Delivery device, delivery system, stent graft and a support structure

Abstract

A delivery device ( 1 ) for an endoprosthesis ( 2 ). The endoprosthesis ( 2 ) is preferably an endoprosthesis for treating an aneurysm. The delivery device ( 1 ) comprises an outer sheath ( 3 ) and an inner tube ( 4 ). The inner tube ( 4 ) is arranged within the outer sheath ( 3 ) and at least one restraining tube ( 5 , 30 ). The restraining tube ( 5 , 30 ) is for holding the endoprosthesis ( 2 ) in a compressed configuration. The restraining tube ( 5 , 30 ) is arranged between the outer sheath ( 3 ) and the inner tube ( 4 ). The outer sheath ( 3 ), the inner tube ( 4 ) and at least one restraining tube ( 5 , 30 ) are coaxial. The restraining tube ( 5 , 30 ) includes at least one axial elongation ( 6 ) extending from a distal end portion of the restraining tube. The at least one axial elongation ( 6 ) is adapted to be laced through portions of the endoprosthesis ( 2 ).
