SURGICAL SEAL WITH VARIABLE DIAMETER
First Claim
1. A surgical access assembly, which comprises:
- an access member dimensioned for positioning with a patient'"'"'s tissue and defining a passageway extending longitudinally therethrough configured to removably receive a surgical object;
a seal member including an internal channel defined therein and having an aperture extending therethrough, the seal member being selectively adaptable to transition between a first condition wherein the aperture includes a first diameter and a second condition wherein the aperture includes a second diameter that is smaller than the first diameter; and
at least one closure member at least partially disposed within the internal channel which is actuatable to transition the diameter of the seal member from the first condition to the second condition upon actuation thereof.

Abstract
A surgical access assembly dimensioned for positioning within a patient'"'"'s tissue includes a seal member having an internal channel defined therein for the reception of a closure member, and an aperture extending through the seal member that is configured to removably receive a surgical object upon its insertion into the surgical access assembly. The closure member is selectively actuable to transition the seal member from a first condition, in which the aperture includes a first diameter, to a second condition, in which the aperture includes a second diameter. The second diameter is less than the first diameter and substantially approximates an outer dimension of the surgical object such that a substantially fluid-tight seal is formed therewith.
