  • Publication number: 20230013548
    Abstract: A clot capture catheter having an outer inflatable expansile member and an inner inflatable expansile member positioned within the outer inflatable expansile member at a distal end of a shaft of the catheter is presented herein. The inner and outer inflatable expansile members can have differing compliance than each other. Inflation of a higher compliance inner inflatable expansile member can cause a lower compliance outer inflatable expansile member to shorten and provide tension to the distal end of the shaft to case the distal end to open to a funnel shape. Inflation of a lower compliance inner inflatable expansile member can center the distal end of the shaft within a vessel, and inflation of a higher compliance outer inflatable member can provide atraumatic flow arrest to the vessel.
