Abstract:
1. A combination of a catheter based stent-graft delivery system and a stent-graft, the combination comprising: a holding device which is integral with the catheter based stent-graft delivery system, the holding device including a wire holder slidably engaged to an inner member of the catheter based stent-graft delivery system, engagement wires, a wire guide having an inner diameter and fixedly mounted to the inner member of the catheter based stent-graft delivery system distal to the wire holder, and a distal receiver fixedly mounted to the inner member of the catheter based stent-graft delivery system distal from the wire guide; a stent-graft; eyelets integral with the stent-graft and extending from the end thereof, the engagement wires originating from the wire holder and passing through the wire guide and the eyelets and terminating in free ends in the distal receiver, the wire holder being configured to slide proximally on the inner member, thereby retracting the engagement wires from the distal receiver and eyelets and into the wire guide; wherein the inner member has a distal end and a proximal end and the wire holder has a distal end and a proximal end, and the distal end of the wire holder is substantially closer to the distal end of the inner member than the proximal end of the inner member; and a collar having an outer diameter and a distal end and a proximal end, the collar coaxially and fixedly mounted on the inner member proximal to the proximal end of the wire holder such that the distal end of the collar is substantially closer to the distal end of the inner member than the proximal end of the inner member, wherein the outer diameter of the collar is greater than the inner diameter of the wire holder, such that the collar can stop the proximal motion of the wire holder on the inner member.
