HEART VALVE AND ENDOVASCULAR GRAFT COMPONENTS AND METHOD FOR DELIVERY
An aortic arch graft includes a generally cylindrical member formed from a plurality of struts having a proximal end and a distal end and a longitudinally extending lumen. The proximal end is configured for deployment within the ascending aorta and the distal end configured for deployment in the descending thoracic aorta. The aortic arch graft includes a graft material having an opening disposed between the proximal end and distal end with a plurality of radiopaque markers disposed around a periphery of the opening. The opening within the graft material allows blood flow transverse to the longitudinal lumen of the generally cylindrical member.
VASCULAR PROSTHESES, DELIVERY SYSTEMS, AND METHODS TO TREAT AORTIC ANEURYSMS AND DISSECTIONS
A vascular prosthesis for implantation at an aortic arch of a human patient includes major tubular component defining a longitudinal axis and an island graft that has a length parallel to the longitudinal axis that is greater than a width transverse to the longitudinal axis. The vascular prosthesis delivery system includes a vascular prosthesis of the invention. The vascular prosthesis can also be a hybrid vascular prosthesis, including a proximal surgical segment that can be corrugated, an endovascular stent graft segment extending distally from the surgical segment, and a collar interposed between the surgical segment and the endovascular stent graft segment. The island graft can be pleated or corrugated and can be radially raised from a surface of the major tubular component.
Endovascular graft systems and methods for deployment in main and branch arteries
Endovascular systems for deployment at branched arteries include a main tubular graft body deployable within a main artery including a proximal end and an opposed distal end. The proximal and distal ends have a tubular graft wall therein between. A plurality of inflatable channels are disposed along the main tubular graft body, and at least one stent segment is disposed along the tubular graft wall of the main tubular graft body. The plurality of inflatable channels are configured to be inflatable with an inflation medium. The at least one stent segment is disposed between two or more adjacent inflatable channels of the plurality of inflatable channels.
Delivery systems and methods of endoluminal delivery of branched vascular endoprosthetic devices
A catheter assembly for delivery of an expandable implant having at least one branch portal, which utilizes a secondary sleeve for releasably constraining a middle portion of the expandable implant after releasing a primary constraining sleeve used for constraining the expandable implant toward a delivery configuration for endoluminal delivery; and methods of using the same.
APPARATUS AND METHOD OF PLACEMENT OF A GRAFT OR GRAFT SYSTEM
A fenestrated graft deployment system, with a delivery catheter having a catheter body, An endoluminal prosthesis having a main graft body, the main graft body having a lumen therethrough and a first opening laterally through a wall of the main graft body. A first guidewire prepositioned within the delivery catheter extending through at least a portion of the catheter body into a main lumen of the endoluminal prosthesis and through the first opening in the wall of the prosthesis when the delivery catheter is in a predeployed configuration. A first fenestration alignment device is configured to extend through at least a portion of the delivery catheter and is configured to be axially moveable relative to the first guidewire. The first fenestration alignment device has an end portion having an outside perimeter configured such that when an end portion of the fenestration alignment device moves toward the first opening of said main graft body the outside perimeter of the first opening is smaller than the outside perimeter of the first fenestration alignment device and prevents it from passing through the first opening and causes the main graft body adjacent to the first opening to move with the end of the first fenestration alignment device to act as alignment tool to allow an operator to align the first opening in the side of the endoluminal prosthesis with an ostium of a target branch vessel into which said first opening is to extend and act as a guide and seal for a subsequently delivered branch graft endoluminal prosthesis.
Aortic graft assembly
An aortic graft assembly includes a tubular component that defines a wall aperture having a proximal end that extends perpendicular to a major longitudinal axis of the tubular aortic component, and a tunnel graft connected to the wall of the tubular aortic component and extending from the wall aperture toward a proximal end of the tubular aortic component. The aortic graft assembly is delivered to a patient through the wall aperture and into interfering relation with the tunnel graft to treat aortic aneurysms.
Delivery system and method to radially constrict a stent graft
A delivery system includes a handle, a guidewire catheter, a nose cone at the distal end of the guidewire catheter that with the guidewire catheter defines an opening concentric with the guidewire catheter, a plurality of wires that extend distally from the handle and essentially parallel with and distributed radially about the guidewire catheter and a stent graft. The wires each extend between a portion of the stents and wall of the stent graft, whereby the stent graft is radially constrained until the wires are retracted. The delivery system can be employed in methods of treating arterial disease, such as aortic aneurysms.
DEVICES AND METHODS FOR TREATING BIFURCATING BLOOD VESSELS
Medical devices and methods for placing a bifurcated stent into a bifurcating blood vessel are described herein. Also, described herein are methods for treating aorto-iliac occlusive disease. The bifurcated stent can be mounted onto a catheter comprising at least two balloons by mounting a first branch stent of the bifurcated stent onto a first balloon and a second branch stent of the bifurcated stent onto a second balloon, and a main body of the bifurcated stent onto the first balloon and second balloon.
Branch stent for implantation from a main blood vessel and deployment methods
A branch stent for implantation from a main blood vessel in a plurality of branch blood vessels having respective branch blood vessel diameters, the branch stent comprising: a tubular element having: an axis of elongation; a first and a second tubular element end; the tubular element covered with a tubular element cover; and a parachute element having an unconstrained flat-toroid/disc configuration, the parachute element having a parachute element cover, the parachute element positioned perpendicularly at the second tubular element end, and positioned coaxially to the axis of elongation; wherein the branch stent is implanted from within a fenestrated stent-graft having oversized fenestrations, the fenestrated stent-graft first implanted in the main blood vessel at a bifurcation zone including the plurality of branch blood vessels, with each of the oversized fenestrations having respective diameters larger than respective branch blood vessel diameters; wherein the branch stent and the fenestrated stent-graft are together a multi-stent.
CUSTOMIZED GUIDE, AND APPARATUS AND METHOD FOR MANUFACTURING SAME
A customized guide includes a body having a shape corresponding to a main vessel in biological tissues that includes the main vessel and an accessory vessel branching from the main vessel, and an indicator provided in the body to indicate a branching location of the accessory vessel.
