摘要： A hemostasis valve including a collapsible membrane in a portion of a through-lumen. Fluid pressure in a chamber surrounding the collapsible membrane assists in sealing the collapsible membrane around an operating device inserted through the hemostasis valve. Different mechanisms for mechanically deforming the collapsible membrane to assist in sealing are disclosed. Also, a system for continuously flushing a vascular catheter connected to a hemostasis valve at a rate of 0.10 to 10.0 cubic centimeters per minute, and a hemostasis valve assembly including an expandable reservoir which stores liquid volume under pressure.

摘要： A multi-section stent includes a connecting structure that allows the stent sections to move and flex relative to one another. For deployment and positioning, the connecting structure connects the multiple stent sections and holds the stent sections substantially stationary relative to one another. Following deployment, the connecting structure allows the multiple stent sections to move relative to one another. Moveable stent sections enable flexure of the stent upon deployment within a body lumen. This flexing structure allows better conformance of the stent to the shape of the body lumen, and exerts less overall pressure against the lumen wall, reducing the potential for trauma. Upon deployment, the multiple stent sections may be completely detached from one another. Alternatively, the stent sections may remain partially connected in a manner that allows substantial independent movement. The connecting structure can be manufactured to separate upon deployment, for example, by breaking or degrading within the body lumen in which the stent is positioned.
