Abstract
A downhole tool, tool assembly, and method, of which the downhole tool includes an expandable sleeve defining a bore extending axially therethrough, and including a shoulder that extends inward from the bore, 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, a second swage positioned at least partially within the bore. The first and second swages are configured to deform the expandable sleeve radially outwards when the first and second swages are moved toward one another within the expandable sleeve, and the shoulder is configured to prevent at least one of the first and second swages from sliding therepast.
