    摘要: A dual lumen catheter may be provided with one or more stents in a stent-deployment lumen and a wire guide disposed through a wire guide lumen. The wire guide may be directed to a target site in a patient body such as a biliary stricture. The catheter may be directed along the wire guide until it is in or adjacent the target site. A distalmost stent may be advanced out a distal side-facing aperture of the stent-deployment lumen into the target site by a pusher member that advances the stent or that holds the stent in place while the catheter is proximally withdrawn from around the stent. With the wire guide remaining substantially in place, the stent-deployment lumen can be reoriented and the steps repeated to place a second (and, if desired, subsequent) stent(s) next to—and generally parallel with—the first stent.

    摘要: A collapsing structure for collapsing the crowns of a stent and method of use thereof are described. The collapsing structure comprises an inner filament engaged to an outer filament. The outer filament is interwoven through at least a portion of the crowns of the stent end so as to create a plurality of loops. The inner filament is interwoven through at least a portion of the loops of the outer filament. Pulling on the inner filament causes the loops of the outer filament to be pulled radially inward, thereby pulling the crowns towards each other to collapse the stent end.
