An implantable kit for treating an aneurysmatic abdominal aorta (110, 120, 130) of a human subject, the kit comprising: a. an endovascular stent-graft, ESG, comprising: i. a structural member, ESG-SM, adjustable between a radially-expanded state and a radially-compressed state; and ii. a fluid flow guide, FFG formed of textile strands, 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 b. an extra-vascular wrapping (125, 135), EVW, said EVW (125, 135) 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 (110, 120, 130) suitable for surrounding at least an effective portion of said implanted ESG; and (ii) a deformed state suitable for laparoscopic delivery of said EVW (125, 135) from a location outside of said subject's body to a location around said aorta (110, 120, 130), and vice versa, characterized in that said EVW (125, 135) further comprises 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 said medical textile member further (b) comprises at least one internal macroporous layer and at least one external microporous layer. a. an endovascular stent-graft, ESG, comprising: i. a structural member, ESG-SM, adjustable between a radially-expanded state and a radially-compressed state; and ii. a fluid flow guide, FFG formed of textile strands, 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 i. a structural member, ESG-SM, adjustable between a radially-expanded state and a radially-compressed state; and ii. a fluid flow guide, FFG formed of textile strands, 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 b. an extra-vascular wrapping (125, 135), EVW, said EVW (125, 135) 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 (110, 120, 130) suitable for surrounding at least an effective portion of said implanted ESG; and (ii) a deformed state suitable for laparoscopic delivery of said EVW (125, 135) from a location outside of said subject's body to a location around said aorta (110, 120, 130), and vice versa, characterized in that said EVW (125, 135) further comprises 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
