Claim 7:
8. A plug configured to isolate formation zones within a wellbore, the plug comprising:
a flow control subassembly configured to control the flow of fluid through the plug, the flow control subassembly comprising:
a central chamber;
a ball; and
an offset chamber connected to the central chamber, wherein the offset chamber includes a ball release mechanism that is configured to selectively release the ball from the offset chamber into the central chamber, wherein the ball release mechanism is configured to rupture in response to a force applied to the ball that exceeds a threshold rupture force of the ball release mechanism, and wherein the threshold rupture force is produced in part by a suction force acting on an interior side of the ball, where the suction force is generated by the movement of fluid through the central chamber;

an anchoring subassembly configured to secure the plug in the wellbore; and
a sealing device between the flow control subassembly and the anchoring subassembly.
