The Big Short, page-4

From what I know the work with Cook commenced in 2014 (based on the feasibility study ann, 25 Mar 2015 where it mentions scoping studies were done in the previous year). I'm not a scientist, but here are some of the patents I think could be relevant. Twin and others will probably be able to shed more light:


ENDOVASCULAR STENT GRAFT ASSEMBLY AND DELIVERY DEVICE
Publication number: 20160106564
Abstract: A pre-loaded delivery device that facilitates accurate placement of a stent graft assembly in the aorta is disclosed. A stent graft is carried on the delivery device and held in a pre-deployment configuration by a sheath. A split in the sheath facilitates the pre-cannulation of one or more branch arteries extending from the aorta before the stent graft is fully released in the aorta. The stent graft comprises a tubular body having at least one scalloped fenestration formed in one end of the graft material and at least one fenestration formed in the graft material of the main tubular body. A helical internal side branch extends from the fenestration within the lumen of the main tubular body. The helical side branch is configured to curve at least partially around the scalloped fenestration. The assembly further comprises a connection stent graft extending from the fenestration into a branch vessel.

COMPLIANT SLEEVE FOR VASCULAR BALLOON
Publication number: 20160082230
Abstract: The present disclosure relates to vascular balloon catheters having one or more sleeves disposed around at least a portion of the balloon. The balloon may be non-compliant or semi-compliant and its behavior may be modified by using the sleeve. The behavior of the balloon may be modified in any manner by the sleeve where a variable length of the balloon expands before the entire length of the balloon expands.

LOW PROFILE NON-SYMMETRICAL STENT
Publication number: 20160074183
Abstract: Various stents and stent-graft systems for treatment of medical conditions are disclosed. In one embodiment, an exemplary stent-graft system may be used for endovascular treatment of a thoracic aortic aneurysm. The stent-graft system may comprise proximal and distal components, each comprising a graft having proximal and distal ends, where upon deployment the proximal and distal components at least partially overlap with one another to provide a fluid passageway therebetween. The proximal component may comprise a proximal stent having a plurality of proximal and distal apices connected by a plurality of generally straight portions, where a radius of curvature of at least one of the proximal apices may be greater than the radius of curvature of at least one of the distal apices. The distal component may comprise a proximal z-stent coupled to the graft, where the proximal end of the graft comprises at least scallop formed therein that generally follows the shape of the proximal z-stent.

There were others listed in the correct time-frame, but I've run out of time to keep reading this morning.

All IMHO, DYOR, FWIW, blah blah blah....
