Abstract: A downhole tool and a tool assembly, of which the downhole tool includes an expandable sleeve defining a bore extending axially therethrough, a first swage positioned at least partially within the bore and including a valve seat configured to receive an obstructing member, such that the obstructing member and the first swage substantially prevent fluid communication through the bore when the obstructing member is seated in the valve seat, and a second swage positioned at least partially within the bore. The first and second swages are configured to move toward one another in the bore, such that the first and second swages deform end portions of the expandable sleeve radially outwards and into engagement with a surrounding tubular, and the expandable sleeve, in an expanded configuration in which the end portions engage the surrounding tubular, defines an unexpanded portion between the expanded end portions.
