  • Patent number: 11534539
    Abstract: An evacuation system and method for removing and/or treating gaseous and/or particulate byproducts of surgical procedures includes an end effector such as a side vent trocar, an operating room tower or the equivalent, a disposal vessel, a vacuum source and optionally a filter. The end effector may be coupled to the tower by a conduit, the tower may be coupled to the collection tank by a conduit, and the collection tank may be coupled to the vacuum source. Gaseous and/or particulate byproducts may flow from the surgical site through the trocar, conduits, tower tank and filter, and the flow may be regulated at least in part by the components of the system.

  • Patent number: 8708985
    Abstract: An apparatus for evacuating material from a surgical site, the apparatus including a housing and a filter media, and being operably coupled to a vacuum source. The housing includes a top surface, a bottom surface and an outer side wall, together defining an inner cavity of the housing. The housing further includes an access opening in fluid communication with the inner cavity and one or more ingress apertures in fluid communication with the access opening. The filter media is positioned in or adjacent to the inner cavity such that a flow of fluid through the ingress apertures is moved through the filter media.

  • Patent number: 7959698
    Abstract: A smoke evacuating system for use during surgical procedures, particularly minimally invasive procedures involving the use of a laser or cautery at a surgical site having an associated higher than ambient pressure, wherein the system includes a filter with a site side and an outlet side and a fluid conduit extending between the surgical site and the filter. The filter includes a filter media and a housing substantially surrounding the filter media with a space between the filter media and the housing to collect condensed vapor. The filter exhibits low resistance or a low pressure drop and resists fluid flow, whereby the higher than ambient pressure is not substantially diminished and generates a fluid flow in the fluid flow path tending to carry smoke to and through the filter.
