Abstract
Stent graft consisting of a stent (1) comprising a plurality of ring segments (3, 4) having a meandering configuration arranged side by side and connected with each other by connecting webs (6), and at least one membrane (2) covering the entire outer side of the stent (1), being wrapped inwards around the ends of the stent and fixed between loops of ring segments (4) and connecting webs (6) that join the adjacent ring segments (3, 4) with each other, wherein the membrane (2) is fixed between at least two loops of the second ring segment (4), viewed from the ends of the stent (1), and the connecting webs (6) to the neighboring terminal ring segment (3).
Claims18
A stent graft consisting of a stent (1) and at least one membrane (2), the stent having two stent ends, an outer side and an inner side of the stent, the stent comprising a plurality of ring segments (3, 4), each of the ring segments having a meandering configuration thus creating loops with arches and valleys, the ring segments being arranged side by side and being connected with each other by connecting webs (6), with a terminal ring segment (3) being located at each end of the stent and a second ring segment (4) being located adjacent to the terminal ring segment, loops of the second ring segments alternately differ in length resulting in short loops (4A) and long loops (4),
- the at least one membrane (2) covering the entire outer side of the stent (1), and being folded inwards around at least one end of the stent and fixed between loops of the second ring segment (4) and connecting webs (6) that join the second ring (4) and the terminal ring segment (3),
- wherein the membrane (2) is fixed by clamping the membrane (2) between at least two loops of the second ring segment (4) and the connecting webs (6) connecting the second ring segment (4) and the adjacent terminal ring segment (3).
