Patent ID: 8486131

Claim:
An implantable kit for treating an aneurysmatic abdominal aorta of a human subject, the kit comprising: an endovascular stent-graft (ESG) comprising: a structural member (ESG-SM) adjustable between a radially-expanded state and a radially-compressed state; and a fluid flow guide (FFG), substantially impervious to fluids and adjustable between an expanded state and a radially-compressed state; said FFG including a proximal region along which the fluid flow guide is tubular to provide a primary conduit; and said FFG being disposed adjacent to said ESG-SM and being securely attached thereto; and an extra-vascular wrapping (EVW) comprising: at least one structural member (EVW-SM), capable of reversibly interchanging between (i) a generally cylindrical expanded state characterized by an inner diameter and a length in the direction of said aorta suitable for surrounding at least an effective portion of said ESG; and (ii) a deformed state suitable for laparoscopic delivery of said EVW from a location outside of said subject's body to a location around said aorta, and vice versa; and at least one medical textile member adapted to at least partially encircle a segment of said aneurysmatic aorta in proximity to the renal arteries, said medical textile member (a) being disposed adjacent to said EVW-SM and being securely attached thereto, and (b) comprising at least one internal macroporous layer, which comprises a polymer mesh characterized by pores ranging in dimension from 100 μm to 2 mm, the macroporous layer being adapted by means of size and shape to be positioned directly over said aneurysmatic abdominal aorta, and shaped so as to define voids dimensioned to allow free tissue ingrowth therethrough, wherein said EVW-SM and either said ESG-SM or said FFG are in reversible attachment therebetween by one or more physical members connecting directly between said ESG and said EVW, so that dislocation of the kit along the aorta is avoided.
