Abstract
An inflatable bladder includes, but is not limited to, a bladder body having a wall, a longitudinal dimension, and a lateral dimension. The wall defines an interior volume enclosing a fluid. The wall further defines an opening in fluid communication with the interior volume. The bladder body is fluid tight when the opening is closed. The wall is configured to facilitate an expansion of the longitudinal dimension during an ingress of the fluid into the interior volume and a contraction of the longitudinal dimension during an egress of the fluid from the interior volume. The wall is further configured to maintain a constant lateral dimension during the ingress of the fluid into the interior volume and a constant lateral dimension during the egress of the fluid from the interior volume.
