A stent graft assembly including a main body and a branch coupling extending radially from the main body. A proximal end of the single branch stent device is configured to seal in an ascending portion of an aorta. The assembly further includes a modular stent device including a proximal end and a distal end. The proximal end of the modular stent graft is configured to couple to a distal end of the single branch stent device. The modular stent device includes a main body configured to couple inside the main body of the single branch stent device. The modular stent device includes a bypass gate and an artery leg. The modular stent device is configured to bifurcate at a bifurcation point from the main body to the bypass gate and the artery leg outside of and distal the distal end of the single branch stent device.

Modular multibranch stent assembly and method

A method of providing support in an aortic region. The method includes wrapping a landing band around an outside of a portion of an aortic vessel in a vicinity of a sinotubular junction (STJ) to form a wrapped portion of the aortic vessel. The method further includes securing the landing band to form a secured landing band. The method also includes endovascularly delivering a stent graft in a radially constricted configuration into the aortic vessel. The method also includes deploying the stent graft to a radially expanded configuration such that the stent graft contacts the wrapped portion of the aortic vessel. The method also includes connecting the stent graft in the radially expanded configuration to the secured landing band.

Aortic landing band support method and system

A stent-graft prosthesis for implantation within a body vessel includes a graft material, a frame, and a channel. The graft material includes a proximal end, a distal end, and a graft lumen extending between the proximal and distal ends. The frame is coupled to the graft material. The channel is configured to relieve pressure associated with pulsatile blood flow during implantation of the stent-graft prosthesis within a body vessel. The channel permits blood to flow from an upstream side of the stent-graft prosthesis to a downstream side of the stent-graft prosthesis when the stent-graft prosthesis is in a partially expanded configuration in the body vessel. The channel may be a plurality of channels.

The techniques of this disclosure generally relate to a stent-graft system including a bifurcated stent-graft, a first bifurcating branch device, and a first branch extension. The bifurcated stent-graft includes a body, a first branch limb, and a second branch limb. The first bifurcating branch device includes a body segment coupled to the first branch limb of the bifurcated stent-graft, a first branch limb, and a second branch limb. The first branch extension is within the first branch limb of the first bifurcating branch device and within an external iliac artery. The first bifurcating branch device has a wide patient applicability since the treatment can be extended proximal to the anatomical iliac bifurcation and is not limited by the common iliac artery length. The stent-graft system is suitable to treat a wide range of internal and external iliac artery diameters.

Bifurcating branch modular iliac branch device

A stent graft delivery system includes a stent graft and a thermal stent graft cutter for shortening the stent graft to a desired length in vivo. The thermal stent graft cutter is coupled to at least one of a stent graft cover at a distal longitudinal end of a cover body thereof, and the inner lumen tip of an inner lumen. A safety system allows activation of the stent graft cutter only when the stent graft is suitably sandwiched between the inner lumen tip and the distal end of the stent graft cover to inhibit inadvertent activation of the cutter and provide for proper cutting of the stent graft.

The techniques of this disclosure generally relate to a modular stent device that is deployed into the ascending aorta via femoral access. The modular stent device is a base or anchor component to which additional modular stent devices can be attached to exclude diseased areas of the aorta while at the same time allowing perfusion of the brachiocephalic artery, the left common carotid artery, and/or the left subclavian artery.

Femoral aortic access modular stent assembly and method

The techniques of this disclosure generally relate to a modular stent device including a main body configured to be deployed in the ascending aorta, a bypass gate configured to be deployed in the aorta, and a bifurcated contra limb. The bifurcated contra limb includes a single proximal limb that is bifurcated (split) into a first distal limb and a second distal limb. By forming the bifurcated contra limb to include a single proximal limb that is bifurcated into the distal limbs, guiding a guide wire into the relatively larger opening of bifurcated contra limb at a proximal end is simpler than guiding a guidewire into two smaller limbs extending distally from main body. Accordingly, cannulation of the bifurcated contra limb is relatively simple thus simplifying the procedure. In addition, the parallel design mimics anatomical blood vessel bifurcations to limit flow disruptions.

The techniques of this disclosure generally relate to an assembly including a single branch stent device and a modular stent device configured to be coupled to the single branch stent device. The single branch stent device includes a main body and a branch coupling extending radially from the main body. The modular stent device includes a main body configured to be coupled inside of the main body of the single branch stent device, a bypass gate extending distally from a distal end of the main body of the modular stent device, and an artery leg extending distally from the distal end of the main body of the modular stent device.

A prosthetic assembly configured for endovascular placement within an aortic arch and method of use thereof. The prosthetic assembly includes a proximal aortic stent-graft prosthesis configured to be positioned within a proximal portion of the aortic arch adjacent to the brachiocephalic artery, a distal aortic stent-graft prosthesis configured to be positioned within a distal portion of the aortic arch adjacent to the left subclavian artery, a first branch stent-graft prosthesis configured to be positioned within the brachiocephalic artery and a second branch stent-graft prosthesis configured to be positioned in one of the left common carotid and the left subclavian artery. When deployed, a proximal end of the first branch stent-graft prosthesis is disposed within a lumen of the proximal aortic stent-graft prosthesis to proximally displace the ostium of the brachiocephalic artery. When deployed, a proximal end of the distal aortic stent-graft prosthesis is disposed within the distal end of the proximal aortic stent-graft prosthesis to form an overlap between the proximal and distal aortic stent-graft prostheses. The overlap is relatively increased by the first branch stent-graft prosthesis proximally displacing the ostium of the brachiocephalic artery.

Modular aortic arch prosthetic assembly and method of use thereof

The techniques of this disclosure generally relate to an assembly including a single multibranch stent device. The single multibranch stent device includes a main body, a proximal coupling extending radially from the main body, and a distal coupling extending radially from the main body. The main body, the proximal coupling, and the distal coupling are permanently coupled to one another and the single multibranch stent device is a single piece. By forming the single multibranch stent device as a single piece, the single multibranch stent device can be deployed in a single deployment thus simplifying the deployment procedure.

Single multibranch stent device assembly and method

Systems and methods for building a landing zone for an endovascular procedure are described. This procedure is 'hybrid' in that it involves both direct access (e.g., sternotomy or partial sternotomy) to the site for installation of the landing zone, as well as endovascular installation of a TAVR or TEVAR device (e.g., stent graft) once the landing zone is installed. The landing zone is installed by wrapping a landing band around a portion of a vessel. The landing band may be selected to be fixed at a diameter so that it inhibits any expansion of the vessel, and also supports a later-installed TAVR or TEVAR device. The TAVR or TEVAR device is then endovascularly delivered to the vessel and deployed therein. The device expands until it contacts the vessel, which is supported from the outside by the landing band, which thus constrains and supports the device from outside.

Landing zone for endovascular procedures

The techniques of this disclosure generally relate to an assembly including a docking graft. The docking graft includes a main graft defining a main lumen, a first internal lumen within the main lumen, a second internal lumen within the main lumen, and a main docking lumen within the main lumen. The first and second internal lumens are configured to receive first and second bridging stent graft therein. The main docking lumen is configured to receive a tube graft therein. The first internal lumen, the second internal lumen, and the main docking lumen being parallel to one another and extending an entire length of the docking graft when the docking graft is in a relaxed configuration. The docking graft forms the foundation, or anchor device, for attachment of the first bridging stent graft, the second bridging stent graft, and the tube graft within the aorta.
