Patent attributes
Aspects of the invention include a nozzle assembly having a housing configured for attachment to the wall of the vessel. The housing has a proximal end portion and a distal end portion spaced from the proximal end portion along a length of the housing. The housing defines a passageway extending from the proximal end portion to the distal end portion, which is delineated by an inner surface of the housing. The nozzle assembly further includes a nozzle that has a base portion adapted for coupling to the housing, a shaft portion that extends from the base portion, and a tip portion coupled to the shaft portion of the nozzle. The tip portion defines a plurality of orifices. The nozzle also has an outer surface extending along a length of the nozzle that is spaced from the inner surface of the housing to create a gap when the nozzle is coupled to the housing.
