  • Patent number: 11344402
    Abstract: 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.

  • Patent number: 11304794
    Abstract: The techniques of this disclosure generally relate to modular stent device and method of deploying the same. The method includes introducing a delivery system including the modular stent device via supra aortic access. The delivery system is advanced into the ascending aorta. Once positioned, the modular stent device is deployed from the delivery system such that an artery leg of the modular stent device engages the brachiocephalic artery and a bypass gate engages the aorta, wherein the artery leg partially collapses the bypass gate. The artery leg has a greater radial force than the bypass gate such that the artery leg remains un-collapsed and opened. Accordingly, blood flow through the artery leg and perfusion of the brachiocephalic artery and preservation of blood flow to cerebral territories including the brain is insured.

  • Patent number: 11020252
    Abstract: A stent assembly includes a framework having a tubular rest shape that defines a longitudinal axis, has an external surface that defines an expanded perimeter, and an internal surface that defines a passageway. The framework has a folded shape with a cross section perpendicular to the longitudinal axis that fits in a closed shape having a perimeter that is smaller than the expanded perimeter. The stent assembly has a constrained configuration characterized by the framework being held in the folded shape by a trigger wire supporting sheer stress by being in contact with interlaced loops of the framework. The stent assembly has an unconstrained configuration characterized by the framework being in the tubular rest shape with the trigger wire out of contact with the framework.

  • Patent number: 10945829
    Abstract: A stent/graft assembly includes a tubular graft connected in substantially end-to-end relationship with a generally tubular stent. Free ends of the stent and graft extend in opposite directions from the end-to-end connection during a pre-deployment orientation of the assembly. However, the graft is inverted during deployment so that free ends of the graft and the stent extend in substantially the same direction from the end-to-end connection in a post-deployment orientation. Thus, at least a portion of the stent is disposed within at least a portion of the graft in a post-deployment orientation of the assembly.

  • Patent number: 10945868
    Abstract: Thin-film mesh for medical devices and related methods are provided. The thin-film mesh may include slits to be expanded into pores, and the expanded thin-film mesh may be used as a cover for a stent device. The thin-film mesh has a tube-shape and the slits may be angled with respect to a longitudinal axis of the tube-shape thin-film mesh. The angled slits allow for the thin-film mesh to expand in multiple dimensions, including along the longitudinal axis and along the circumferential direction of the tube-shape thin-film mesh. The slits may be provided in diagonal rows arranged in longitudinal columns. Longitudinal columns of different types of slits may be arranged along the circumferential direction on the tube-shape thin-film mesh to form a zig-zag pattern of slits. The thin-film mesh may be formed from thin-film Nitinol (TFN) and may be fabricated via sputter deposition on a micropatterned wafer.
