  • Patent number: 11045204
    Abstract: Described herein are flexible implantable devices or stents that can conform to the shape of vessels of the neurovasculature. In some embodiments, the devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. In some embodiments, a vascular remodeling device includes a first section and a protruding section. During deployment, the device expands from a compressed configuration to an expanded configuration. The first section anchors the device in an afferent vessel and/or in an efferent vessel of a bifurcation and the protruding section is positioned in the junction of the bifurcation having an aneurysm and across the neck of the aneurysm or at least partially within the aneurysm.

  • Patent number: 10098657
    Abstract: A device for intravascular intervention can comprise an intervention element and an elongate manipulation member. The elongate member can comprise a hooked portion extending about a proximal portion of the intervention element. The hooked portion can have a first segment, a second segment, and a bend between the first and second segments, with the first segment and the second segment located on different sides of the intervention element. At least one of the first segment or the second segment can have an extending portion that extends into a region that is (i) between a top side and a bottom side of the intervention element, and (ii) distal to a proximal part of the intervention element. The extending portion and the proximal part can be aligned such that a line extending in a proximal-distal direction intersects the extending portion and the proximal part.

  • Patent number: 9943427
    Abstract: A self-expanding stent includes a proximal portion having a first cross-sectional area in an expanded state, a distal portion having a second cross-sectional area in an expanded state, a narrowed portion between the proximal portion and the distal portion, the narrowed portion comprising a cross-sectional area when in an expanded state that is less than the first cross-sectional area and the second cross-sectional area, wherein the narrowed portion is configured to increases flow velocity in the narrowed portion while reducing reduce pressure against a distal wall of the aneurysm by being axially disposed substantially between a proximal edge and a distal edge of an aneurysm neck or ostium, the flow traversing through the lumen of the self-expanding stent. In use, the self-expanding stent is positioned at the site of an aneurysm and expanded via release from a stent delivery device.

  • Patent number: 9351859
    Abstract: Described herein are vascular remodeling devices that include a proximal section, an intermediate section, and a distal section. During deployment, the proximal section can expand from a compressed delivery state to an expanded state and anchors the device in an afferent vessel of a bifurcation. The distal section expands from the compressed delivery state to an expanded state that may be substantially planar, approximately semi-spherical, umbrella shaped, or reverse umbrella shaped. The distal section is positioned in a bifurcation junction across the neck of an aneurysm or within an aneurysm. The intermediate section allows perfusion to efferent vessels. Before or after the device is in position, embolic material may be used to treat the aneurysm. The distal section can act as a scaffolding to prevent herniation of the embolic material. The device can be used for clot retrieval with integral distal embolic protection.
