A visceral double-barreled main body stent graft and methods for its use, the stent graft comprises, a main body stent graft having distal and proximal ends, the main body stent graft's length ranges from about 100-120 mm and diameter at the proximal end ranges from about 30-45 mm, first and second lumens defined at the main body stent graft's distal end, the first lumen's diameter ranges from about 18-20 mm, the second lumen's diameter ranges from about 16-18 mm, the first and second lumens have about the same length from about 50-70 mm, the first lumen is secured to the second lumen along a shared length, and the main body stent graft defines a tubular wall that is contiguous with the first and second lumens such that any fluid entering the main body must exit through one of the first or second lumens.

A method of connecting an expansion ring to at least one end of a braided implant, the method including positioning the braided implant about a tube; everting an end portion of the braided implant over a first end of the tube; assembling an expansion ring to the braided implant, the expansion ring being a multi-leaved expansion ring comprising clips terminating with an open-ended coupling opening, wherein the openings are pushed over a set of intersecting wires of the braided implant at respective circumferential locations on or adjacent the first end of the tube; closing the openings over the set of intersecting wire; trimming ends of the braided implant; and reversing eversion of the braided implant thereby positioning the expansion ring internal to the braided implant.

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.

Apparatus and methods are described for regulating blood flow in an ascending aorta of a subject including inserting a device into the ascending aorta. When in a deployed state, the device defines an inner surface that defines a conduit through the device, at least a portion of the inner surface diverging, such that a cross-sectional area of the conduit at the downstream end of the diverging portion is greater than a cross-sectional area of the conduit at the upstream end of the diverging portion. The device is deployed within a longitudinal portion of the ascending aorta, such that the device defines the conduit throughout deployment of the device within the longitudinal portion of the ascending aorta. Other applications are also described.
