1. A clot retrieval device comprising:
- —
an elongate shaft having a proximal end and a distal end; and
a clot retrieval element at the distal end of the elongate shaft,a proximal end of the elongate shaft of the clot retrieval device being adapted for retraction of a first catheter over said clot retrieval device elongate shaft, a second catheter being advanced to or adjacent to the distal end of the clot retrieval device shaft to enable enhanced aspiration adjacent to the clot retrieval element.
