摘要： An aortic occlusion and perfusion device includes an expandable member configured to expand within the aorta to secure the device within the aorta, and a catheter extending proximally from the expandable member and in fluid communication with the expandable member. The catheter can define a plurality of openings along its length through which blood can pass with one or more of the openings located proximal to the expandable member and one or more of the openings located within the expandable member. The device can also include a flow control sheath disposed around the catheter member such that axial movement of the flow control sheath relative to the catheter selectively occludes or uncovers one or more of the openings located proximal to the expandable member.

A catheter extends proximally from the expandable member in fluid communication with the expandable member. The catheter defines openings through which blood can pass with one or more of the openings located proximal to the expandable member and one or more of the openings located within the expandable member. The catheter defines a lumen in fluid communication with the one or more openings located within the expandable member, the lumen terminating at a terminus such that the lumen is not in fluid communication with a distal end portion of the catheter. A flow control sheath is disposed around the catheter proximal to the expandable member such that axial movement of the flow control sheath relative to the catheter selectively occludes or uncovers the one or more openings located proximal to the expandable member.

摘要： This disclosure relates generally to systems and methods for occluding vessels of the heart and inducing cardioplegic arrest to facilitate the performance of cardiac procedures. An aortic occlusion and perfusion device includes an expandable member configured to expand within the aorta to secure the device within the aorta, and a catheter extending proximally from the expandable member and in fluid communication with the expandable member. The catheter can define a plurality of openings along its length through which blood can pass with one or more of the openings located proximal to the expandable member and one or more of the openings located within the expandable member. The device can also include a flow control sheath disposed around the catheter member such that axial movement of the flow control sheath relative to the catheter selectively occludes or uncovers one or more of the openings located proximal to the expandable member.

摘要翻译： 本公开一般涉及用于闭塞心脏血管并诱导心脏停搏的系统和方法，以促进心脏手术的进行。 主动脉闭塞和灌注装置包括构造成在主动脉内扩张以将装置固定在主动脉内的可扩张构件，以及从可扩张构件向近侧延伸并与可扩张构件流体连通的导管。 导管可以沿着其长度限定多个开口，血液可以穿过该开口，其中一个或多个开口位于可扩张构件的近侧，以及位于可扩张构件内的一个或多个开口。 该装置还可以包括设置在导管构件周围的流动控制鞘，使得流动控制护套相对于导管的轴向运动选择性地封闭或露出位于可扩张构件附近的一个或多个开口。
