The intravascular stent is usable for iliac vein, with good supporting effect for iliac vein and less damage to venous wall, and can effectively avoid forming in-stent secondary thrombosis after intravascular stent implantation. Moreover, the intravascular stent is positionable in the iliac vein to improve the accuracy of the release.

  • Patent number: 10667899
    Abstract: An endoluminal graft system comprising an endoluminal graft including a framework and a flexible fabric surrounding the framework, a deflection means configured for placement through an opening to a branching vessel, and a delivery catheter configured to position the endoluminal graft within a primary vessel. A method of implanting the endoluminal graft includes positioning the endoluminal graft within a primary vessel with a leading edge of the endoluminal graft adjacent to an opening to a branching vessel. A deflecting means is positioned through the opening to the branching vessel adjacent to the leading edge of the endoluminal graft. The endoluminal graft is then advanced along the length of the primary vessel with the deflection means engaging the leading edge of the endoluminal graft to form a scallop along the leading edge of the endoluminal graft.

  • Patent number: 10639147
    Abstract: Embodiments of a crimping device for crimping a radially expandable and compressible prosthetic valve are disclosed. A crimping device can comprise a housing configured to receive a prosthetic valve in a radially expanded state. The housing member can include a funnel segment and an outlet in communication with the funnel segment. The crimping device can further comprise an actuator rotatably coupled to the housing, wherein rotation of the actuator relative to the housing causes the prosthetic valve to move axially through the funnel segment such that at least a portion of the prosthetic valve compresses radially by engagement with the funnel segment and exits the crimping device via the outlet.

    Abstract: According to one or more embodiments, a method, a computer program product, and a computer system for detecting and characterizing aortic pathologies are provided. The method may include receiving, by a computer, one or more tomograph scan images corresponding to a patient's aorta. The one or more received tomograph scan images may be analyzed by the computer for one or more image features associated with one or more aortic pathologies, such as aortic dissection or an aortic aneurysm. One or more image features associated with the one or more aortic pathologies may be identified in the one or more analyzed tomograph scan images, which may allow the determination of an aortic pathology associated with the patient's aorta based on the identification of the image features. A portion of the aorta and one or more branch arteries corresponding to the determined aortic pathology may then be identified.
