Abstract
A surgical access assembly is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath is defined by an open distal end and an open proximal end and includes a hollow body portion therebetween. The obturator is defined by a distal end and a proximal end and the distal end further comprises a tapered distal tip member that terminates in a closed radiused distal tip. 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.
