Abstract
A downhole tool includes a body defining an axial bore and one or more radial ports. The downhole tool also includes a first sleeve positioned at least partially within the body. The first sleeve is configured to block fluid communication from the axial bore through the one or more radial ports when the downhole tool is in a first position. Fluid flow is permitted from the axial bore through the one or more radial ports when the downhole tool is in a second position. The downhole tool also includes a second sleeve positioned at least partially within the body. The second sleeve is configured to block fluid communication from the axial bore through the one or more radial ports when the downhole tool is in a third position. The downhole tool also includes a seat coupled to the second sleeve. The seat is configured to receive an impediment.
