Title:
多区分ステント
Document Type and Number:
Japanese Patent JP4336049
Kind Code:
B2
Abstract:
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.
