Abstract
A device such as a smart dart is configured to reversibly engage and disengage with a seat in a tubing string. In an engaged configuration, pressure applied above the device forces a first seat component to engage a second seat component. The interaction of the first seat component and the second seat component under pressure produces an inwardly radial circumferential force that grips the device within the seat and may also form a seal between the device and the seat.
