1. A mechanical thrombectomy apparatus for removing a clot from a vessel without jamming, the apparatus comprising:

  • an elongate inversion support comprising a catheter having a distal end and a distal end opening;

    a tractor comprising a flexible tube that extends distally in an un-inverted configuration within the catheter, inverts over the distal end opening of the catheter and extends proximally in an inverted configuration along the distal end of the catheter, wherein the tractor comprises a tubular wall, further wherein the tractor is configured to invert by rolling over the distal end opening of the catheter when a first end of the tractor is pulled proximally within the catheter,wherein the tractor is biased to expand to have an inner diameter that is greater than the outer diameter of the catheter in the inverted configuration and is biased to expand to have an inner diameter that is greater than the inner diameter of the catheter in the un-inverted configuration; and

    an elongate puller coupled to the first end of the tractor.
