Zusammenfassung:The present invention relates generally to the field of medical devices. In particular, the present invention relates to medical devices for facilitating flow of fluids and materials in and/or between adjacent body cavities, e.g., a stent that maintains an open flow path between body cavities. In one example, the stent may have a restricted configuration and an expanded configuration. In the expanded configuration, the stent may have first and second retention members and a saddle region extending therebetween. The saddle region may include a coil configured to apply a restoring force to a tissue surface juxtaposed with the first and second retention members, respectively. 本发明总体涉及医疗装置领域。特别地,本发明涉及用于促进流体和材料在相邻体腔中和/或之间流动的医疗装置,例如,一种在体腔之间保持开放的流动通路的支架。在一个示例中,支架可具有受限形态和扩张形态。在扩张形态中,支架可具有第一和第二保持构件和在其之间延伸的鞍状区域。鞍状区域可包括线圈,其配置为向分别与第一和第二保持构件并置的组织表面施加恢复力。
