Patent number: 9289233Abstract: A surgical access device includes a proximal housing having proximal and distal end portions, the distal end portion of the housing being configured and adapted to engage a proximal portion of a flexible wound retractor. The proximal housing can be provided with a plenum chamber being defined therein, the plenum chamber being in fluid communication with at least one nozzle. The nozzle is preferably configured to direct pressurized fluid in an axial direction from the plenum chamber into a central bore of the surgical access device to provide a constant gaseous seal around a surgical instrument inserted therethrough, while inhibiting a loss of pressurized fluid from the body cavity therethrough. The plenum chamber can be adapted and configured to receive pressurized fluid and conduct the pressurized fluid to the at least one nozzle.Type: GrantFiled: October 11, 2009Date of Patent: March 22, 2016Assignee: SurgiQuest, Inc.Inventors: Ralph Stearns, Kurt Azarbarzin, James R.

Patent number: 9155557Abstract: An access device adapted and configured to be inserted through a natural biological orifice, and related surgical methods are provided. The access device includes a body, a nozzle means and means for delivering a pressurized flow of fluid to the nozzle means. The body is configured and dimensioned to be inserted through a natural bodily orifice and has proximal and distal end portions and defines at least one lumen therethrough to accommodate passage of one or more surgical instruments. The nozzle means is operatively associated with the body for directing pressurized fluid into the lumen to develop a pressure differential in an area within a region within the lumen to form a fluid seal around the one or more surgical instruments passing therethrough.Type: GrantFiled: April 17, 2008Date of Patent: October 13, 2015Assignee: SurgiQuest, Inc.Inventors: Kurt Azarbarzin, Daniel B.

Patent number: 9095372Abstract: Systems for insufflation and recirculation of insufflation fluid in a surgical procedure include a control unit having a fluid pump, a supply conduit, a return fluid conduit and a pressure-controlled valve. The pressure-controlled valve is in fluid communication with an insufflation gas supply, the supply conduit and the return conduit and is adapted and configured to respond to pressure control signals to adjust position and thereby system flow parameters, to reduce entrainment of air from the surrounding environment, and to increase the concentration of insufflation gas in an operative space, and/or to reduce an overpressure condition in the operative space.Type: GrantFiled: June 6, 2014Date of Patent: August 4, 2015Assignee: SurgiQuest, Inc.Inventors: Ralph Stearns, Kurt Azarbarzin, Timothy J.
