Abstract:
1. A device for placement in a lumen, the device comprising: a plurality of segments, wherein each segment comprises a first helical coil and a second helical coil of opposing winding sense and each segment is connected to another segment by a first structure, wherein each first structure changes the winding sense of adjacent segments, wherein each first structure comprises a cross-over point comprising an end of one of the first helical coils overlapping an end of one of the second helical coils, wherein the end of the first helical coil and the end of the second helical coil are joined, and each first structure extends into and fills a gap created by the divergence of the segments connected to each first structure, and wherein each first structure pushes the end of the first helical coil and the end of the second helical coil against a wall of the lumen and exerts force on the lumen.
