Abstract: An irrigation device for injecting a fluid into a channel formed in an object relative to a surface of the object for washing walls defining the channel. The walls intersect to form at least one terminal portion disposed distal to the surface. The irrigation device includes an elongate body extending between an inward end and an outward end. The body includes a nozzle positioned at the inward end, and an input duct extending between the outward end and the inward end and in fluid communication with the nozzle for directing the fluid to the nozzle. The nozzle includes a plurality of output ducts in fluid communication with the input duct. The output ducts are positioned to direct the fluid out of the body substantially toward the walls and substantially toward the surface upon positioning the nozzle proximal to the terminal portion of the channel.
