Abstract

According to an aspect, an inflatable penile prosthesis includes 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 includes a valve body, a pump bulb, and a deflation mode actuator. The valve body includes a bi-directional valve configured to move from an inflation position to a deflation position in response to an activation of the deflation mode actuator. The bi-directional valve in the inflation position is configured to open a fluid passageway in the valve body to transfer fluid from the pump bulb to the inflatable member. The bi-directional valve in the deflation position is configured to open a fluid passageway in the valve body to transfer fluid from the inflatable member to the fluid reservoir that bypasses the pump bulb.
