    摘要： The invention is directed to a stent delivery method and system which generally includes an elongated delivery sheath and a catheter disposed within an outer lumen of the sheath having an expandable member on its distal extremity. An expandable stent is mounted on the expandable member of the catheter. The distal portion of the sheath tapers down and is tucked within an elastic cone during transport of the stent to a stenotic region. A manipulating device is provided on the proximal end of the delivery system to effect relative axial movement between the sheath and the catheter so as to expose the stent mounted on the expandable member on the catheter within a body lumen such as a coronary artery and allow the expansion of the stent by the expansion of the expandable member. The elastic cone thereby disengages from the sheath and collapses about the distal end of the catheter. The delivery sheath has a first port in its distal end and a second port in the sheath wall proximally disposed from the distal end of the sheath. The catheter likewise has a first port in its distal end and a second port proximally disposed from the distal end of the catheter. An inner lumen extends within the distal portion of the catheter between the first and second ports and slidably receives a guiding member such as a guidewire. This system allows the stent to be delivered over a guidewire previously advanced to the desired location within a body lumen.

    摘要翻译： 本发明涉及一种支架输送方法和系统，其通常包括细长的输送护套和设置在护套的外腔内的导管，其在其远端上具有可扩张构件。 可扩张支架安装在导管的可扩张构件上。 护套的远端部分在将支架运送到狭窄区域期间逐渐变细并且被折叠在弹性锥体内。 操纵装置设置在输送系统的近端上以实现护套和导管之间的相对轴向移动，以便将安装在可扩张构件上的支架暴露在诸如冠状动脉的体腔内的导管上，并允许 通过可扩张构件的膨胀来扩张支架。 因此弹性锥体与护套分离并围绕导管的远端塌陷。 输送护套在其远端具有第一端口，并且护套壁中的第二端口从护套的远端向近侧设置。 导管同样具有其远端中的第一端口和从导管的远端向近侧设置的第二端口。 内腔在第一和第二端口之间的导管的远端部分内延伸，并且可滑动地容纳诸如导丝的引导构件。 该系统允许支架在先前推进到体腔内的期望位置的导丝上传送。

    摘要： A stent delivery system having an expandable stent in a contracted condition positioned on an expandable member, such as an inflatable balloon, disposed on the distal portion of an elongated catheter body. A guidewire extends through an inner lumen within the elongated catheter body and out its distal end. A tubular protective sheath is secured by its distal end to the portion of the guidewire which extends out of the distal end of the catheter body and fits over the rolled up stent mounted on the expandable member on the distal end of the catheter body. The catheter assembly is advanced to a desired location within a patient's body lumen, such as the patient's arterial system, with the sheath in place over the stent. Once in proper position, the guidewire is advanced distally in order to remove the attached sheath and completely expose the stent. The expandable member on the catheter is expanded to expand the stent. The stent is preferably self-locking in the expanded condition so that the expanded expandable member can be contracted and the catheter can be removed therefrom.
