Abstract
There is provided an expandable tube for deployment within a blood vessel, the expandable tube being reversibly switchable from a radially contracted and longitudinally expanded state to a radially expanded and longitudinally contracted state, the expandable tube comprising a first frame comprising braided filament, and a second frame connected to the first frame and overlapping with the first frame in the radial direction, the second frame comprising a network of non-overlapping elements, the non-overlapping elements being non-overlapping with respect to each other in the radial direction, wherein the network of non-overlapping elements has an interconnected structure comprising a plurality of sub-units that repeat in the longitudinal direction.
