腔内装置和方法
摘要：
本申请涉及腔内装置和方法。一种构造成用于在脉管内展开期间精确定位的腔内装置。所述腔内装置可以是钉、支架、血管植入物或其他类型的植入物。所述腔内装置可以具有有波状构造的周向构件，所述波状构造具有多个内顶点和外顶点以及在其间延伸的支柱。支柱中的两个可以用于建立用于在展开期间使装置精确定位的支脚。一种放置腔内装置的方法可包括撤回外部护套以使得腔内装置的一部分早于腔内装置的其余部分扩张。
摘要（英）：

An endoluminal device can be configured for precise positioning during deployment within a vessel. The endoluminal device can be a tack, stent, vascular implant or other type of implant. The endoluminal device can have circumferential member with an undulating configuration having multiple inward and outward apexes and struts extending therebetween. Two of the struts can be used to establish a foot for the precise positioning of the device during deployment. A method of placing the endoluminal device can include withdrawing an outer sheath such that a portion of the endoluminal device is expanded prior to the rest of the endoluminal device.
