摘要： 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 at least a portion of which comprises a reinforcement structure. The tubular member includes a wall and an axial lumen therein having a lumen surface. The reinforcement structure extends at least a portion of a length of the body portion adjacent the distal end portion. One advantage of this embodiment of the invention is, for example, that the reinforcement structure increases patient comfort by providing enhanced flexibility. A second advantage of this embodiment of the invention is, for example, that the reinforcement structure improves axial stiffness and radial stiffness allowing for a thinner tubular member wall thickness and larger lumen diameter.

摘要： The present invention provides embodiments of medical devices that provide for fluid drainage while maintaining patient comfort. An embodiment of the present invention provides a stent comprising a body portion and a kidney curl portion, the body portion comprising a tubular member having an axial lumen therein adapted to provide fluid communication from one body location to another. The kidney curl portion comprises an elongated filament that has a three-dimensional configuration that substantially conforms to the three-dimensional randomly convoluting calyx space of a kidney. In another embodiment, the kidney curl portion comprises a plurality of petals adapted to flare outwardly from the body portion distal end when in a free state in the space of a kidney so as to prevent the migration of the kidney curl portion into the ureter.
