Short body endoprosthesis

   
   

The invention comprises, inter-alia, endoprosthetic implants for treating vascular defects, including abdominal aortic aneurysms. Implants according to the invention have a short main body that can be positioned within a patient's aorta at a position above the renal end of an aortic aneurysm. The short main body includes a proximal, or renal, face that redirects the flow of blood into the openings of channels that can carry blood past the aneurysm. In this way, the flow of blood through the aorta is diverted into the two passageways and through the main body of the implant. Fluid exiting the implant can be carried by leg extensions and delivered to a healthy part of the patient's aorta or the iliac arteries. Accordingly, the implant provides a system for allowing blood traveling through the aorta to be carried by a vascular graft that spans an aortic aneurysm, thereby relieving fluid pressure on the thin wall of aortic aneurysm, and reducing the risk of death caused by a ruptured aneurysm.

A invenção compreende, implants inter-alia-alia, endoprosthetic para defeitos vascular de tratamento, including aneurysms aortic abdominal. Os implants de acordo com a invenção têm um corpo principal curto que possa ser posicionado dentro do aorta de um paciente em uma posição acima da extremidade renal de um aneurysm aortic. O corpo principal curto inclui um proximal, ou renal, enfrente que dirija de novo o fluxo do sangue nas aberturas das canaletas que podem carregar o sangue após o aneurysm. Nesta maneira, o fluxo do sangue através do aorta é desviado nos dois passageways e através do corpo principal do implant. O líquido que retira o implant pode ser carregado por extensões do pé e ser entregado a uma parte saudável do aorta ou dos arteries iliac do paciente. Conformemente, o implant fornece um sistema permitindo o sangue que viaja através do aorta a ser carregado por um graft vascular que meça um aneurysm aortic, aliviando desse modo a pressão fluida na parede fina do aneurysm aortic, e reduzindo o risco da morte causado por um aneurysm rompido.
