  • Patent number: 11871947
    Abstract: A clot removal device has a segment that has two main struts that serve as a frame for holding a plurality of secondary struts. Each of the two main struts has a proximal end that is connected at a proximal point of the segment and extends along a generally circumferential path, with each main strut terminating at a separate connecting point that is distal from the proximal point. The connecting points are connected to each other to form a generally tubular structure defining an inner lumen. The plurality of secondary struts forms a lattice of cells, with each cell surrounded by four secondary struts. Two generally straight distal struts are connected to the lattice of cells at a distal end of the segment, and are connected to each other to form a distal point. A distal opening is defined by the cells adjacent the distal struts, the distal opening communicating with the lumen and terminating at the proximal point.

  • Publication number: 20220022901
    Abstract: A clot removal device has an expandable treatment member, a proximal section, and a transition section having a distal end connected to the proximal end of the expandable treatment member, and a proximal end connected to the distal end of the proximal section. A delivery wire has a distal end coupled to the proximal section. The diameter of the proximal section is smaller than the diameter of the expandable treatment member, and the transition section has a diameter that varies from its proximal end to its distal end.

  • Publication number: 20220000503
    Abstract: The present invention provides devices for removing an embolus or thrombus. The device includes an elongate member configured for insertion into the vasculature, an expandable member that extends from the distal end of the elongate member, and a flow restrictor associated with a proximal portion of the expandable member. The expandable member is configured to transition from a compacted state to an expanded state, in which the expandable portion engages with the embolus. The flow restrictor is configured to restrict blood flow and generate a low pressure zone at a location in the vasculature that is distal to the flow restrictor.

  • Publication number: 20210038236
    Abstract: A clot removal device has an expandable treatment member having a distal tip and a proximal end, a delivery wire having a distal end coupled to the proximal end of the expandable treatment member, and a flow restrictor carried along the delivery wire at a location that is separate and proximal from the expandable treatment member. The flow restrictor has a body with a distal section and a proximal section, the distal section being covered and the proximal section being uncovered. The expandable treatment member is moveable relative to the flow restrictor, and can be retracted into the distal section.
