Abstract
A downhole tool includes an expandable sleeve. The expandable sleeve includes a lower portion and an upper portion. The downhole tool also includes a lower cone positioned at least partially within the lower portion of the expandable sleeve. The downhole tool also includes an upper cone positioned at least partially within the upper portion of the expandable sleeve. The lower and upper cones are configured to expand the respective lower and upper portions of the expandable sleeve radially outward when the lower and upper cones are adducted toward one another. The downhole tool also includes an isolation device extending through the bore of the expandable sleeve and positioned radially inward of the lower and upper cones. The isolation device is configured to engage the upper cone so as to block fluid flow therethrough in at least one direction.
