  • Publication number: 20240374273
    Abstract: A mechanical thrombectomy apparatus for removing a clot from a vessel includes an elongate inversion support catheter having a distal end opening, an elongate puller extending within the support catheter, and a knitted tractor tube extending over an outer surface of the support catheter, inverting into the distal end opening of the support catheter, and attached to the elongate puller at a first end within the support catheter, wherein the portion of the knitted tractor tube extending over the support catheter comprises a wire forming a helical spiral of alternating teardrop shaped-links each having a rounded apex, wherein each link is connected to two adjacent links so that the apex of each link is on an outward-facing surface of the tractor tube, wherein the links flare outward from an outer wall of the support catheter when the puller is pulled proximally within the support catheter.
