  • Patent number: 10111676
    Abstract: A clot retrieval system for removing clots from a body lumen. The clot retrieval system includes an elongated sheath and a wire assembly. The wire assembly is comprised of four wire segments, each biased to have a distally extending circumferential curve. Two wire segments are connected together at a proximal end and a distal end to form a first loop, and are connected to a shaft. Two other wire segments are connected together at a proximal end and a distal end to form a second loop and are connected to the first two wire segments. The second loop is covered with a membrane to catch clots. The wire assembly may be compacted by retracting it within the elongated sheath, or expanded by extending it from the elongated sheath.
