Zusammenfassung:	A packer (10) for use in a well bore has a housing assembly (22) with an operating mandrel assembly (32) disposed therein. A packer mandrel assembly (24) is slidably connected to the housing assembly (22). During operation, the operating mandrel assembly may be actuated to cycle a tool below the packer without setting the packer. After the operating mandrel assembly and housing assembly are moved a predetermined amount with respect to the packer mandrel assembly, the housing assembly is brought into contact with a sliding shoe (172) on the packer mandrel assembly which in turn engages and deforms packer elements (26) into sealing engagement with the well bore.
