Abstract
A system may comprise a clot engagement element having a collapsed delivery configuration and an expanded configuration for engaging with a clot and for dislodging the clot from a first vessel segment. An elongate member may be configured to apply a pull force to the clot engaging element to dislodge the clot from the first vessel segment. A clot removal catheter may include a lumen at its distal end sized to receive the clot and configured to maintain a stable position in a second blood vessel segment proximal of and larger in diameter than the first blood vessel segment. A distal end of the elongate member may be configured to protect a third blood vessel segment between the first and second blood vessel segments from tractive forces transmitted by the elongate member during clot dislodgement from the first vessel segment.
