Abstract

Medical devices, such as drainage stents, having coiled structures are useful in draining body fluids. A medical device has a first elongated section with a first cross-sectional area and a second elongated section with a second cross-sectional area.
The second elongated section extends from the first elongated section. The second cross-sectional area is smaller than the first cross-sectional area. The second elongated section is or has at least one coiled structure with a plurality of turns, such as a helical coil tail.
