1. A nozzle assembly comprising:
a hollow body having a generally cylindrical exterior surface and defining a longitudinal axis;
a domed outer surface;
a retaining lip extending radially from the domed outer surface; and
a port configured to couple to a catheter;
wherein the hollow body defines a plurality of orifices extending through the domed outer surface, each orifice able to form a fluid connection between an interior volume within the hollow body and an exterior volume outside the nozzle assembly, one or more of the plurality of orifices configured to deliver liquid received from the port to the exterior volume in a direction forming an angle of between 5° and 85° with respect to a direction of the longitudinal axis of the hollow body, the one or more of the plurality of orifices defined by a first hole in an inner surface of the hollow body proximate the interior volume and a second hole in an outer surface of the hollow body proximate the exterior volume, wherein the first hole has a first cross-sectional shape and the second hole has a second different cross-sectional shape larger than the first cross-sectional shape.
