Abstract
A dual-flange stent can have a therapeutic effect that can bring about a marked increase in patency. The dual flanges of the stent can comprise a first discrete flange component and a second discrete flange component. One or both flange components can include a magnetic element. The stent can further comprise a shaft connecting the flange components. At least one of the flanges can transition between a first configuration and a second configuration, where the first configuration is compact and the second configuration provides a large tissue-compressing surface. In one instance, the transition to the configuration with a large tissue-compressing surface can include filling a balloon with saline or another fluid. The first flange and the second flange may be drawn together to compress interposed tissue of the stricture.
