<p>A branch vessel suture stent system (20) including a branch vessel suture stent (40) having a stent body (42) having a first end (44), a second end (46), and a central axis (48), the first end having a first periphery (54); and shape memory hooks (60) disposed about the first periphery, each of the shape memory hooks being attached to the first periphery at an attachment point (50), the shape memory hooks being elongated in a stressed state and looped in a parent state, each of the shape memory hooks defining a loop plane in the parent state. The shape memory hooks are substantially parallel to the central axis in the stressed state, and the first periphery at the attachment point for each of the shape memory hooks is substantially orthogonal to the loop plane for each of the shape memory hooks in the parent state. The delivery system (22) allows the main body of the branch device to expand while maintaining the hooks in an undeployed configuration using individual hypotubes (35).</p> |
