    • Described here are closure devices and methods for ligating tissue, such as the left atrial appendage. The closure devices may comprise a snare loop assembly comprising a snare and a suture loop releasably attached thereto, and a snare control. The closure devices may further comprise one or more reference markings, wherein the relative positioning between a portion of the snare control and the reference markings provides an indication of the diameter of the snare loop assembly. In some variations, when the snare loop assembly is closed around a tissue such as the left atrial appendage, the measured diameter of the snare loop assembly may help a user determine whether the snare loop assembly has been properly positioned relative to the tissue, as well as the approximate size that a suture loop may have when released from the snare loop assembly.
    • 这里描述了用于结扎组织的闭合装置和方法,例如左心耳。 闭合装置可以包括圈套组件,其包括可释放地附接到其上的圈套和缝合线环以及圈套控制。 闭合装置还可以包括一个或多个参考标记,其中圈套控制部分和参考标记之间的相对定位提供了圈套环组件的直径的指示。 在一些变型中,当围绕诸如左心耳的组织围绕圈套环组件时,圈套环组件的测量直径可以帮助用户确定圈圈组件是否已经相对于组织正确定位 作为当从圈套环组件释放时缝合线圈可能具有的大致尺寸。
