Abstract
A system for performing an endoscopic surgical procedure in a surgical cavity of a patient that includes a gas delivery device configured to deliver a flow of pressurized gas to a gas delivery lumen extending therefrom, a gaseous sealing module communicating with a distal end of the gas delivery lumen and configured to generate a gaseous seal within a gas sealed lumen extending therefrom, and an access port communicating with a distal end of the gas sealed lumen so as to provide sealed instrument access to the surgical cavity and maintain a stable pressure within the surgical cavity.

A filtered tube set for use with a gas delivery device for performing an endoscopic surgical procedure in a surgical cavity, comprising:
- a) a filter cartridge assembly having first and second flow paths formed therein;
- b) a first lumen extending from the filter cartridge and communicating with the first flow path for communicating with the surgical cavity to maintain a stable pressure level and facilitate smoke evacuation therein;
- and
- c) a second lumen extending from the filter cartridge and communicating with the second flow path to deliver insufflation gas to the surgical cavity and to sense cavity pressure.
