Abstract

A method of operating an aspiration catheter having a proximal end and a distal end includes the acts of at least partially blocking the distal end of the aspiration catheter with an embolus, creating a vacuum at the distal end of the aspiration catheter with a vacuum source adjacent the proximal end of the aspiration catheter, at least partially relieving the vacuum at the distal end of the catheter by at least one of interrupting the vacuum from the vacuum source and venting the aspiration catheter with a vent fluid adjacent the proximal end, and repeating the acts of interrupting the vacuum and venting the aspiration catheter in a timing cycle that maximizes the time that the aspiration catheter is at vacuum and changes pressure at the distal end of the catheter from vacuum to at least atmospheric pressure during each cycle.
