1. A gaseous sealing module for use with a surgical gas delivery device comprising:
a) a vented housing defining an interior plenum chamber and having a tapered throat portion that extends from a distal end of the vented housing for communication with a gas sealed lumen, wherein the vented housing is located remote from the surgical gas delivery device and includes a louvered vent surface formed in an exterior proximal end wall of the vented housing opposite the tapered throat portion;
b) a ring jet assembly disposed within the interior plenum chamber of the vented housing between the tapered throat portion and the exterior proximal end wall for generating a gaseous seal within an interior region of the tapered throat portion of the vented housing, which creates a stable pressure barrier that maintains a stable pressure through a length of the gas sealed lumen, wherein an unfiltered vent path extends from the tapered throat portion, through the ring jet assembly, to the louvered vent surface; and
c) a connective fitting extending from the vented housing and defining a gas delivery path in communication with the interior plenum chamber of the vented housing and a gas return path in communication with the tapered throat portion of the vented housing, wherein the gas delivery path of the connective fitting is configured to connect with a gas delivery lumen of a filtered tube set and the gas return path of the connective fitting is configured to connect with a gas return lumen of the filtered tube set.
