An injector assembly for delivering flowable material to a medical implant, including a tube having a first end and a second end, a connector member and a port connector, where the connector member is coupled to the first end of the tube and the port connector is coupled to the second end of the tube, the connector member being configured to attach to a material delivery mechanism and the port connector being configured to attach to the medical implant. When the material delivery mechanism is actuated, the flowable material passes through the tube to the medical implant. A method of using an injector assembly to deliver a flowable material to a medical implant and bone surface is also described.
