Abstract: A status indicator for determining a position of an extendable member in an expandable apparatus. The status indicator is configured to decrease a cross-sectional area of a portion of a fluid path extending through an expandable causing a pressure of a fluid within the fluid path to increase when an extendable member of the expandable apparatus is in an extended position. By determining the pressure of the fluid within the fluid path, one can determine the position of the status indicator within the fluid path and thereby determine whether the extendable member of the expandable apparatus is in the extended or a retracted position.
