Abstract:
1. A surgical portal apparatus, which comprises: a portal member defining a longitudinal axis and having leading and trailing ends, the portal member including an outer wall defining a longitudinal opening dimensioned for reception and passage of a surgical object; and at least one projection mounted adjacent the outer wall of the portal member and extending radially outwardly from the outer wall, the at least one projection having an internal recess forming an enclosed pocket defined within a peripheral boundary of the at least one projection and the outer wall of the portal member and having an opening in communication with the internal recess, and being dimensioned for receiving tissue portions adjacent thereto, wherein the peripheral boundary of each of the at least one anchoring projection is defined by at least two substantially planar distal leading surfaces and at least two substantially planar proximal trailing surfaces, the leading and trailing surfaces extending distally and converging at a line of intersection that is remote the outer wall of the portal member, the leading surfaces also converging at an apex that is proximate the outer wall of the portal member such that the pocket is of diminishing tissue passing capacity as the pocket extends from the line of intersection to the apex.
