  • Publication number: 20210030540
    Abstract: Embodiments of the present disclosure provide an introducer device and method for introducing a delivery apparatus into a patient's vasculature. Disclosed methods can include positioning a sleeve of an introducer sheath in a blood vessel of a patient, the sleeve having a lattice layer with a lumen therethrough, inserting a distal end portion of the delivery apparatus and a prosthetic heart valve into the lumen, and advancing the distal end portion of the delivery apparatus through the lumen from the proximal end to the distal end. The method can then include expanding the lumen from a first diameter smaller to a second diameter at least equal to the diameter of the prosthetic heart valve to allow passage of the prosthetic heart valve through the lumen, and returning the lumen of the sleeve to a diameter smaller than the second diameter after advancing the prosthetic heart valve through the lumen.

  • Patent number: 10907283
    Abstract: Methods of braiding using a braiding mechanism are described. The braiding machine includes first and second annular members, the second annular member being concentric with the first annular member. A mandrel extends perpendicularly to and intersects a horizontal plane defined by a substantially circular region of the second annular member substantially at the center of the circular region. Each of the annular members has a plurality of tubular guide wires slideably mounted thereon and a plurality of wires extend from the mandrel through each of the tubular wire guides. The first annular member rotates circumferentially relative to the second annular member. The first plurality of tubular wire guides slides radially inward to align with the second annular member, and the second plurality of tubular wire guides slides radially outward so as to align with the first annular member.

  • Patent number: 10610231
    Abstract: Methods for treatment of a cerebral aneurysm within a cerebral vasculature of a patient are described. A microcatheter and a device for treatment of the aneurysm are provided. The device is a self-expanding resilient permeable shell having a plurality of elongate resilient filaments with a woven structure. The plurality of filaments includes small and large filaments. The filaments are bundled and secured to each other at a proximal end. A ratio of the total cross-sectional area of small filaments to the total cross-sectional area of large filaments may be between 0.56 and 1.89. The distal end of the microcatheter is advanced to a region of interest within a cerebral artery. The device is advanced through the lumen and out of the distal end of the microcatheter such that the permeable shell deploys and expands within the cerebral aneurysm. The microcatheter is then withdrawn from the cerebral artery.
