A surgical access assembly is disclosed. The surgical access assembly comprises an outer sheath defined by an open distal end and an open proximal end and including a hollow body portion therebetween; an obturator defined by a distal end and a proximal end, a body portion therebetween, and has a central channel formed within the body portion, wherein the distal end further comprises a tapered distal tip member that terminates in a closed radiused distal tip; a navigational probe, wherein the navigational probe is selectively seated within the central channel; andwherein the obturator is configured to be received within the outer sheath such that the tapered distal tip member protrudes from the open distal end of the outer sheath when the obturator is in an introducing configuration. |
