    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 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.

    摘要: A valve system is provided that includes a valve connector that has a portion of a first passageway. The valve connector includes a suction port and an introduction port that are spaced apart and in substantially parallel alignment. The suction port and the introduction port are manipulable to establish fluid communication between the portion of the first passageway and the suction port or the introduction port. The valve connector may have a rotatable outer cap that includes the suction port and the introduction port. The cap being configured to facilitate manipulation of the suction port and the introduction port for establishing fluid communication with the portion of the first passageway. The introduction port may include a normally closed valve. The valve connector may be attached to a dual lumen nasogastric tube. In an alternate embodiment, the valve connector further includes a portion of a second passageway that includes a relief port. The relief port can include a one-way valve.

    摘要: A valve system is provided having a housing including a first end, a second end and a first passageway. The housing has a first port and a second port. A valve member is disposed within the housing and movable relative thereto. The valve member defines a portion of the first passageway that includes a first opening configured for alignment and sealed fluid communication with the first port and the second port. The portion of the first passageway further includes a second opening having a greater relative dimension than the first opening. The valve member is manipulable to establish sealed fluid communication between the first opening and the first port or the second port while maintaining continuous sealed fluid communication between the second opening and the first passageway adjacent to the second end of the housing. The valve member can be disposed within the housing for rotation relative thereto.
