Abstract
Mechanical thrombectomy apparatuses (devices, systems, etc.) and methods for deploying and/or positioning them within a vessel and/or using them and/or removing a thrombus, e.g., clot, from within a vessel using them.
Claims20
An apparatus for removing a clot from a vessel, the apparatus comprising:
- an inversion support catheter having a proximal end, a distal end, and a distal end opening, wherein the distal end of the inversion support catheter is expandable to assume a funnel shape;
- a tractor comprising a flexible tube that extends within the inversion support catheter, inverts over the distal end opening of the inversion support catheter, and extends over an outer surface of the inversion support catheter, wherein the tractor is configured to invert by rolling over the distal end opening of the inversion support catheter when a first end of the tractor is pulled proximally within the inversion support catheter;
- and
- a puller having a distal end coupled to the first end of the tractor, wherein the puller extends proximally within the inversion support catheter.

- a sleeve disposed on the distal end of the inversion support catheter, wherein the sleeve is expandable to assume the funnel shape;
- and
- a puller having a proximal end and a distal end, wherein the first end of the tractor is coupled to the puller, and wherein the distal end of the inversion support catheter is configured to expand to assume the funnel shape when the puller is pulled proximally to roll the tractor over the distal end opening.
