Abstract: A fall arrest system with flow-through intermediate supports which allow the travel of one or more load-connecting devices along a length of horizontal lifeline cable supported by intermediate supports. The load-connecting device having an upper cable contacting portion of greater outside diameter than the narrow opening at the bottom of the intermediate supports. In the event of a fall, the load-connecting device pulls the cable downward while the cable remains within the inner portion of said intermediate supports. Outward tension of the cable in maintained by a tension control device while the chock to the load is absorbed by said tension control device located between the cable and one of the cable-end anchors.

Abstract: The guidewire extension wire and connector assembly comprises: a guidewire extension wire having a distal end portion including, extending toward a distal end of the guidewire extension wire, a break-away neck, a reduced-in-diameter stub section and a larger-in-diameter distal stub end; an inner sleeve having an inner end fixed to the guidewire extension wire proximally of the break-away neck and an outer end extending to the larger-in-diameter distal stub end; an outer sleeve having an inner end thereof fixed to the larger-in-diameter distal stub end; and, a fixing mechanism within an outer end of the outer sleeve adapted to engage a generally cylindrical reduced-in-diameter proximal stub end of an initially inserted guidewire.
