Abstract
In accordance with the invention, there are provided medical devices for providing a fluid passage between two areas in the body. An embodiment of the present invention relates to a stent comprising a tubular member comprising a distal transition region and a proximal transition region adapted to provide the ability for the stent to accommodate the dynamic urinary tract anatomy that stretches and relaxes. The distal transition region and the proximal transition region is adapted to exhibit a physical property that provides both longitudinal elasticity, allowing for stretch and recoil, as well as radial elasticity, allowing for bending and recovery.
