Abstract
An arterial graft device and a process for positioning the same, wherein said device comprises a first part positioned by conventional techniques within the artery, and a second part positioned on the first part by guiding means which are provided on the first part so as to prevent a catheter guidewire—whereby said second part is positioned in place—from deviating and damaging arterial walls.
Claims9
An arterial graft device of the kind comprising two parts to be inserted one at a time within the artery to be repaired and which should be connected one to the other within the artery to which access is attained by catheterizing techniques, wherein the first of said parts comprises a connecting opening where the second part is engaged thereto, characterized in that said first part has guiding means which form a funnel for introducing a guidewire of a catheter and said second part of the graft device.
A graft device according to any of the foregoing claims, characterized in that said coned vertex and said graft device form a bifurcated aortic endoluminal graft disposed on the infra-renal aorta and the iliac arteries, said first part of the graft forming the main aortic body and an iliac segment, and said second part forming the other iliac segment.
A process for positioning an arterial graft device according to any of the foregoing claims, wherein said first part of the device is inserted within the artery to be repaired and is positioned within the artery, a catheter guidewire being then inserted whereby said second part of the graft device is carried so as to be connected to said connecting opening of said first part of the device, characterized in that said guidewire is guided towards said artery to be repaired and, once there, the guidewire is funneled through a coned passage becoming narrower towards said connecting opening and which leads said second part of the graft device along said guidewire and along said coned passage until said second part is connected to said connecting opening of the first part of the graft device.
