Abstract
A subsurface tool adapted to extend within a wellbore that includes an outer sleeve defining a first passageway; an inner sleeve disposed within the first passageway to form an annulus between the outer sleeve and inner sleeve; and a first annular diaphragm extending between the outer sleeve and the inner sleeve to fluidically isolate a first portion of the annulus from and a second portion of the annulus; wherein when the tool is in a first configuration, the first annular diaphragm is integrally formed with the inner sleeve and outer sleeve to form a single-component tool.
