<P>PROBLEM TO BE SOLVED: To provide a surgical valve adapted to limit any undesirable motions of a surgical object by forming a substantially fluid-tight seal vis-a-vis the surgical object. Ž<P>SOLUTION: A surgical access instrument 10 for use during the course of a minimally invasive surgical procedure, includes an access member defining a longitudinal axis and having a longitudinal opening for reception and passage of a surgical object, a valve membrane 100 mounted to the access member, including a biocompatible material, defining at least one internal cavity and permitting passage of the surgical object and a dynamic fluid disposed within the internal cavity. The dynamic fluid is adapted to transition from a first state to a second state upon exposure thereof to a stimulus to assist in stabilizing the surgical object relative to the access member.
