    • A delivery device for delivering a plurality of individual surgical fasteners is disclosed. The delivery device has a drive mechanism having a distal and a proximal end, and a first and a second opposing member. The members are moveable proximally and distally with respect to the delivery device, and individually with respect to each other. The device further includes at least one surgical fastener located between the first and the second members. Each of the at least one surgical fasteners has a proximal end and a distal end. The surgical fasteners are preferably made from a superelastic nickel titanium alloy. Additionally an actuator having at least three sequential positions is included. The first position of the actuator is for moving the drive mechanism distally. The second position is for moving the first member proximally to partially deploy the distal end of the fastener. The third position of the actuator is for moving the second member proximally, to fully deploy the distal end of the fastener.
    • 公开了用于输送多个单独外科紧固件的输送装置。 输送装置具有具有远端和近端的驱动机构,以及第一和第二相对构件。 构件可相对于输送装置向近侧和远侧移动,并且相对于彼此分开。 该装置还包括位于第一和第二构件之间的至少一个外科紧固件。 所述至少一个手术紧固件中的每一个具有近端和远端。 手术紧固件优选地由超弹性镍钛合金制成。 另外还包括具有至少三个连续位置的致动器。 执行器的第一个位置是用于将驱动机构向远端移动。 第二位置是用于将第一构件向近端移动以部分地展开紧固件的远端。 致动器的第三位置用于向近侧移动第二构件,以完全展开紧固件的远端。
