Zusammenfassung: | An esophageal stent configured to span a stricture may include a tubular body configured to shift between a delivery configuration and a deployed configuration, the tubular body having a first end and a second end. In the deployed configuration: the tubular body defines a first flange portion, a second flange portion, and a saddle portion extending from the first flange portion to the second flange portion; the tubular body further defining an overall longitudinal length extending from the first end to the second end; the first flange portion has a first outer radial extent, and the second flange portion has a second outer radial extent; the first outer radial extent and the second outer radial extent are greater than an outer radial extent of the saddle portion; and a longitudinal length of the saddle portion is at least 50% of the overall longitudinal length of the tubular body. |
