Abstract
A surgical access assembly includes a cannula including an elongated shaft and a retention anchor movable position along the elongated shaft. The retention anchor includes an annular body and a wiper disposed at a distal end of the annular body. The annular body includes a proximally-facing surface, a distally-facing surface, an outer side surface, and an inner side surface. The inner side surface defines a channel for reception and passage of the elongated shaft therethrough and the proximally-facing surface defines a proximal opening into the channel. The wiper extends radially inwardly of the inner side surface and defines a distal opening into the channel for establishing a sealed relation about the elongated shaft. The distal opening has a smaller diameter than the proximal opening.
