    摘要： Embodiments of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such embodiments can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some embodiments can include a sheath with inner and outer layers, where a folded portion of the inner layer extends through a slit in the outer layer and a portion of the outer layer overlaps the folded portion of the inner layer. Some embodiments include an elastic outer cover positioned outside the outer layer. Embodiments of the present expandable sheath can avoid the need for multiple insertions for the dilation of the vessel, thus offering advantages over prior art introducer sheaths.

    摘要翻译： 可扩张护套的实施例可以与导管组件一起使用以将诸如心脏瓣膜的假体装置引入患者体内。 这样的实施例可以通过允许引导器护套的一部分临时膨胀以适应输送装置来最小化对容器的创伤，然后一旦假肢装置通过就恢复到原始直径。 一些实施例可以包括具有内层和外层的护套，其中内层的折叠部分延伸穿过外层中的狭缝，并且外层的一部分与内层的折叠部分重叠。 一些实施例包括位于外层外部的弹性外盖。 本发明的可扩张护套的实施例可以避免需要多次插入用于扩张容器，从而提供优于现有技术的导引器护套的优点。
