20. An inflatable penile prosthesis, comprising:
a fluid reservoir configured to hold fluid;
an inflatable member; and
a pump assembly configured to transfer the fluid between the fluid reservoir and the inflatable member, the pump assembly including a pump bulb, a valve body, a valve disposed within the valve body, a first fluid port configured to be fluidly coupled to the fluid reservoir, and a second fluid port configured to be fluidly coupled to the inflatable member, the valve being configured to move between an inflation position and a deflation position,
wherein the valve body includes a sealing surface configured to engage the valve to form seal, the valve body includes a first slot disposed adjacent the sealing surface, the valve body includes a second slot disposed adjacent the sealing surface, the sealing surface being disposed between the first slot and the valve, the sealing surface being disposed between the second slot and the valve, the sealing surface of the valve being disposed between the second fluid port and the slot,
wherein the pump assembly includes a biasing member, the biasing member being configured to bias the valve towards the sealing surface.
