Abstract
Official abstract text for this publication.
A surgical obturator that includes an elongated shaft defining a longitudinal axis and an obturator member disposed adjacent a distal end of the elongated shaft. The obturator member may include a proximal section being convex along a majority of its length. It may also include a central section disposed adjacent the proximal section, the central section including a first pair of surfaces disposed relative to each other on radially opposite sides of the central section, and a second set of surfaces disposed between the first pair of surfaces and further being disposed relative to each other on radially opposite sides of the central section, at least a portion of a length of each one of the first pair of surfaces being concave, and at least a portion of a length of each one of the second pair of surfaces being convex. The obturator member may also include a guiding nub disposed distally of the central section and including a rounded distal-most portion. The rounded distal-most portion of the guiding nub may be atraumatic to tissue.
