An osmotically inflatable seal to treat endoleaks of type 1, following endovascular aneurysm repair

Résumé

Stent-grafts of various designs are currently used in endoluminal treatment of abdominal aortic aneurysm. Two of the remaining possible complications are endoleaks and stent migrations. To treat endoleaks of type 1, a new system is studied here: An inflatable osmotic seal. It is set up at the extremities of the endograft and swollen using osmotic process against the vessels in case of endoleak without any invasive re-intervention. Mechanical modeling of the device and finite element simulations are performed to evaluate the efficiency of the seal and the consequences on the arteries as function of the osmotic pressure.
