Patent ID: 8281818

Claim:
A device, comprising: a shaft assembly having first and second ends, and defining a hollow interior pathway between the first and second ends; a plug assembly disposed adjacent the first end of the shaft assembly and comprising a laterally expandable member configured to expand laterally about a longitudinal axis of the shaft assembly when compressed longitudinally; a longitudinal expansion assembly disposed adjacent the second end of the shaft assembly and configured to expand longitudinally; a longitudinal coupling member disposed between the longitudinal assembly and the plug assembly such that when the longitudinal expansion assembly expands, longitudinal coupling member transfers a longitudinal force due to expansion to the plug assembly to provide the longitudinal compression for the laterally expandable member; and a removable cap member disposed on the second end of the shaft assembly, the cap member including an aperture to allow passage of fluid or gas from or to the hollow interior pathway of the shaft assembly, wherein the shaft assembly is configured to allow attachment of an end device to the longitudinal expansion assembly over the cap member, the cap member configured to engage the end device when the end device is attached to the longitudinal expansion assembly.
