Claim Text:
1. A system for occluding a biological lumen, comprising: an occlusive implant having a proximal hub and a distal hub that are movable towards each other; an elongate pusher having an inner lumen; an engagement element having a proximal portion and a distal portion, wherein the proximal portion is secured within a sidewall of the elongate pusher such that the engagement element is not wholly slidable with respect to the pusher and wherein the engagement element is a flexible wire or thread; and a control wire slidably received within the inner lumen of the pusher, wherein a distal end of the control wire is releasably coupled to the distal hub of the implant such that the distal hub of the implant is moveable with the control wire and releasable from the control wire, wherein the proximal hub of the implant comprises a proximal end having a lumen through which the control wire can slide and a side window located distal to the proximal end of the proximal hub, and the distal portion of the engagement element is adapted to pass through the side window and engage with the control wire to maintain coupling of the proximal hub to the pusher, wherein the engagement element is releasably coupled to the control wire such that no portion of the engagement element extends through an open distal end of the pusher through which the control wire extends, and wherein the engagement element can be released from the control wire and the proximal hub upon retraction of the control wire from the proximal hub.
