A spinous process spacer that is designed to maintain a desired spatial relationship between adjacent vertebrae, is configured for introduction into a spinal implant site in a compressed state and then expands in situ. Once expanded, formations of the present spinal spacer form areas, pockets or spaces that receive at least one bony portion of each adjacent vertebra. The present spinous process spacer has a changeable circumferential profile wherein a first circumferential profile is smaller than a second circumferential profile in order to provide / achieve its compressed and expanded states. The first circumferential profile defines the collapsed position or state while the second circumferential profile defines the position or state. Upon implantation, the present spinous process spacer is not fixed to any bony structure of the vertebrae but provides support. In this regard, use of the spinous process spacer, by itself, will not result in vertebral fusion. However, fusion can result with the use of bone graft packed about the spinous processes (and the spinous process spacer) or in conjunction with the use of an intervertebral body spacer.

A tire includes at least one carcass-type reinforcement structure anchored on each side in a bead, each bead being extended radially towards the outside by a sidewall having at least one substantially resilient circumferential cord disposed in the substantially median portion of the sidewalls. The carcass-type reinforcement structure includes a ply of carcass cords extending from the bead to the crown within a sidewall. The carcass cords are arranged in such a way that, in a sidewall zone restricted to the median portion of the sidewall, the carcass cords exhibit different respective axial positions, so as to form around the circumference a succession of substantially regular undulations defining an undulating circumferential profile. Outside of the sidewall zone, the carcass cords of the ply do not form undulations. At reduced pressure the undulations tend to straighten out and rigidify the sidewall in such a way as to be able to bear the load.
