ABSTRACT:
A surgical portal apparatus for permitting introduction of a surgical object within tissue includes a portal member defining a longitudinal axis and having leading and trailing ends. The portal member includes an outer wall defining a longitudinal opening dimensioned for reception of a surgical object. At least one projection is disposed on the outer wall of the portal member and extends in at least a radial direction relative to the longitudinal axis. The at least one projection is dimensioned and configured for engaging tissue to resist movement of the portal member within tissue. The at least one projection defines a recess for receiving tissue portions adjacent thereto. A plurality of projections is spaced about the outer wall of the portal member. At least two of the projections are circumferentially spaced relative to the longitudinal axis and/or at least two of the projections are longitudinally spaced relative to the longitudinal axis.
