Intraluminal stent and graft
First Claim
1. A stent-graft combination comprising a tubular stent having a plurality of hoops aligned adjacent one another along the axis of said tubular stent, each of said hoops comprising a plurality of elongate elements, with pairs of said elongate elements meeting one another and forming vertices axially pointing in a direction along the axis of the stent, wherein at least some of said vertices axially abut and are individually connected to oppositely pointed vertices of elongate elements of an adjacent hoop by separate connecting members which connect adjacent vertices so that they abut one another, further including a tubular graft member disposed circumferentially adjacent the tubular stent and wherein at least one elongate element from one hoop is continuous with a second elongate element of an adjacent hoop.
