Bi-directional valve pump

A pump assembly for an inflatable penile prosthesis comprising:

• a valve body including a bi-directional valve;
• a plurality of fluid transfer ports extending from the valve body, the plurality of fluid transfer ports including a reservoir fluid port and at least one cylinder fluid port;
• a pump bulb extending from the valve body;
• and
• a first deflation mode actuator moveably coupled to the valve body,
• a second deflation mode actuator movably coupled to the valve body,
• the bi-directional valve configured to move from an inflation position to a deflation position in response to an activation of the first deflation mode actuator,
• the bi-directional valve in the inflation position configured to open a fluid passageway from the pump bulb to the at least one cylinder fluid port,
• the bi-directional valve in the deflation position configured to open a fluid passageway from the reservoir fluid port to the at least one cylinder fluid port that bypasses the pump bulb.

A method for controlling a direction of fluid through a pump assembly of an inflatable penile prosthesis, the method comprising:

• transferring, by a pump assembly, fluid from a fluid reservoir to an inflatable member, including:
• transferring the fluid from the fluid reservoir to a pump bulb via a refill valve;
• and
• transferring the fluid from the pump bulb to the inflatable member via an inflation valve and a bi-directional valve;
• moving the bi-directional valve to a deflation position in response to activation of a first deflation mode actuator or a second deflation mode actuator;
• and
• transferring the fluid from the inflatable member to the fluid reservoir via the bi-directional valve such that the fluid is not transferred through the pump bulb.
