    • A holding member for an implantable cardiac device facilitates tether attachment and removal, at time of implant, and snaring, or otherwise capturing, for subsequent explant. Preferably located in proximity to a proximal end wall of a shell of the device, the holding member includes a strut portion, being spaced proximally apart from the proximal end wall, a waist portion, defining a recess, and an engagement section, extending between the strut portion and the waist portion and overhanging the recess. The waist portion may either extend between the strut portion and the proximal end wall, or be formed in the shell, distal to the proximal end wall. Alternately, the holding member includes a loop element and an engagement element coupled thereto, between first and second segments thereof. The segments are initially formed to give the loop element an opening, and have a flexibility to be compressed together.
    • 用于可植入心脏装置的保持构件促进在植入时的系链附着和移除,并且用于后续外植体的瘢痕或其它捕获。 优选地,所述保持构件优选地位于所述装置的壳体的近端壁附近,所述支撑构件包括支撑部分,所述支柱部分与所述近端壁向近侧间隔开,限定凹部的腰部和接合部分 支撑部分和腰部,并且突出于凹部。 腰部可以在支柱部分和近端壁之间延伸,或者形成在远离近端壁的壳体中。 或者,保持构件包括环形元件和联接到其上的接合元件,在其第一和第二段之间。 这些段最初形成为使环形元件成为开口,并且具有被压缩在一起的柔性。
