A device configured for being implanted in a male patients body for assisting the patient to achieve an erection. The device includes at least two rods and an interconnecting structure. The rods can be selectively deployed to the penis shaft when an erection is to be achieved and retracted away from the penis shaft when the patient does not need to achieve an erection. The interconnecting structure is joined to the rods and is configured to stabilize the rods while the rods are in the penis shaft.
