A transfer set for transferring fluid, including drugs, vaccines, medicaments, solutions and the like, between a first container, such as a conventional vial, and a second container, such as a conventional syringe having a unique multipurpose resealable member. The transfer set assembly includes an elastomeric tubular fluid transfer and resealable valve member preferably including an open end mounted on the pierceable closure or stopper of a vial and a generally closed distal end having a longitudinal slit and a piercing member is telescopically received within the fluid transfer valve member having a piercing end opposite the pierceable closure. The fluid transfer valve member is preferably formed of silicone and is surrounded by a generally tubular luer connector member having an open end mounted on the pierceable closure and a distal end having male luer threads. This assembly is enclosed within a cup-shaped closure and the assembly is retained to the first container or vial by a collar preferably secured to the vial by crimping. Upon removal of the cup-shaped closure, fluid communication between the vial and a second container, such as a syringe, is achieved by threading the luer connector of the syringe on the luer threads of the tubular luer connector member, which drives the tip through the slit of the elastomeric fluid transfer valve member against the distal end of the piercing member, driving the piercing end through the pierceable closure. In the preferred embodiment, the piercing member includes a generally longitudinal channel which establishes communication between the vial and the syringe through the tubular fluid transfer valve member.

The squeezing mechanism includes a substantially rigid base and a substantially rigid displaceable actuator. The tubular material is mounted on the base of the squeezing mechanism, and the actuator is aligned to alternately squeeze the tubular material against the base to pump fluid out of the chamber, and release the tubular material from the base to draw fluid into the chamber. A steam appliance incorporating a one-way tubular pump is also provided.

A valve seat portion 20 has a nearly tubular shape, at the bottom of which a circular opening portion 23 which functions as a valve seat is formed. A valve portion 10 has a ring-shaped supporting portion 11 which is disposed inside the valve seat portion 20. A valve body 12 has a shape corresponding to the circular opening portion 23, and multiple coupling portions couple the supporting portion 11 and the valve body 12. In the valve portion 10, the valve body can move between a closed position in which the valve body closes the opening portion 23 in the valve seat portion 20 and an open position in which the valve body opens the opening portion 23 by the flexibility of the four coupling portions 13.

A variable length endovascular prosthesis adapted to prevent endoleaks is provided that includes a substantially tubular first graft member having an interior surface, an exterior surface, and a proximal end, and a substantially tubular second graft member slidably engaged coaxially within the first graft member. The prosthesis further includes a substantially tubular fluid-tight connecting member attached at one end to the first graft member and attached at another end to the second graft member. The connecting member is axially compressible and expandable to facilitate engagement of the second graft member within the first graft member while maintaining a seal between the graft members.

A fluid transfer system having improved stress accommodation properties and thermal insulation properties is provided. The fluid transfer system includes a fluid transfer conduit comprising a plurality of concentric tubes configured to divide and distribute an axial stress induced in the fluid transfer conduit to each of the tubes and a vacuum cavity between the fluid transfer conduit and a structural support of the fluid transfer system to insulate fluid from a surrounding environment.

The invention is directed to a blood pressure monitoring device comprising a central parts mounting module and to a method of manufacturing this parts mounting module. According to the invention fluid channels are produced by gas injection into the interior of the parts mounting module, the walls bounding the fluid channels being completely formed by the material of the parts mounting module. The injection of gas continues for as long as a core of the parts mounting module is still in the liquid phase in the area of the fluid channel, whilst an outer area surrounding the core has already solidified, so that the pressure fluid expels the liquid core area, producing a tubular fluid channel.
