Inflatable penile prosthesis with valves for increasing flow efficiency

A valve assembly for an inflatable penile prosthesis, the valve assembly comprising:

• a valve body having a first fluid passageway for transfer of fluid between a reservoir and a pump bulb and a second fluid passageway for transfer of fluid between the pump bulb and an inflatable member;
• a refill valve disposed in the first fluid passageway, the refill valve having a valve member, wherein in response to the pump bulb being compressed, the valve member is configured to move within the first 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, wherein, in response to the pump bulb being uncompressed, the valve member is configured to move within the first fluid passageway in a second direction to an open position in which the valve member allows the fluid to transfer around the refill valve;
• and
• an inflation valve disposed in the second fluid passageway.

An inflatable penile prosthesis comprising:

• 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 including a pump bulb, and a valve body defining a first fluid passageway and a second fluid passageway, the valve body including a refill valve disposed in the first fluid passageway, and an inflation valve disposed in the second fluid passageway,
• at least one of the refill valve and the inflation valve including a flapper valve.
