Clot retrieval system for removing occlusive clot from a blood vessel

Abstract

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 configured to retract a first catheter over the elongate shaft. The shaft extension member comprising one or more raised profiles configured to interfere with one or more indentations along the elongate shaft such that the shaft extension member is configured to extend between a first length and an intermediate length. A second catheter is advanced to or adjacent to the distal end of the clot retrieval device shaft to enable enhanced aspiration adjacent to the clot retrieval element.
