First Claim
Patent Images
1. An obturator, comprisinga solid rod having a distal end, a proximal end, a longitudinal axis and an outer surface;
- a groove extending partially into the rod through the outer surface, said groove substantially parallel to the longitudinal axis, said groove having a proximal end, a distal end proximal to the distal end of the rod, a closed bottom, opposed sides, a width between the sides and an open top having a width, wherein the width of the opening of the top is greater than or equal to the width between the sides; and
, a piercing point extending distally from the distal end of the rod, wherein an elongated instrument contained within the groove is displaceable radially outward from the groove.
