US Patent 8070790 Capture device for stent graft delivery

An apex capture device for holding proximal apices of a stent to be implanted includes a distal capture portion to be fixedly connected to a distal end of a first hollow lumen and a proximal capture portion fixedly connected to a distal end of a second hollow lumen. The distal capture portion has a longitudinal axis, a distal portion with a proximal end, and a proximal stopper having a distal side and a proximal side. At least a portion of the proximal side of the proximal stopper extends along a line that intersects a hollow first lumen. The proximal capture portion has fingers that define an interior cavity shaped to receive the proximal stopper.
