Abstract
A stent device and methods for inserting and removing a stent to and from an anatomical tract of a living being. The stent includes a distal segment and a proximal segment joined by a flexible connection structure. The stent is inserted using components comprising a delivery assembly such that the stent proceeds through the anatomical tract and seats the flexible connection structure of the stent in a natural constricting structure of the anatomical tract. The flexible quality of the connection structure permits the natural constricting functions of the anatomical tract to occur. The natural closure of the anatomical constricting structure stops the flow of fluid, for example, from a target organ which indicates that the stent is properly placed within the anatomical tract.
