    • An apparatus for promoting hemostasis of a puncture formed in a blood vessel accessible through an incision tract. The apparatus includes a distal balloon having a contacted position, in which a profile of the distal balloon is sized for insertion through the blood vessel puncture, an expanded position, in which the distal balloon profile prevents passage through the blood vessel puncture. The apparatus also includes a proximal balloon spaced by a predetermined initial distance from the distal balloon and having a contracted position, in which a profile of the proximal balloon is sized for insertion through the incision tract, and an expanded position, in which the proximal balloon profile blocks passage through the blood vessel puncture. The apparatus further includes at least one catheter coupling the distal and proximal balloons to a source of pressurized fluid to selectively actuate the distal and proximal balloons between the contracted and expanded positions. And, the apparatus includes at least one rigid positioner associated with the at least one catheter to facilitate movement of the distal and proximal balloons proximally through the incision tract. The catheter has a flexible wall portion extending proximally of the distal and proximal balloons to facilitate everting of the distal and proximal balloons as the catheter is proximally withdrawn from the incision tract.
    • 一种用于促进形成在通过切口可通过的血管中形成的穿刺止血的装置。 该装置包括具有接触位置的远端球囊,其中远端球囊的轮廓的尺寸设置成插入通过血管穿刺,扩张位置,其中远侧球囊形状防止通过血管穿刺。 该装置还包括与远端球囊隔开预定的初始距离并且具有收缩位置的近端球囊,其中近端球囊的轮廓的尺寸被设计成用于插入通过切开管道,以及扩张位置,其中近端球囊 轮廓块通过血管穿刺。 该装置还包括至少一个导管,其将远端和近端气囊联接到加压流体源,以选择性地致动收缩和扩张位置之间的远端和近端气囊。 并且,该装置包括与至少一个导管相关联的至少一个刚性定位器,以便于远端和近端球囊向近侧移动通过切口。 导管具有在远端和近端气囊的近侧延伸的柔性壁部分,以便当导管从切开道向近端退出时便于远端和近端气囊的远端。
