Abstract:
A stretchable stent, comprising:a coiled-up sheet having overlapping inner and outer longitudinal sections, and being radially expandable between a first size and one or more larger sizes, the coiled-up sheet defining a periphery in a plane substantially perpendicular to a longitudinal axis thereof; a plurality of engagement elements on the inner longitudinal section for engaging openings in the outer longitudinal section to selectively secure the coiled-up sheet in the one or more larger sizes; and a stretchable portion comprising a plurality of resilient mesh elements extending along a portion of the coiled-up sheet, the mesh elements being biased to a stretched configuration assuming an enlarged size about the periphery of the coiled-up sheet, the mesh elements being compressible to an unstretched configuration defining a smaller size about the periphery of the coiled-up sheet than the stretched configuration.
