    • A suturing apparatus configured to suture an opening extending through an outer wall of the heart, such as a transapical opening, can comprise an elongate body having a proximal end, a distal end, a tapered or rounded tip, one or more arms, and one or more needles. A handle at the proximal end of the elongate body can be configured to be manipulated from outside of the heart. The elongate body can have a substantially constant outer diameter between the handle and the distal end. The arms can hold portions of suture a distance away from the outer diameter of the elongate body. The arms can be extendable from said body from a retracted position to an extended position. The arms in the extended position can point distally and form an acute angle with a longitudinal axis of the elongate body. The plurality of needles can be movable to pass through heart tissue into engagement with the suture portions held by the arms and back through the heart tissue to draw the suture portions through the heart tissue.
    • 构造成缝合延伸穿过心脏外壁的开口(例如经脊开口)的缝合装置可以包括细长体,其具有近端,远端,锥形或圆形末端,一个或多个臂和一个 或更多针。 在细长体的近端处的手柄可构造成从心脏的外部被操纵。 细长体可以在手柄和远端之间具有基本恒定的外径。 臂可以将缝合部分与细长体的外径保持一定距离。 臂可以从所述主体从缩回位置延伸到延伸位置。 延伸位置的臂可以向远侧指向并与细长体的纵向轴线形成锐角。 多个针可以是可移动的,以通过心脏组织与由手臂保持的缝线部分接合并穿过心脏组织,以将缝线部分穿过心脏组织。
