A packer assembly for use within a wellbore. The packer assembly may include a mandrel, a seal assembly disposed about the mandrel, an anti-extrusion assembly disposed about the mandrel proximate the seal assembly to prevent extrusion of the seal assembly, and a deployment system. The anti-extrusion assembly may include a cradle cone that may include a plurality of arcuate surfaces on an exterior of the cradle cone and a plurality of cradle arms. Each cradle arm may include a flexible tip and be positioned on a respective arcuate surface of the cradle cone. The deployment system may be operable to compress the seal assembly such that the seal assembly seals against a wellbore wall and to rotate the plurality of cradle arms such that the flexible tips of the cradle arms contact the wellbore wall to prevent extrusion of the seal assembly.

A system and method for providing a rotating a mule shoe assembly. The mule shoe assembly is disclosed with a top sub adapted to be connected to a tool string. A spring retainer for retaining a wave spring in a chamber created by the top sub and spring retainer. A mule shoe adjacent the spring retainer that linearly translate and rotate when a force is applied. The spring retainer has one or more pins that engages one or more linear slots in the top sub. A key moves in an indexing slot causing the mule shoe to linearly translate and rotate. The indexing slot is machined in the outer diameter of the top sub. During the stroke of the mule shoe, the one or more pins move in the linear slots and the key moves in the indexing slot.
