Abstract
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.

26. An access device adapted and configured to be inserted into a natural lumen of a patient'"'"'s body through a natural orifice to gain access to a surgical site in a body cavity through a wall of the natural lumen, the access device comprising:
-
a) a proximal housing portion; b) an elongated flexible body portion extending distally from the proximal housing portion, the flexible body portion dimensioned and configured for transluminal access to the surgical site and having a tubular wall defining a central lumen to accommodate the passage of surgical instruments to the surgical site; and c) a nozzle formed within the proximal housing portion for directing pressurized fluid into the central lumen of the flexible body portion to develop a pressure differential between the pressure at the surgical site and the pressure outside of the surgical site, the pressure differential forming a barrier to the egress of pressurized fluid from the surgical site through the central lumen of the flexible body portion, while forming a fluid seal around surgical instruments passing through the central lumen of the flexible body portion to the surgical site - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35)
