364 and respective gaps 368 is a centered gap 384 that also tapers distally to create a through hole 386 having a rectangular rounded cross section that extends into the interior of the distal aspect 370 of the dual pivot joint the tapered feature of this centered gap 384 is partially defined by a pair of angled faces 388 that operate to allow the draw wire 228 and clip release wires 292 to be fed in between the walls 364 through the hole 386 and into the interior of the distal aspect where the wires are ultimately fed through a clip deployment frame 520 the tapered nature of this gap 384 ensures that the draw wire 228 and clip release wires 292 do not become bound up by pivoting action of the dual pivot joint 350 with respect to the clevis 302 but for the tapered nature of the gap 384 pivoting action beyond center of the dual pivot joint 350 with respect to the clevis 302 would cause the path of the draw wire 228 and clip release wires 292 to be lengthened thereby potentially resulting in premature release of the clip 1160 and opening of the clip adjoining the angled faces 388 is an arcuate wall 390 that curves around a lateral edge of the proximal section 352 and extends into the interior of the distal section 370 the arcuate wall 390 is inset within the proximal section 352 to create a lateral.
