  • Patent number: 11864988
    Abstract: Methods, devices, and systems establish and facilitate retrograde or reverse flow blood circulation in the region of the carotid artery bifurcation in order to limit or prevent the release of emboli into the cerebral vasculature such as into the internal carotid artery. The methods are particularly useful for interventional procedures, such as stenting and angioplasty, atherectomy performed through a transcarotid approach or transfemoral into the common carotid artery, either using an open surgical technique or using a percutaneous technique, such as a modified Seldinger technique or a micropuncture technique.
    Type: Grant
    Filed: September 9, 2021
    Date of Patent: January 9, 2024
    Assignee: Silk Road Medical, Inc.
    Inventors: Sumaira MacDonald, Stewart M. Kume
  • Publication number: 20220378565
    Abstract: Devices and methods are configured to allow transcarotid or subclavian access via the common carotid artery to the native aortic valve, and implantation of a prosthetic aortic valve into the heart. The devices and methods also provide for embolic protection during such an endovascular aortic valve implantation procedure.
