Claim Text:
1. A lumen support configured to be expanded and contracted to a plurality of stable positions, the support comprising a plurality of cells, each of the plurality of cells defined by at least a first segment and a second segment, the cell comprising a first stable collapsed configuration, a second stable collapsed configuration, a first stable expanded configuration, and a second stable expanded configuration, the first segment, comprising a material having an elastic range between about 0.15 to about 1% and an elongation of above 30% and an ultimate tensile strength greater than 500 MPa, the material exhibiting reduced recoil to an applied force, and the second segment being less flexible than the first segment, said first segment of each cell being configured to transition from a first stable collapsed configuration to a first stable expanded configuration relative to said second segment thereby causing each cell to transition from the first stable collapsed configuration to the first stable expanded configuration, wherein said first segment is configured to plastically deform to a second stable collapsed configuration creating an area for each cell less than the area created when said first segment is at said first stable collapsed configuration, and wherein said first segment is configured to plastically deform to a second stable expanded configuration creating an area for each cell greater than the area created when said first segment is at said first stable expanded configuration.
