An apparatus for triggering a plurality of anchor launchers, the apparatus comprising: a plurality of actuators housed in a housing (400), each of the actuators having (a) a channel (402) that runs through the housing (400) in a proximal-to-distal direction, (b) a shoulder (404) disposed adjacent to the channel (402), (c) a compressed spring (406) disposed in a distal portion of the channel (402), the spring (406) having a fixed distal end and a movable proximal end, and the channel (402) being configured to permit expansion of the spring (406) in a proximal direction, (d) a tab (408) that is affixed to the proximal end of the spring (406), wherein the tab (408) is configured to be movable between a first position in which movement of the tab (408) in a proximal direction is blocked by the shoulder (404), and a second position in which movement of the tab (408) in a proximal direction is not blocked by the shoulder (404), wherein the channel (402), the shoulder (404), the spring (406) and the tab (408) are configured so that, when the tab (408) is moved from the first position to the second position, the spring (406) will expand within the channel (402), with the proximal end of the spring (406) moving in a proximal direction, and (e) a pull wire (28) having a proximal end that is attached to the spring (406) or the tab (408) and a distal portion that extends to the anchor launcher, wherein, when the proximal end of the spring (406) moves in the proximal direction, the pull wire (28) is pulled in the proximal direction.
