APPARATUS AND METHOD FOR DELIVERY AND DOUBLE-ENDED FIXATION OF VASCULAR GRAFTS OR STENT-GRAFTS

摘要

The present invention relates to medical techniques, more particularly to methods and apparatus dor delivery and double-ended fixation of vascular prothesis - grafts or stent-grafts to blood vessel walls in direction from inside these vessels to their outer surface. The apparatus comprises a tubular body with two expandable working heads at the free end, means for securing thereon the prosthesis ends. The heads have eight cartridges each, and each of these cartridges is provided with one basic and one standby fastener means, substantially U-shaped staples.A control mechanism is provided consisting of two control modules joined together. The apparatus is also provided with means for positioning inside a blood vessel. There is further proposed a method dor delivery and double-ended fixation of an endovascular prosthesis to a blood vessel wall.
