    • The present invention relates to a stent delivery system in which a catheter carries on its distal end portion a stent which is held in place around the catheter prior to and during percutaneous delivery by means of one, and preferably two, end sleeves. The sleeves are positioned around the catheter with one end portion of each sleeve associated thereto. The other end of each sleeve overlaps an end portion of the stent to hold it in place on the catheter in a contracted condition. The present invention provides an improvement with respect to lubrication of the sleeve prior to its assembly with the catheter. A preferred way of lubricating the sleeve is by incorporating a lubricant additive within the sleeve composition.
    • 支架输送系统技术领域本发明涉及一种支架输送系统,其中导管在其远端部分承载支架,该支架通过一个,优选两个端部套筒在经皮输送之前和之后被保持在导管周围的适当位置。 袖子围绕导管定位,每个套筒的一个端部与其相关联。 每个套筒的另一端与支架的端部重叠,以在收缩状态下将其保持在导管上的适当位置。 本发明提供了在与导管组装之前套筒的润滑方面的改进。 润滑套筒的优选方式是通过在套筒组合物中引入润滑剂添加剂。
