A FENESTRATED ENDOPROSTHESIS FOR THE CORRECTION OF AORTIC ANEURYSMS

摘要

A fenestrated endoprosthesis for the correction of aortic arch aneurysms comprising: a stent (20) having a first oblong lateral hole (23) having an area equal to the total area occupied by the innominate artery (11) and by the carotid artery (12); said stent (20) comprises a metal skeleton (21) covered with a fabric (22); characterized by comprising a flexible sac (30) that covers said stent (20) covered with fabric (22); said sac (30) comprises a second lateral hole (32) having an area larger than said first hole (23), so that the edges (26) of said stent (20) covered with fabric (22) that delimit said first hole (23) are visible; the edges (33) of said sac (30) that delimit the hole (32) are welded to said stent (20) covered with fabric (22); a volume (31) is created between said stent (20) covered with fabric (22) and said sac (30); said volume (31) is filled with a polymer.
