Abstract
A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either device within the brain.

1-15. (canceled)
A surgical access assembly for creating an operative pathway through body tissue, comprising:
- 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, wherein the distal end further comprises a tapered distal tip member that terminates in a closed distal tip for atraumatically dilating tissue and the proximal end comprises a grip member and a stop member, wherein the stop member engages the proximal end of the outer sheath when the obturator is received within the outer sheath when in an introducing configuration;
- and
- a navigational element operatively connected to one of the obturator and outer sheath, wherein the navigational element is configured to indicate the location of at least a portion of the surgical access assembly within a patient during use;
- wherein the tapered distal tip member protrudes from the open distal end of the outer sheath when the obturator and outer sheath are assembled in the introducing configuration, forming an atraumatic assembly distal end.
