  • Publication number: 20190239907
    Abstract: A method of removing clot from a vessel, including delivering a clot retrieval device across the clot, wherein the clot retrieval device includes an inner body having a collapsed delivery configuration and an expanded deployed configuration; and an outer body extending along a longitudinal axis and at least partially overlying the inner body. The outer body includes a first scaffolding section, a second scaffolding section hingedly connected distal of the first scaffolding section; the first and second scaffolding sections of the outer body being expandable to a radial extent which is greater than the radial extent of the inner body in the deployed configuration to define a clot reception space between the inner and outer bodies. The method also includes expanding the clot retrieval device; and urging, by the expanding of the first and second scaffolding sections, at least a portion of the clot therebetween.

  • Patent number: 10299811
    Abstract: A clot retrieval device (9501) for removing clot from a blood vessel comprises an inner elongate body (9503) and an outer elongate body (9504) at least partially overlying the inner elongate body (9503). The device also comprises an elongate member or shaft (9502) having a proximal end which extends exterior of a patient so that a user can retrieve the stent-basket device and captured clot by retracting the shaft (9502). The outer elongate body (9504) and the inner elongate body (9503) are connected to the distal end of the shaft (9502) and are expandable relative to the shaft (9502) from a collapsed delivery configuration to an expanded deployed configuration. The outer elongate body (9504) is expandable relative to the inner elongate body (9503) to a radial extent which is greater than the radial extent of the inner body (9503) in the deployed configuration.

  • Patent number: 10292723
    Abstract: A clot retrieval apparatus 1 comprises a clot engaging device 2 and a capture basket 3. The clot engaging device 2 has a collapsed delivery configuration and an expanded deployment configuration. The clot engaging device has a proximal end and a distal end and an elongate body between the proximal end and the distal end. The capture basket 3 has a collapsed delivery configuration and an expanded deployment configuration. The capture basket 3 has a proximal mouth which is open when the capture basket 3 is in the deployment configuration. The clot engaging device 2 is axially movable relative to the capture basket for capture of a clot.
