Abstract
A ball catching device has been invented that catches an actuator ball used in a wellbore to actuate a downhole tool. The device catches the ball downhole as it begins to flow back with fluids toward surface. The device is configured such that when a ball flows back with wellbore fluids, the ball can flow through the device and if the ball reverses direction, as by falling back due to decreased or stopped production back flow, then the device will catch the ball and keep it from falling back past the device into the well.
