  • Prothesis having pivoting fenestration
    Patent number: 9808334
    Abstract: The present disclosure relates to an endoluminal prosthesis, such as a stent graft that includes one or more fenestrations to accommodate endovascular disease, such as an aneurysm in cases where one or more side branches is involved. In one aspect, the prosthesis includes fenestrations that are pivotable to accommodate the dynamic geometry of the aortic branches. In another aspect, the pivotable fenestrations include a first perimeter, a band of flexible material attached and surrounding the first perimeter, and a second perimeter attached to and surrounding the band of flexible material. The first perimeter, band of flexible material, and second perimeter have a geometric shape. In one aspect, the prosthesis includes at least three pivotable fenestrations.

  • Systems and methods for maintaining perfusion of branch vessels
    Patent number: 9808364
    Abstract: An endoluminal prosthesis comprises a graft having a tubular body comprising proximal and distal ends, inner and outer surfaces, and partially and fully deployed states. A temporary channel is disposed external to the outer surface of the graft in the partially deployed state. The temporary channel begins at one of the proximal and distal ends of the graft, and extends along only a portion of a longitudinal length of the graft. The temporary channel is removed when the graft is in a fully deployed state.

    Abstract: An aortic stent-graft may include a tubular graft extending from a proximal end to a distal end, the graft comprising a proximal sealing portion and an intermediate portion, wherein a proximal end of the intermediate portion abuts the distal end of the proximal sealing portion. At least one sealing stent may be attached to the proximal sealing portion. A first fenestration window is disposed in the intermediate portion. The first fenestration window has a length determined by the equation L=1.23*D?24 millimeters, where L is the length of the first fenestration window. D is between about 24 millimeters and 45 millimeters.

  • Endoluminal prosthesis delivery system and method
    Patent number: 9763816
    Abstract: A first endoluminal prosthesis coupled to an inner catheter and a dilator tip is delivered to the body vessel via a guidewire and a delivery sheath in a conventional manner. After deployment of the first endoluminal prosthesis at the target site, the dilator and catheter are retracted from the body, leaving the delivery sheath in place. A second endoluminal prosthesis is housed within a peel-away sheath without a catheter or dilator tip, and is mated to the delivery sheath outside the patient. The second prosthesis is advanced from the peel-away sheath into the delivery sheath without the use of a dilator tip or catheter. As the second prosthesis is advanced into the delivery sheath from the peel-away sheath, the peel-away sheath is peeled away. The second prosthesis is advanced through the delivery sheath and delivered into an overlapping engagement with the first prosthesis.

  • Stent graft and introducer assembly
    Patent number: 9757263
    Abstract: A stent graft (40) for treating Type-A dissections in the ascending aorta (22) is provided with a plurality of diameter-reducing suture loops (56-60) operable to constrain the stent graft during deployment thereof in a patient's aorta. The diameter-reducing loops (56-60) allow the stent graft (40) to be partially deployed, in such a manner that its location can be precisely adjusted in the patient's lumen. In this manner, the stent graft can be placed just by the coronary arteries (26, 28) with confidence that these will not be blocked. The stent graft (40) is also provided with proximal and distal bare stents (44,52) for anchoring purposes.

  • ENDOLUMINAL PROSTHESIS WITH STEERABLE BRANCH
    Publication number: 20170252145
    Abstract: An endoluminal prosthesis may include a tubular main graft body including a sidewall and proximal and distal ends. A first stent may be positioned near the proximal end of the main graft body. A second stent may be positioned adjacent to and distal of the first stent. An opening in the sidewall may be positioned longitudinally between a peak of the first stent and a valley of the second stent. A tubular branch may be disposed in the opening. The branch may include first and second end openings. The branch may be flexibly orientable between a retrograde configuration in which the first end opening is oriented toward the distal end and the second end opening is oriented toward the proximal end and an antegrade configuration in which the first end opening is oriented toward the proximal end and the second end opening is oriented toward the distal end.

  • Paraplegia prevention stent graft
    Patent number: 9724187
    Abstract: A stent graft for deployment into the aorta of a patient has a tubular body with a proximal portion of a selected diameter; preferably a reduced diameter portion, distal of the proximal portion, having a diameter less than the selected diameter; a tapered portion, extending between the proximal portion and the reduced diameter portion; and optionally a distal portion, distal of the reduced diameter portion. At least three, preferably four or five, low profile side arms are provided, preferably in the reduced diameter portion and/or the tapered portion, for connection of an arm extension to an aortic branch vessel. All but one of the side arms are to be connected at the physician's choice, depending on the anatomy of the patient. One side arm is to provide temporary profusion to external of the stent graft after deployment of the stent grant into the aorta, and is subsequently blocked.
