Abstract:
A multi-component endoluminal graft assembly for repairing a blood vessel affected by one or more lesions, wherein the one or more lesions exist in a region proximate to one or more ostiums of branches of the vessel, the assembly being formed for insertion into the vessel in a manner such that the one or more lesions are repaired without the blood flow through the one or more branches being blocked by the assembly, the multi-component graft assembly comprising:an outer frame stent for endoluminaly affixing to the blood vessel, the outer frame stent forming a supportive non-impervious wall permitting blood flow therethrough; and at least one hollow tubular stent-graft, independent of the outer frame stent, adapted to be coaxially locatable within said outer frame stent after the outer frame stent is deployed within a blood vessel and affixable to the outer frame stent at a selective position between ends of the outer frame stent, a total length of all stent-grafts in the assembly being less than a length of the outer frame stent by at least a length of the one or more ostiums; whereby the outer frame stent is structured to extend, when in use, all along the one or more lesions of the vessel and over any of the one or more ostiums located between the ends of the outer frame stent, and the at least one tubular stent-graft extends, when in use, into the outer frame stent along a selective portion of the frame stent, but not into a region of the one or more ostiums, for occluding only the one or more lesions of the vessel and leaving the one or more ostiums unoccluded for maintaining a free blood flow within the vessel and the one or more branches.
