A self-priming pulsatile surgical irrigation device is disclosed. The irrigation device comprises a housing, a variable volume pumping chamber liquid pump contained within the housing, and a self-priming valve system operatively associated with the liquid pump. The self-priming valve system, which facilitates the priming of the device, includes a valve housing, a liquid inlet to admit liquid into the valve housing and a liquid outlet to emit liquid from the housing. The housing is configured to define a flow path that directs liquid from the liquid inlet into the pumping chamber. The flow path ensures that the pumping chamber is maintained full during operation of the pump.
