A removable stent (10) for placement within a portion of the anatomy of a patient is provided. The stent (10) includes a scaffolding having struts (12,14) that is configured to define a substantially cylindrical member having a proximal end and a distal end. The stent also includes a suture (16) intertwined about at least a portion of the struts, wherein the suture (16) includes at least one loop (18) such that a force applied to the loop (18) does not result in purse-stringing. Additionally a second suture (16) may pass circumferentally through the loops (18). Applying a force on the second suture (16) causes the stent (10) to reduce in diameter.

L'invention concerne un stent amovible destiné à être placé dans une partie du corps d'un patient. Ce stent comprend une structure comportant des entretoises, conçue pour former un élément sensiblement cylindrique possédant une extrémité proximale et une extrémité distale. Le stent comprend également un fil de suture enroulé sur au moins une partie des entretoises, le fil de suture comportant au moins une boucle. Cette configuration permet d'éviter que la force appliquée sur la boucle forme un cordon de bourse.
