These mechanical thrombectomy apparatuses may include a tractor comprising a flexible tube of material that inverts as it rolls over itself while being drawn into a catheter in a conveyor-like motion. In particular, described herein are mechanical thrombectomy apparatuses having tractors selectably extendable projections that may aid in grabbing and/or macerating a clot. Also described herein are seesawing tractors for mechanical thrombectomy apparatuses.
