  • Patent number: 12023057
    Abstract: A method is disclosed for removing a vascular occlusion, such as a clot, from a blood vessel. A tubular sheath is inserted into the vessel and a self-expanding Nitinol mesh filter is deployed from a distal end of the tubular sheath at a location proximal to a clot. An inner catheter is advanced through the tubular sheath and through the mesh filter for contacting the clot. An expandable agitation element is provided along a distal end portion of the inner catheter for cutting or chopping the clot, thereby facilitating removal of the clot and improving blood flow through the vessel. Resulting clot particles are captured by the mesh filter. Negative pressure may be applied along a proximal end portion of the sheath for aspirating remaining particles. Certain embodiments of the method are well-suited for treating deep vein thrombosis and do not require the use of thrombolytic drugs.

  • Patent number: 12004758
    Abstract: An improved catheter is provided for removing an obstruction(s) from a blood vessel, for example, for retrieving a clot/thrombus in the neurovasculature for the treatment of stroke. The catheter has a collapsed state sufficiently small and flexible for easier delivery through challenging vasculature and also has an expanded state sufficiently sized and robust for removing the obstruction. The catheter may include a self-collapsing and expanding mechanism to transition a portion of an outer tube (e.g., a braided portion) between the collapsed and expanded states. Such mechanism may include an inner actuator tube slidable over an actuation wire to collapse a distal branched section of the actuation wire, thereby collapsing the braided portion. The catheter may also include an intermediate coiled tube for reinforcing the braided portion in the expanded state.
