portion, the interior portion of the first channel portion being farther from the longitudinal exit axis than the interior portion of the first landing portion, the interior portion of the first channel portion having a channel arc, the channel arc of the first channel portion being less than the landing arc of the first landing portion, the first channel portion extending into the middle portion in a direction parallel to the longitudinal exit axis;
a second landing portion adjacent to the first channel portion and including an interior portion, the interior portion of the second landing portion being semicircular about the longitudinal exit axis and having a landing arc that is equal to the landing arc of the interior portion of the first landing portion; and
a second channel portion adjacent to the second landing portion and the first landing portion and including an interior portion, the interior portion of the second channel being farther from the longitudinal exit axis than the interior portion of the first landing portion and the interior portion of second landing portion, the interior portion of the second channel portion having a channel arc that is equal to the channel arc of the first channel portion, the second channel portion extending into the middle portion in a direction parallel to the longitudinal exit axis;

the exit tube interface adjacent to the exit portion, the exit tube interface being configured to attach to the exit tube, the exit tube interface being narrower than the middle portion, the exit tube interface defining an exit passageway; and
a valve member disposed inside the chamber, the valve member being biased to rest against the entry portion.
