Claim:
1. A surgical obturator, comprising: an elongate shaft extending along a longitudinal axis between a proximal end and a distal end; and a bladeless tip disposed at the distal end of the shaft having a conical surface forming proximally into an outer surface and distally to a blunt surface, said outer surface extending distally to the conical surface and having a pair of opposing surfaces separated by a pair of side surfaces; wherein the conical surface extends proximally from the blunt surface and is formed into the pair of opposing surfaces such that a portion of the conical surface formed in the opposing surfaces defines an intersection that is generally U-shaped; wherein the side surfaces define short sides of a rectangle and the opposing surfaces define long sides of the rectangle in a cross-section taken perpendicular to the longitudinal axis and along the outer surface; and wherein the side surfaces increase in length with consecutive proximal cross-sections taken perpendicular to the longitudinal axis.
