  • Patent number: 11986189
    Abstract: An apparatus for treating an aneurysm in a blood vessel includes an occlusion element configured to be releasably coupled to an elongate delivery shaft and configured to be delivered in a collapsed configuration through an inner lumen of a delivery catheter, the occlusion element including an inverted mesh tube having an outer layer and an inner layer, the outer layer transitioning to the inner layer at an inversion fold, wherein at least the outer layer is formed into a first expanded shape including: a smooth outer cylinder configured to engage a wall of an aneurysm throughout a 360° circumference; and a substantially distal-facing surface including one or more heat-formed undulations, the one or more undulations configured to apply a radial force on the wall of the aneurysm.

  • Publication number: 20240099723
    Abstract: An occlusion device includes a braided mesh body and at least one pinch member. The braided mesh body comprises plural strands each having a first end portion and a second end portion. The plural strands fold over to bring the second end portions of the plural strands adjacent to the first end portions of the plural strands forming a double-layer of the braided mesh body. In an example occlusion device, at least one of the plural strands is radiopaque, and the at least one pinch member is non-radiopaque.

  • Patent number: 11723678
    Abstract: An obstruction removal device is configured to be inserted through a catheter and at least partially extended into a vasculature from a distal end of the catheter. The obstruction removal device includes: a base member configured to engage one or more guide stops at the distal end of the catheter; a tubular member coupled to the base member and configured to apply a suction force from the catheter to an obstruction to remove the obstruction from the vasculature; and an expandable member surrounding the tubular member. The expandable member is configured to transition from a contracted state to an expanded state after the expandable member is at least partially extended into the vasculature from the distal end of the catheter. The expandable member is further configured to at least partially surround the obstruction as the obstruction is being removed from the vasculature.

  • Patent number: 10835272
    Abstract: A system for removing embolic material from an intravascular site is disclosed. The system includes an elongate, flexible tubular body, having a proximal end, a distal end, and a tubular side wall defining at least one lumen extending axially there through; an axial restraint carried by the side wall and exposed to the lumen; a rotatable core wire extendable through the lumen, the core wire having a distal end; a limit carried by the core wire, the limit having a bearing surface for rotatably engaging the restraint; and an agitator tip on the distal end of the core wire. The limit and the restraint are engageable to permit rotation of the core wire but limit distal advance of the tip relative to the tubular body.
