    • Apparatus and methods are provided, including an elongate element that is inserted into a subject's artery via a catheter, the catheter being configured to be withdrawn from the artery subsequent to the insertion. Expandable elements are disposed on the elongate element, the expandable elements comprising respective distal tips that are substantially aligned with the elongate element. During insertion of the elongate element via the catheter, the expandable elements are in contracted states thereof. In response to the withdrawal of the catheter from the artery, the expandable elements cause the artery to change a shape thereof, by the expandable elements expanding such that the distal tips of the expandable elements contact respective contact points on the wall of the artery. Subsequently, the distal tips of the expandable elements are freed from the contact points upon pulling of the elongate element. Other embodiments are also described.
    • 提供了装置和方法,包括通过导管插入受试者的动脉的细长元件,该导管构造成在插入之后从动脉中取出。 可膨胀元件设置在细长元件上,可膨胀元件包括与细长元件基本上对准的相应的远侧末端。 在通过导管插入细长元件时,可膨胀元件处于收缩状态。 响应于导管从动脉撤回,可膨胀元件使得动脉改变其形状,由可膨胀元件膨胀使得可膨胀元件的远侧末端接触动脉壁上的相应接触点。 随后,在拉伸细长元件时,可膨胀元件的远端头部从接触点脱离。 还描述了其它实施例。
