Abstract
A tubular actuator includes, a tubular, a support member disposed at the tubular, and a restrictor configured to pass a runnable member when unsupported by the support member and to prevent passage of the runnable member when supported by the support member. The restrictor is movable relative to the support member from an unsupported position to a supported position in response to pressure applied against the runnable member engaged with the restrictor according to a pressure versus time profile.
