Abstract
An aspiration catheter assembly including an outer catheter having an elongate tubular body and a distal valve at a distal end of the aspiration catheter assembly, and an inner catheter configured to communicate with a vacuum source, the inner catheter being within the outer catheter and including an aspiration lumen for receiving at least a portion of a clot. The distal valve is configured to be opened and closed at the distal end of the aspiration catheter assembly, and the distal end of the aspiration catheter assembly is configured as a separator such that the portion of the clot can be separated at the distal end and drawn into the aspiration catheter assembly.
