1. A thrombectomy catheter system, comprising:
an inversion support catheter having an outer surface, a distal end, and a lumen;
a first inverting flexible tube sub-assembly loaded onto the inversion support catheter, the first inverting flexible tube sub-assembly including a first flexible tube and a first puller coupled to the first flexible tube;
wherein the first inverting flexible tube sub-assembly is configured to be removed from the inversion support catheter;
a second inverting flexible tube sub-assembly, the second inverting flexible tube sub-assembly including a second flexible tube and a second puller coupled to the second flexible tube;
wherein the second inverting flexible tube sub-assembly is configured to be loaded onto the inversion support catheter after the first inverting flexible tube sub-assembly is removed from the inversion support catheter, wherein the second inverting flexible tube sub-assembly is configured to be advanced through the distal end of the inversion support catheter and into the lumen, and a portion of the second inverting flexible tube sub-assembly inverts over the distal end of the inversion support catheter and extends along the outer surface of the inversion support catheter;
wherein the first inverting flexible tube sub-assembly further comprises a cuff;
wherein the cuff is slidable along the inversion support catheter; and
wherein the cuff is configured to split apart when the cuff reaches a distal end of the inversion support catheter.
