PROBLEM TO BE SOLVED: To provide a surgical access port including a securing member configured for securing the surgical access port relative to tissue. SOLUTION: A surgical access port apparatus includes: a portal member including an outer wall defining a longitudinal axis and having a proximal end, a distal end, and a lumen configured to allow a surgical instrument to pass therethrough; and a securing member operatively connected to the distal end of the outer wall of portal member. The securing member is movable with respect to the portal member between an initial at least partially coiled condition defining a first transverse dimension and an activated condition defining a second transverse dimension greater than the first transverse dimension to engage body tissue to assist in retaining the portal member within the body tissue.
