Paragraph Number

154

The third section 922 connects to and extends from the second section 920, just as the second section 920 connects to and extends from the first section 918. In one embodiment, the third section 922 includes a second diameter that is smaller than the first diameter. In certain embodiments, the planar surface(s) 924 can extend into the third section 922. The extending planar surfaces 924 can form one or more lips 928 between the second section 920 and the third section 922. These one or more lips 928 may serve to restrict movement of a puller 1004 towards the distal end 906 of the shaft 902 past the one or more lips 928. In one embodiment, the puller 1004 is connected to the shaft 902 near a proximal end 904 of the shaft 902.
