Abstract
Downhole tools and methods, of which the downhole tool includes an expandable sleeve defining a bore therethrough, and a first body positioned at least partially within the bore of the expandable sleeve. The first body is slidable relative to the expandable sleeve, and sliding the first body along the bore of the expandable sleeve causes the expandable sleeve to radially expand so as to actuate the downhole tool from a run-in configuration to a set configuration. The downhole tool also includes an isolation device received at least partially in the expandable sleeve in the set configuration. A pressure on the isolation device is at least partially transmitted to the expandable sleeve as a radially-outward force.
