  • Publication number: 20200281603
    Abstract: Methods and devices for treatment of a patient's cerebral aneurysm is described. The device includes a permeable shell having a radially constrained elongated state configured for delivery within a catheter lumen, an expanded state with a longitudinally shortened configuration relative to the radially constrained state, and a plurality of elongate filaments that are woven together to form a mesh. The proximal ends of each of the plurality of filaments are gathered by a proximal hub and the distal ends of each of the plurality of filaments are gathered by a distal hub. The proximal portion of the permeable shell includes a swellable polymer. The method includes advancing the implant in a microcatheter to a region of interest in the cerebral vasculature, deploying the implant within the cerebral aneurysm, and withdrawing the microcatheter from the region of interest after deploying the implant.

  • Patent number: 10709471
    Abstract: A method and apparatus for treating a clot in the blood vessel of a patient, and particularly the treatment of a pulmonary embolism is disclosed. The treatment includes restoring flow through the clot followed by clot removal, either partially or substantially completely. The clot treatment device is expandable into the blood vessel and may contain radial extensions that assist in restoring flow as well as in removing clot material.

  • 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 The microcatheter is then withdrawn from the cerebral artery.

  • Publication number: 20180344339
    Abstract: A system and method for managing an occlusion, such as a blood clot, within a lumen or passageway of a patient. More particularly, a system and method for rapidly restoring blood flow through an occlusion including a self-expanding, tubular member through which blood may flow when in an expanded state. The tubular member has a structure configured to engage the occlusive material, thereby allowing for extraction of at least a portion of the occlusive material. The system may further employ a material extraction member that is deployed distally of the tubular member.

  • Publication number: 20170245862
    Abstract: Methods of implanting a device in the lumen of a blood vessel are described. The method includes providing a microcatheter and a device. The device includes a first hub, a second hub, a support structure including a plurality of struts disposed between the first hub and the second hub, and a layer of material disposed over the plurality of struts. The support structure has a low profile, radially constrained state with an elongated tubular configuration suitable for delivery from a microcatheter. The support structure also has an expanded state, a smooth outer surface, and has an axially shortened configuration relative to the radially constrained state. The microcatheter is advanced to a region of interest within the blood vessel. The support structure is advanced through the lumen of and out the distal end of the microcatheter where it expands to the expanded state.
