description A deflection apparatus is provided. In one described embodiment, the apparatus includes a torque resistant retrievable whipstock sealingly attached to a packer. The whipstock may be separated from the packer by applying an axial force to a first housing and thereby releasing a sleeve sealingly disposed between the first housing and a second housing for displacement relative to the second housing. The first housing and sleeve may then be removed from within the second housing, leaving a relatively large diameter seal bore attached above the packer.
