Surgical gas delivery device with internal gaseous sealing module and filtered tube set therefor

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.

1 - 14 . (canceled) 
     
     
         15 . 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.   
     
     
         16 . A filtered tube set as recited in  claim 15 , wherein a fitting is operatively associated with a distal end of the first lumen for connection with a first valve sealed access port. 
     
     
         17 . A filtered tube set as recited in  claim 15 , wherein a fitting is operatively associated with a distal end of the second lumen for connection with a second valve sealed access port. 
     
     
         18 . A filtered tube set as recited in  claim 15 , wherein at least one filter element is disposed within the first filtered flow path of the filter cartridge. 
     
     
         19 . A filtered tube set as recited in  claim 15 , wherein at least one filter element is disposed within the second filtered flow path of the filter cartridge. 
     
     
         20 . A filtered tube set as recited in  claim 15 , wherein the first lumen is configured for bi-directional gas flow so as to facilitate stable pressure in the surgical cavity and facilitate smoke evacuation from the surgical cavity.
