Abstract
Apparatuses and methods used for actuating downhole tools in which a ball is dropped from a surface of a wellbore until it contacts a ball seat of a downhole tool. The ball seat moves axially downward within the downhole tool and an expandable ball seating surface of the ball seat radially expands to pass the ball. The ball seat then moves axially upward within the downhole tool.
