    • A vascular closure device includes a release component, a delivery component, a sealing device and at least one actuator. The release component is elongate along a longitudinal direction, and defines a distal end and a proximal end. The delivery component extends along the release component such that at least the release component is movable relative to the delivery component. The delivery component includes a delivery tube body and defines a delivery tube channel. The sealing device has a toggle that is at least partially disposed within the release tube, a suture that is attached to the toggle and extends through the delivery tube channel, and a plug that is attached to the suture proximal to the toggle. The actuator is coupled to the release component and is in communication with the suture such that actuation of the actuator causes (i) the release component to move the proximal direction relative to the delivery component so as to release the toggle from the release component, and (ii) the suture to be pulled in a proximal direction to thereby place the filament in tension and urge the toggle against a distal end of the delivery component such that the toggle is oriented in a sealing position.
    • 血管闭合装置包括释放部件,输送部件,密封装置和至少一个致动器。 释放部件沿着纵向方向是细长的,并且限定远端和近端。 递送部件沿释放部件延伸,使得至少释放部件可相对于递送部件移动。 输送部件包括输送管体并限定输送管通道。 密封装置具有至少部分地设置在释放管内的肘节,附接到肘节并且延伸穿过输送管通道的缝合线,以及附接到肘节近侧的缝合线的插塞。 致动器联接到释放部件并且与缝线连通,使得致动器的致动导致(i)释放部件相对于递送部件移动近侧方向,以从释放部件释放肘节,以及 (ii)将缝线沿近端方向拉动,从而将细丝置于拉伸状态,并将肘节推动抵靠输送部件的远端,使得肘节定位在密封位置。
