The present invention provides a bi-directional ball seat and method of use. In at least one embodiment, the present invention provides a fluid control system that includes a radial protrusion that can be selectively engaged and disengaged upstream and/or from a ball seat. For example, a ball can be placed in a passageway, engaged with a downstream ball seat, and the radial protrusion radially extended into the passageway distally from the seat relative to the ball. A reverse movement of the ball is restricted by the active radial movement of the radial protrusion into the passageway. The control system can be used to control a variety of tools associated with the well. Without limitation, the tools can include crossover tools, sleeves, packers, safety valves, separators, gravel packers, perforating guns, decoupling tools, valves, and other tools know to those with ordinary skills in the art.

What is claimed is: 1. A method of using a fluid control system for a hydrocarbon well, the control system comprising a first portion having at least one actuator, an inner sleeve slidably disposed with the first portion and forming a longitudinal passageway, and at least two radial protrusions disposed at least partially in the inner sleeve and exposed to the passageway, the at least two radial protrusions being adapted to selectively extend into and retract from the passageway, the method comprising: using the control system with the at least two radial protrusions extended into the passageway and with a movable restriction disposed in the passageway and restricted in longitudinal travel between the at least two extended radial protrusions; and moving the inner sleeve relative to the first portion so that at least one of the at least two radial protrusions retracts from the passageway to selectively release the movable restriction from between the at least two radial protrusions. 2. The method of claim 1, further comprising pressurizing a volume of the passageway adjacent the movable restriction to cause the inner sleeve to move relative to the first portion of the control system. 3. The method of claim 1, wherein the at least one of the at least two radial protrusions is locked radially toward the passageway when actuated. 4. The method of claim 1, further comprising at least one tool associated with a hydrocarbon well that is coupled to the control system. 5. The method of claim 1, wherein the at least two radial protrusions are each adapted to retract from the passageway. 6. The method of claim 1, wherein the control system comprises a cartridge disposed within a tubular string. 7. The method of claim 1, wherein the control system comprises a modular unit coupled to other tools in a tubular string. 8. The method of claim 1, wherein the control system is flow rate sensitive. 9. The method of claim 1, wherein the control system comprises a multi-staged actuation. 10. The method of claim 1, wherein the control system further comprises a passageway seal disposed between the at least two radial protrusions, and further comprising selectively restricting flow through the passageway by sealing the movable restriction with the passageway seal when the movable restriction is engaged with at least one of the at least two radial protrusions. 11. The method of claim 10, wherein the movable restriction is in contact with the passageway seal when the movable restriction is in contact with at least one of the at least two radial protrusions to form a flow restriction in the passageway. 12. The method of claim 10, wherein the passageway seal comprises a first and second portion, and wherein at least one of the seal portions and at least one of the at least two radial protrusions is adapted to concurrently engage the movable restriction. 13. The method of claim 1, wherein the movable restriction comprises a covering over a disintegratable core. 14. The method of claim 13, wherein at least one of the at least two radial protrusions comprises at least one cutter and the movable restriction comprises a covering disposed over a disintegratable core and further comprising impairing the covering with the cutter to expose at least a portion of the core.
